22 mm Emergency Stop Button

The Schneider Electric XB4BT842 is a 22 mm chromium-plated metal emergency stop push button with a single normally closed contact. It belongs to the Harmony XB4 range built for industrial control panels. The snap-fit head and body lock onto a fully metal mounting collar with one screw. The red mushroom head provides clear identification for safety circuits.

Suited for safety circuits on machines

This operator fits panels cut to 22 mm and targets machine builders in automotive, textile and timber sectors who need a robust e-stop. The shake-proof screw terminals suit both low-load signalling and high-power contact duties. Buyers who require a normally open contact block or a different actuator style should select another reference.

22 mm mounting diameter decides fit

The 22 mm cut-out is the single dimension that determines whether this unit matches the panel. The metal collar and snap-fit assembly allow fast, secure installation without periodic retightening. Verify the panel aperture before ordering.

Questions about this item

How deep is the 22 mm mounting hole behind the panel?

The 22 mm diameter fits standard panels; exact behind-panel depth depends on the contact block and collar you choose.

Does the red mushroom head stay cool during continuous operation?

The operator is a mechanical switch with no internal heating element, so it does not generate heat itself.

Which contact block and metal mounting collar must I already have to complete the XB4BT842?

You need a Harmony XB4 1NC contact block and the matching chromium-plated metal collar for secure snap-fit mounting.
