Questions about this item

What contact block do I need to pair with the ZCKD21 head for a complete limit switch?

The ZCKD21 is a head assembly designed for use with XCKL or XCKM series bodies; select the matching body and contact block from those families to complete the switch.

Can I reuse my existing XCKL or XCKM body with this new ZCKD21 head?

Yes, the ZCKD21 head is made for XCKL and XCKM bodies, so it mounts directly on those existing assemblies without modification.

How do I verify the ZCKD21 head is operating correctly after installation?

Actuate the roller lever through its 0.47 in travel in both CW and CCW directions; the lever should move smoothly with 1.8 in-lb operating force and return freely when released.
