Installation and Wiring Guide
The D4C-1601 comes pre-wired with a 3-meter SJT(O) cable featuring 4 cores (0.83mm² nominal sectional area, 8.6mm diameter). The cable is terminated with bare end flying leads for easy connection:
Wiring Configuration:
- Common (C): Central connection point
- Normally Open (NO): Contact closes when plunger is depressed
- Normally Closed (NC): Contact opens when plunger is depressed
- Ground/Earth: Safety ground connection
Mounting Considerations:
- Ensure proper alignment with actuating mechanism
- Maintain recommended operating force (11.77N max)
- Allow sufficient over-travel (3mm min) to prevent damage
- Secure cable with strain relief to prevent pull-out
