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
Frequently Asked Questions (FAQ)
What is the difference between D4C-1601 and D4C1601?
The D4C-1601 and D4C1601 are identical products. The hyphen is often omitted in part number references, but both refer to the same compact enclosed vertical limit switch with pin plunger.
Is the D4C-1601 suitable for outdoor applications?
With its IP67 rating, the D4C-1601 is protected against dust ingress and temporary immersion in water (up to 1 meter for 30 minutes). However, for continuous outdoor exposure, additional protection from UV radiation and extreme weather conditions is recommended.
What is the expected service life of the D4C-1601?
The switch is rated for a minimum of 200,000 electrical operations (at 5A, 125VAC) and 10 million mechanical operations under normal operating conditions. Actual service life depends on operating environment, load conditions, and maintenance practices.
Can the D4C-1601 be used with PLC systems?
Yes, the D4C-1601 is compatible with most PLC input modules. The SPDT configuration allows connection to both sinking and sourcing PLC inputs. Always verify voltage and current compatibility with your specific PLC model.
