P Series Plastic 1 Hole CPDM72K+C4CK (NC) Grey-Black Control Box
The P1C400M72 is the momentary counterpart to EMAS's mushroom-head e-stop box — same large 72mm palm/foot-operable head, but spring-return rather than latching, so it makes contact only while pressed. Useful for jog, test, or reset functions where you don't want the button staying engaged.
M20 knockouts for easy installation. Predrilled rear mounted holes which do not compromise the IP65 rating.
Complete with one normally closed contact fitted. Accepts additional contacts C3CK (normally open) and C4CK (normally closed). Contacts clip to the rear of the mounting box to provide secure actuation.

Frequently Asked Questions
What's the difference between this and the P1C400E72?
This P1C400M72 is momentary — spring-return, making contact only while held down. Our P1C400E72 is latching (an e-stop style action), staying engaged after release until manually twisted to reset. Choose based on whether you need a maintained stop or a momentary function.
Can I add more contacts?
Yes — it accepts additional C3CK (N.O.) and C4CK (N.C.) contact blocks, which clip to the rear of the box for secure actuation.
Is this suitable for outdoor or washdown installation?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
Why choose a 72mm mushroom head for a momentary function?
The larger head suits palm or foot operation, useful for jog, test, or reset functions an operator needs to hit quickly without precisely targeting a small button.
Industry Applications
- Machine tools & production equipment — palm-operated jog, test, or reset functions
- Foot-accessible momentary controls — equipment where hands may be occupied
- Panel refurbishment — ready-to-install momentary station replacing separate box and button sourcing
