Emergency Stop Button 22 mm

The Schneider Electric ZB5AT84TQ is a maintained push–pull emergency stop push-button designed for industrial machinery panels. Its 40 mm red mushroom head provides a clear, tactile target for operators who must halt equipment quickly in hazardous situations.

Mounting Diameter 22 mm

The single specification that determines fit is the 22 mm panel cut-out. This size matches standard industrial control stations, so the device installs directly without adapters or enlarged holes.

Sealed to IP 69K

The plastic bezel and operator meet NEMA 13, 4X and IP 66, 67, 69, 69K ratings, resisting high-pressure wash-down and dust ingress. No active cooling or moving seals are used, so the unit adds no audible noise and draws no electrical power in normal operation.

Questions about this item

What does the 22 mm mounting diameter mean when installing this emergency stop button?

The 22 mm cut-out is the standard industrial size for panel mounting. You drill a 22 mm hole, insert the operator through the front, and secure it from behind with the supplied locking nut.

How do the IP66, IP67, IP69 and IP69K ratings limit where the button can be used?

These ratings confirm protection against powerful water jets, temporary immersion, and high-pressure, high-temperature wash-downs. The button is suitable for food-processing, outdoor and heavy-wash environments.

What panel thickness and clearance does the 40 mm mushroom head need to fit?

The 22 mm mounting hole fits panels up to the manufacturer's specified maximum thickness. Behind the panel, allow enough depth for the contact blocks and wiring; the 40 mm mushroom head projects above the surface for easy actuation.
