ECG Proximity Switches are fully sealed against most hostile industrial environments. They are impervious to oils, organic cleaners, steam, water and dust as well as being immune to vibration. Usual positioning and operational constraints are virtually eliminated, while life span remains unaffected by problems related to mechanical wear. Proximity switches will operate electromechanical devices such as relays, contactors, solenoids, counters and valves without additional interface components. Also, DC types provide an output compatible with solid state loads, including programmable controllers. Proximity switches offer reliable and long-lived operation in applications as diverse as machine tools, conveyors, automated warehouses, wood working machines, robotics, farm machinery, packaging equipment, production lines and general automation. Philips ECG offers a broad range of types to meet the variety of users’ needs. Operating Principle An inductive proximity switch has three functional sections or stages, as shown in Figure 1. They are: a radio frequency (RF) oscillator circuit that incorporates a coil with a ferrite core, a Schmidt trigger circuit, and a solid state output switching device (transistor in DC types, thyristor in AC types). Operating Principle METTALIC TARGET ACTIVE FACE TO LOAD OSC. COIL Fig. 1 TRIGGER CIRCUIT SWITCHING DEVICE Sensing Distance (Sn) This is the distance at which a metallic target approaching the active face in the Axial plane (“head-on”) activates the switch, Figure 3. Sensing Distance Sensing Characteristics The target can approach the switch in either of two ways, as illustrated in Figure 2. In the Axial plane the target approaches “head-on” along the major axis of the switch, perpendicular to the active face. In the Radial plane the target approaches and/or “slides by” the switch along a path parallel to the active face. Target Approach Paths TARGET (OBJECT TO BE DETECTED) AXIAL PLANE RADIAL PLANE ACTIVE FACE ACTIVE FACE TARGET Sn SENSING DISTANCE DIRECTION OF TRAVEL Fig. 3 STANDARD TARGET - See Text Sensing Distance is affected by target size, shape and composition. Therefore, catalog values are given for a Standard Target. This is a square of mild steel (low carbon) 1.0 mm thick with side measurements equal to the diameter of the switch or three times the sensing distance, whichever is greater. Targets which are smaller than the Standard Target, not flat or made of non-ferrous metal will reduce the Sensing Distance. It should be noted that if the target is larger than the Standard Target the Sensing Distance will not be increased. Correction Factors - Non-Ferrous Metals: ECG proximity switches will detect all metals, but have a greater sensitivity to ferrous metals. If non-ferrous metals are to be detected, a shorter Sensing Distance must be used.Listed below are approximate correction factors for certain non-ferrous metals. Material Chrom-Nickel Brass Aluminum Copper SENSING FIELD The oscillator circuit generates an electromagnetic field which is radiated from the active face of the switch. A metal object (target) introduced into this sensing field absorbs energy from the oscillator which, in turn, reduces the amplitude of oscillation. The trigger circuit detects the reduction and in response produces a signal that closes the output stage switching device. When the target leaves the sensing field the oscillator regenerates and the switch resets. ECG Inductive Proximity Switches are responsive to all electrically conductive materials. They cannot, however, distinguish between different materials. Fig. 2 In practice, the target should not come in contact with the switch. A minimum separation between the target and active face is prerequisite and should be assured at all times to prevent mechanical wear. Factor 0.9 x Sensing Distance 0.5 x Sensing Distance 0.4 x Sensing Distance 0.4 x Sensing Distance Sensing Distance vs. Switch Size: Sensing Distance is also directly related to switch diameter. The greater the diameter, the greater the Sensing Distance. Philips ECG offers a broad range of switch diameters to provide just the Sensing Distance required: 8 12 18 30 Switch Diameter in mm (Series 800) (Series 1200) (Series 1800) (Series 3000) Sensing Distance (Sn) in mm Shielded Unshielded 1.5 2.5 2.0 4.0 5.0 8.0 10.0 15.0 Axial and Radial Sensing Characteristics Sensing characteristics in the Axial (head-on) and Radial (slide-by) actuation modes are illustrated in Figure 4. Axial Mode: In this mode or plane note that there is a difference in the distance at which the switch activates (closes) as the target approaches and the distance at which the switch deactivates (opens) as the target recedes. This characteristic is referred to as Switching Hysteresis and is typically 15 percent of the Sensing Distance (Sn). Hysteresis provides compensation for target vibration and minor surface irregularities that might otherwise cause false signals. Radial Mode: In this mode, the distance between the active face of the switch and the target should not exceed 81 per-cent of the specified Sensing Distance (Sn) of the particular switch. Operation within this zone is assured and is independent of variations, within ratings, of temperature and voltage. 129 ECG® Relays and Accessories Sensing Characteristics AXIAL PLANE OPEN HYSTERESIS CLOSE SENSING DISTANCE (Sn) RADIAL PLANE ASSURED OPERATING ZONE Fig. 4 additional wiring. They can operate relays, solenoids, contactors, etc., at switching rates up to 15 operations per second, depending on the switch type. Both shielded and unshielded styles are offered by Philips ECG in 12, 18 and 30 mm sizes with sensing distance of 2 to 15 mm, and operating voltage ranges of 35 to 250 VAC and 90 to 250 VAC. Maximum load current of all types is 250 mA. AC switches are available both with and without Ground, Figure 7. Operation is identical. When not sensing a target, the output is open (non-conductive). When a metal target enters the sensing field the output closes (becomes conductive) and energizes the load. Switching Frequency Switching Frequency represents the maximum number of targets per second that a proximity switch is capable of detecting. As shown in Figure 5, it is specified for the Radial actuation mode (slide-by) at a sensing distance of 0.5 Sn with a Standard Target and a pulse-to-pause ratio of 1:2. Switching Frequency 2y y Sn/2 STANDARD TARGET AC Normal Open BRN (A) Without Ground L1 BLU (2) BRN (B) With Ground (Connector Types Only) y = Width of Standard Target Sn = Sensing Distance d Shielded and Unshielded Styles ECG proximity switches are available in two styles: Shielded and Unshielded. The distinguishing characteristics are illustrated in Figure 6. Shielded (Flush Mounting): This style of switch has the active face essentially even with the threaded end of the switch housing, Figure 6A. The shielded design can be flush mounted in metal with no change in performance characteristics. Unshielded (Non-Flush Mounting): As shown in Figure 613, the active face of the unshielded switch extends well beyond the threaded end of the housing, thus exposing a larger area from which the electromagnetic sensing field can radiate. This style is somewhat side sensitive and, consequently, can not be flush mounted in metal. A metal-free zone about the sensing face is required as described in the Section Mounting and Installation. A. Shielded B. Unshielded ACTIVE FACE Fig. 6 (3) N DC Types DC proximity switches offer the advantages of high switching frequency (up to 1000 Hz in the 8mm size), low voltage drop and minimal leakage current. In addition, their output is compatible with solid state loads, including programmable controllers. They can also be used to directly drive electro-mechanical devices, such as relays, counters, etc. Operation in combination with mechanical contacts is also practical. DC proximity switches do require a separate power supply; however, regulation is not generally necessary. Both shielded and unshielded switch styles are supplied by Philips ECG in 8, 12, 18 and 30 mm sizes with sensing distances of 1.5 to 15 mm, an operating voltage range of 10-30 VDC and a maximum load current capability of 200 mA. Switching configurations include PNP Normal Open, NPN Normal Open, and PNP Complementary. PNP Normal Open (Current Sourcing) - Figure 8: The load is tied to the Negative (common) side of the power supply. The output transistor switches the positive side of the supply to the load. The PNP output function is also known as Current Sourcing since the current for the load is “sourced” by the proximity switch. PNP Normal Open (Current Sourcing) AC Types 130 LOAD BLU When the switch is open, a small leakage current (1.5 mA max.) flows through the load. When closed, there is a voltage drop across the output of up to 8.5 volts. These characteristics must be taken into consideration, especially when several proximity switches are to be connected in series or parallel (see section entitled Series and Parallel Operation). Operation in combination with switches that have mechanical contacts is also feasible. AC proximity switches are not protected against voltage or current overload. Accidental short circuit of the load in the closed (conductive) state will destroy the switch. Also, power should never be applied to the switch in the absence of a load. Protection is provided against RFI (radio frequency interference). Switch Configurations AC proximity switches are 2-terminal, normally open devices which are powered by line voltage. No secondary (external) power source is needed. This feature permits them to be directly substituted for electromechanical limit switches without N L1 (1) GRN/YEL Fig. 7 Fig. 5 LOAD (1) BRN + (4) BLK (3) BLU Fig. 8 LOAD ECG® Relays and Accessories NPN Normal Open (Current Sinking) - Figure 9: The load is tied to the Positive side of the power supply. The output transistor switches the negative (common) supply line to the load. The NPN output function is also known as Current Sinking since the current passes through the load first and “sinks” through the switch. When not sensing a target, the output of both PNP and NPN models is open (non-conductive). It closes (becomes conductive) when a target is sensed. NPN Normal Open (Current Sinking) (1) BRN (4) BLK LOAD recommended. A combination of mechanical contact switches and proximity switches is possible. DC Switches: Series connection of DC proximity switches is shown in Figures 12 and 13 for normally open types with PNP (sourcing) and NPN (sinking) output functions. A voltage drop of up to 2.5 volts occurs with each switch connected in series. Therefore, the voltage available to the load will be reduced by this amount by each switch in the string. Each proximity switch must be capable of supplying the deactivated (“standby”) current of the other switches, as well as the external load current. Proximity switches can be applied in combination with mechanical contact switches. + PNP DC Switches - Series Connection (3) BLU + BRN Fig. 9 + BLK BLU Complementary Normal Open/Normal Closed - Figure 10: DC proximity switches of the complementary type have two outputs: one normally open and another which is normally closed. The two outputs change state simultaneously when a target is detected. Both output transistors are PNP (current sourcing). + BRN BLK BLU Complementary - PNP Normal Open/Normal Closed + BRN BRN BLK + BLK BLU BLU LOAD LOAD + BRN WHT/BLK LOAD BLK Fig. 10 BLU Most electromechanical loads (relays, counters, etc.) will accommodate either PNP or NPN types, providing they are correctly wired. The proper output function must be chosen for solid state loads and programmable controllers. For series and parallel operation, and application in combination with mechanical contacts, see section entitled Series and Parallel Operation. Power Supply: Regulation of supply voltage is not required providing rated switch Operating Voltage is maintained within the limits specified. Supply Voltage Ripple must not exceed 15% of the Operating Voltage. Protective Features: DC proximity switches are protected against accidental polarity reversal, as well as short circuit of the load. They are also immune to RFI (radio frequency interference). Fig. 12 NPN DC Switches - Series Connection + BRN BLK BLU + BRN BLK BLU + BRN BLK Series and Parallel Operation BLU Series Connection AC Switches: Series operation of AC proximity switches is shown in Figure I1. Care must be taken to assure that there is sufficient voltage to the load for it to operate properly. In the closed (conductive) state there is a drop in voltage (loss) across each switch of 8-9 volts at maximum rated current. As the number of switches in series is increased, the loss becomes appreciable and can be enough to prevent the load from operating as it should. It is recommended that no more than four switches be wired in series at 240 VAC and no more than two switches at 120VAC. Series operation below 90 VAC is not AC Switches - Series Connection BRN BLU BRN BLU Fig. 11 L1 + N LOAD LOAD + BRN BLK BLU Fig. 13 Parallel Connection AC Switches: Parallel connection of AC proximity switches is illustrated in Figure 14. The number of switches that can be paralleled is a function of switch leakage current (up to 1.5 mA max. each) and the load impedance. The sum of the leakage currents must be less than the dropout current of the load. It must be noted that when any of the switches connected in parallel is closed, the remaining switches will then function in an “exclusive OR” mode. That is, if another switch senses that it should close after the first one does, the second switch will be prevented from doing so until 100 mS after the first switch opens. When connecting AC proximity switches in parallel with mechanical contacts, potentially damaging transient voltage spikes may be produced when interrupting inductive loads, e.g., contactors, relays, solenoids. To prevent damage to the switch from these voltage spikes, surge suppressors should be used at the source of the spikes. 131 ECG® Relays and Accessories AC Switches – Parallel Connection BRN L1 BLU Shielded and Unshielded LOAD BRN BLU Fig. 14 DC Switches: Proximity switches can be operated in parallel to give an “OR” function. Circuits are shown in Figures 15 and 16 for normally open switches with PNP (sourcing) and NPN (sinking) output functions. The isolation diodes shown are essential with proximity switches that have built-in LED status indicators. Otherwise, all the LEDs will light when one switch closes. Also, without the diodes, each switch must be capable of supplying the deactivated current (“standby current”) of all the switches, as well as the current required by the external load. When connecting DC proximity switches in parallel with mechanical contacts, potentially damaging transient voltage spikes may be produced when interrupting inductive loads. To protect against damage from these voltage spikes and possible false operation, surge suppressors should be used at the source of the spikes. PNP DC Switches - Parallel Connection + BRN Mounting and Installation N + Shielded (Flush Mounting): Shielded proximity switches can be embedded in metal up to the plane of its active face (flush mounted) without operational limitations, Figure 17A. Unshielded (Non-Flush Mounting): The unshielded style of proximity switch requires a metal-free zone around the active face, as illustrated in Figure 17B. This area must be kept free of conductive metals or other materials that possess magnetic properties. The depth should measure no less than the diameter of the switch housing. The diameter of the metal- free zone should be at least three times that of the switch housing. A-Shielded (Flush Mounting) B-Unshielded (Non-Flush Mounting) 3d MIN. 1d MIN. C C METAL Fig. 17 METAL c = Metal Free Zone d = Switch Diameter d Side-By-Side Proximity switches can be mounted side-by-side, Figure 18. However, they must be spaced far enough apart to prevent the electromagnetic sensing field radiated by one switch from affecting operation of the other switch. Shielded switches should be spaced on centers a minimum distance of twice the diameter of the switch housing, Figure 18A. Unshielded switches should be spaced a minimum of three times the diameter of the switch housing, Figure 18B.

When so positioned, a minimum distance of six times the rated sensing distance (Sn) must separate their active faces to preclude possible interaction between the switches. ECG® Relays and Accessories Face-To-Face 6 Sn MIN. Sn = Sensing Distance Fig. 19 Facing Metal Mounting directly opposite a metal surface is another viable option, Figure 20. As shown, the distance between the active face of the proximity switch and the opposing metal surface should be a minimum of three times the rated sensing distance (Sn) of the particular switch. Facing Metal 3 Sn MIN. Sn = Sensing Distance Fig. 20 Installation - Torquing It is recommended that ECG proximity switches be clamped in position using two nuts (and lock washers when specified), one on each side of the mounting surface. If these nuts are overtightened, it is possible to damage the switch housing. Therefore, care should be taken not to exceed the torque values given in the following table: Switch Diameter 8mm (Series 800) Connector Types Cable Types 12mm (Series 1200) DC Types AC Types 18mm (Series 1800) 30mm (Series 3000) Maximum Torque 8 ft. lbs. 4 ft. lbs. 15 ft. lbs. 8 ft. lbs. 35 ft. lbs. 44 ft. lbs. Brackets and Adapters To simplify installation, universal mounting brackets and microswitch adapter brackets are available in most switch sizes. See Accessories section, Page 165. CAUTION: Especially high transient voltages can be introduced by cables which carry high currents for motors, solenoids, clutches, etc. These could cause damage to the proximity switch or activate its short circuit protection. This can be minimized by separating switch wiring from such cables. Terms and Definitions Active Face: The surface of the proximity switch from which the sensing field is radiated.
