EMAS P1C400E72 Mushroom Style Emergency Button 72mm (1 x N.C)

P Series Plastic 1 Hole CPDE72+C4CK (NC) Grey-Black Control Box The P1C400E72 puts a large 72mm mushroom-head emergency button in a ready-to-mount control box, sized for simple palm or foot operation where a standard 22mm e-stop button would be too small or fiddly to hit reliably. Press to stop, twist the head to release — no separate box and button to source and assemble. 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.

It latches on depression — rotate the mushroom head to release it and restore the circuit. 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. What cable entry does it use? M20 knockouts for easy gland or conduit installation. Why choose a 72mm mushroom head over a standard 22mm e-stop? The larger head suits palm or foot operation, useful where an operator needs to hit the stop quickly and reliably without precisely targeting a smaller button.
