22 mm Red E-Stop Operator

The Eaton M22-PV is a maintained emergency stop pushbutton operator designed for industrial safety circuits. It features a 45 mm red mushroom head with a metal base and plastic head material. The unit carries a silver bezel and includes a contact block mounting adapter for direct installation. Rated IP67 and IP69K, it withstands high-pressure washdown and temporary immersion.

Suited for Safety Panel Builders

This operator fits panels requiring a 22 mm mounting hole and maintained actuation that stays latched until manually reset. The NEMA 1, 2, 3, 4, 4X and 13 ratings support indoor and outdoor enclosures exposed to dust, water and corrosion. Buyers needing momentary action or a different head diameter should look at alternative operator types.

45 mm Mushroom Head Diameter

The 45 mm head size determines whether the device meets specific safety standards for actuation force and visibility in the target application. Combined with the 22 mm mounting thread, this dimension dictates compatibility with existing panel cutouts and legend plates. Verify the required head diameter against the machine safety specification before ordering.

Questions about this item

Will the 22 mm mounting fit the existing panel cut-outs on my older control cabinet?

The operator uses a standard 22 mm mounting diameter compatible with legacy panels; the metal bezel and silver finish match traditional industrial aesthetics.

How can I verify the IP67 and IP69K seals are effective after installation?

Press the red mushroom head firmly — it should latch in the maintained position; then inspect the gasket seating and run a low-pressure water test to confirm ingress protection.

Does the package include the contact blocks or must I order them separately?

The box contains the pushbutton operator with a contact block mounting adapter; contact blocks themselves are sold separately.
