Resetting Short-Circuit Protection Before the short-circuit protection can be reset, the short must be repaired. We recommend turning the power off before repairing the short. If this approach is taken, no further action is required to reset the short-circuit protection. If the short must be repaired with power on, the following resetting steps are required: For NO sensors, the target must be removed to reset the short-circuit protection. For NC sensors, the target must be presented then removed to reset the short-circuit protection. 6 E2E 2-WIRE AC E2E 2-WIRE AC Engineering Data J OPERATING RANGE (TYPICAL) Shielded Models Sensing distance X (mm) Sensing distance X (mm) E2E-XjYj-N E2Ej--X10j E2Ej-X2j E2Ej-X1R5j E2Ej--X5j Y (mm) Y (mm) Unshielded Models Sensing distance X (mm) Sensing distance X (mm) E2E-XjMYj-N E2Ej-X5Mj E2Ej-X18Mj E2Ej-X10Mj E2Ej-X2Mj Y (mm) Y (mm) J LEAKAGE CURRENT (TYPICAL) Proximity Sensor (when OFF) E2E-XjYj-53-US Leakage current (mA) Leakage current (mA) E2E-XjYj-N Protective resistance AC power supply Supply voltage (V) Supply voltage (V) 7 E2E 2-WIRE AC E2E 2-WIRE AC J RESIDUAL OUTPUT VOLTAGE (TYPICAL) E2E-XjYj-N Residual output voltage Proximity Sensor 24 VAC Residual load voltage Proximity Sensor 100 VAC Residual load voltage Load current (mA) Residual load voltage (V) Residual output voltage Residual load voltage (V) Residual load voltage (V) Residual output voltage Proximity Sensor 200 VAC Residual load voltage Load current (mA) Load current (mA) J SENSING DISTANCE VS.

J INSTALLATION Power Reset Time The Proximity Sensor is ready to operate within 100 ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. Power OFF The Proximity Sensor may output a pulse signal when it is turned off. Therefore, it is recommended to turn off the load before turning off the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Sensing Target Metal Coating: The sensing distances of the Proximity Sensor vary with the metal coating on sensing targets. J WIRING High-tension Lines Wiring through Metal Conduit If there is a power or high-tension line near the cord of the Proximity Sensor, wire the cord through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. 15 Diameter Tractive force 4 mm dia. max. 30 N max. 4 mm dia. min. 50 N max. J MOUNTING The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, or the Proximity Sensor may be damaged or lose its water-resistance. J ENVIRONMENT Water Resistance Do not use the Proximity Sensor underwater, outdoors, or in the rain. Operating Environment Be sure to use the Proximity Sensor within its operating ambient temperature range and do not use the Proximity Sensor outdoors to maintain its reliability and life expectancy. Although the Proximity Sensor is water resistant, a cover to protect the Proximity Sensor from water or water soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic, and concentrated sulfuric acid gases). E2E 2-WIRE AC E2E 2-WIRE AC J CONNECTING LOAD TO AC 2-WIRE SENSOR Refer to the following before using AC or DC 2-wire Proximity Sensors. Surge Protection Although the Proximity Sensor has a surge absorption circuit, if there is any machine that has a large surge current (e.g., a motor or welding machine) near the Proximity Sensor, connect a surge absorber to the machine. Leakage Current When it is OFF, the Proximity Sensor has leakage current. Refer to Leakage Current Characteristics. In this case, the load is imposed with a small voltage and the load may not be reset. Before using the Proximity Sensor, make sure that this voltage is less than the load reset voltage. The AC 2-wire Proximity Sensor cannot be connected to any card-lift-off relay (e.g., the G2A) because contact vibration of the relay will be caused by the leakage current and the life of the relay will be shortened. Countermeasures Against Leakage Current AC 2-wire Models Connect a bleeder resistor as the bypass for the leakage current so that the current flowing into the load will be less than the load reset current. As shown in the following diagram, connect the bleeder resistor so that the current flowing into the Proximity Sensor will be 10 mA minimum and the residual voltage imposed on the load will be less than the load reset voltage. Load Bleeder resistor R VAC power supply VS Refer to the following to calculate the bleeder resistance and the allowable power of the bleeder resistor. R ≦ VS/(10 -- I) (kΩ) P > VS2/R (mW) P: The allowable power of the bleeder resistor. (The actual power capacity of the bleeder resistor must be at least a few times as large as the allowable power of the bleeder resistor.) I: Load current (mA) The following resistors are recommended. 100 VAC (supply voltage): A resistor with a resistance of 10 kΩ maximum and an allowable power of 3 W minimum 200 VAC (supply voltage): A resistor with a resistance of 20 kΩ maximum and an allowable power of 10 W minimum If these resistors generate excessive heat, use a resistor with a resistance of 10 kΩ maximum and an allowable power of 5 W minimum at 100 VAC and a resistor with a resistance of 20 kΩ maximum and an allowable power of 10 W minimum at 200 VAC instead. J PRECAUTIONS FOR AC 2-WIRE PROXIMITY SENSORS IN OPERATION Connector Model Connection type AC 2-wire AND (serial connection) Method Description If 100 or 200 VAC is imposed on the Proximity Sensors, VL (i.e., the voltage imposed on the load) will be obtained from the following. Incorrect Load VL = VS -- (residual voltage x no. of Proximity Sensors) (V) Therefore, if VL is lower than the load operating voltage, the load will not operate. Correct Load A maximum of three Proximity Sensors can be connected in series provided that the supply voltage is 100 V minimum. Load Vs ≧ 100 V 16 E2E 2-WIRE AC E2E 2-WIRE AC J PRECAUTIONS FOR AC 2-WIRE PROXIMITY SENSORS IN OPERATION, CONTINUED Model Connection type AC 2-wire OR (parallel connection) Method Description In principle, more than two Proximity Sensors cannot be connected in parallel. Incorrect A Load B Provided that Proximity Sensor A does not operate with Proximity Sensor B simultaneously and there is no need to keep the load operating continuously, the Proximity Sensors can be connected in parallel. In this case, however, due to the total leakage current of the Proximity Sensors, the load may not reset properly. Correct A Load B VAC power supply VS It is not possible to keep the load operating continuously with Proximity Sensors A and B in simultaneous operation to sense sensing objects due to the following reason. When Proximity Sensor A is ON, the voltage imposed on Proximity Sensor A will drop to approximately 10 V and the load current flows into Proximity Sensor A, and when one of the sensing objects is close to Proximity Sensor B, Proximity Sensor B will not operate because the voltage imposed on Proximity Sensor B is 10 V, which is too low. When Proximity Sensor A is OFF, the voltage imposed on Proximity Sensor B will reach the supply voltage and Proximity Sensor B will be ON. Then, Proximity Sensor A as well as Proximity Sensor B will be OFF for approximately 10 ms, which resets the load for an instant. To prevent the instantaneous resetting of the load, use a relay as shown on the left. NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
