Detection Switch D3C 45 Engineering Data ■ Contact Specifications Item ■ Mounting All D3C switches may be panel mounted using M1.6 mounting screws with plane washers or spring washers to securely mount the switch. Tighten the screws to a torque of 4.9 to 9.8 x 10-2 N·m. Specification Specification Slide Material Silver plated Minimum applicable load (see note) 1 mA at 5 VDC M1.6 tap 4±0.1 Note: Minimum applicable loads are indicated by N standard reference values. This value represents the failure rate at a 60% (λ60) reliability level (JIS C5003). 5.7±0.1 ■ PCB Layout (reference) The equation λ60=0.5 x 10-6/operations indicates that a failure rate of 1/2,000,000 operations can be expected at a reliability level of 60%. 2.54 ■ Switching Timing Non-shorting Model (2) (NC) FP OP1 1.6 dia Three, 1 dia. hole 2.54 Shorting Model OP2 TTP (2) (NC) FP (1) (3) (NO) OP1 4.2 OP2 TTP (1) (3) (NO) 8 ■ Contact Form SPDT NO COM NC (3) (1) (2) Dimensions Note: 1.

Precautions Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide, “Snap Action Switches, Technical Information” for correct use. ■ Correct Use ■ Cautions Mounting Terminal Connection Turn off the power supply before mounting or removing the switch, wiring or performing maintenance or inspection. Failure to do so may result in electric shock or burning. When soldering the lead wire to the terminals, first bind the lead wire to the terminal and then apply the 60(Sn):40(Pb) solder to the terminals. Complete soldering within 5s at a soldering iron temperature of 260°C. Soldering at a temperature exceeding 260°C, soldering for more than 5 s, or repeated soldering will degrade the switch characteristics. Mount the switch onto a flat surface. Mounting on an uneven surface may cause deformation of the switch, resulting in faulty operation or breakage in the housing. Application of Operation Force to the Lever Apply operation forces to the lever in its operating direction. Applying operating force to the lever in any other directions will damage the switch or cause malfunction. Incorrect Incorrect When soldering the lead wire to the PCB terminal, pay careful attention so that the flux and solder liquid level does not exceed the PCB level. It is also recommended that you apply flux guard to the mounting surface of the switch. Incorrect Switch mounting surface Correct Mounting Plate Use materials other than ABS or polycarbonate for the mounting plate. Since grease is used within the switch, cracks may be caused if grease from the switch comes in contact with such materials. Using Microloads Voltage (V) Using a model for ordinary loads to switch microloads may result in faulty operation. Instead, use the models that are designed for microloads and that operate in the following range; 30 0.16 mA 100 mA 24 Operating range 12 Inoperable range 5 1mA 0 0.1 1 10 100 1,000 Current (mA) However, even when using microload models within the operating range shown above, if inrush current or inductive voltage spikes occur when the contact is opened or closed, then contact wear may increase and so decrease the service life. Therefore, insert a contact protection circuit where necessary.
