Overview
The Fuji Electric AR22M0R is a 22mm-diameter pushbutton switch engineered for demanding industrial environments. This black mushroom-head operator combines robust construction with field-proven reliability, making it ideal for control panels, machine tools, and instrumentation applications. The AR22 Series features a 22mm diameter illuminated pushbutton with emergency stop capability.
Key Features
- Toolless Mounting: The AR22 Series uses a release arm with a wedge mechanism that enables you to mount or remove the operator and contact block without using any tools.
- Dual Panel Cutout Compatibility: The improved locking nut is capable of mounting the operator in both 22.3mm and 25.5mm diameter panel cutout holes.
- Panel-Agnostic Installation: When fitting to a panel, you can ignore the thickness.
- Modular Contact Block Design: Snap-on mounting allows replacement of the contact block and transformer unit with simple screwdriver access, without special tools.
- Global Certifications: The AR22 series is rated for UL, CSA, CE, CCC and TUV.
