Pushbutton operator · 22.5 mm red STOP · through-the-door non-illuminated · Eaton M22-DZ-R-GB0

What this product is for

This is a 22.5 mm through-the-door pushbutton operator for STOP functions on industrial control panels, enclosures, and machine interfaces. It is used where the operator mounts on the door and actuates the contact assembly behind the panel.

Use for

Use for machine stop stations, control panel doors, OEM equipment, and industrial or light commercial control assemblies that require a red STOP operator. Commonly used where a non-illuminated momentary operator is paired with the appropriate M22 contact block arrangement.

Avoid for

Avoid using this as a complete emergency stop assembly unless the full device configuration, contact elements, and code requirements are confirmed. Also avoid where illumination, maintained action, or a different operator style is required.

Best for

Best for electricians, panel builders, and maintenance teams standardizing on Eaton RMQ-Titan M22 22.5 mm pilot devices. It is a practical choice when a through-the-door operator is needed instead of a standard front-of-panel pushbutton body.

Installed in

Typically installed in control panel doors, machine enclosures, operator stations, and industrial cabinets with a 22.5 mm mounting opening. The pushrod is commonly cut to suit door depth and hardware layout; actual fit depends on enclosure construction and the selected contact blocks.

Why this product exists

Through-the-door operators let the installer place the actuator on the enclosure door while the switching elements remain inside the panel. This helps maintain a clean operator layout and supports safer access to control functions from the exterior of the enclosure.

Compared with similar products

Compared with a standard flush pushbutton operator, this M22-DZ version is intended for through-the-door applications. It is non-illuminated and marked STOP, making it suitable for stop-command duty where visibility comes from the red actuator rather than an indicator lamp. If you need indication, maintained action, or a complete assembled device, choose the matching M22 variant and contact blocks accordingly.
