Allen-Bradley 800MR-JX5B Push Button With Contact Block

Allen-Bradley 800MR-JX5B is a 22.5 mm round push button from the 800MR family, featuring a non-illuminated plastic operator with a grey bezel for rugged control-panel use. This unit ships with an 800M-XA contact block that provides a 1 normally open / 1 normally closed arrangement and uses Quick Connect terminals for wiring. The block termination supports two 2.79 x 0.81 mm push-on connectors or a single 6.35 x 0.81 mm push-on connector (stab), offering flexible wiring options in panel installations. The 800MR series is designed for momentary operation, so the contacts return to their resting state when the button is released, which is ideal for start/stop, reset, or fault-clearing actions in industrial machines, conveyors, and equipment control panels. With its 22.5 mm footprint, it fits standard panel cutouts used for 800M/XA assemblies and provides a compact, reliable control point in harsh manufacturing environments.
