Allen-Bradley 800MR-12HX2B Rotary Selector Switch

Allen-Bradley 800MR-12HX2B is a rotary selector switch that serves as a compact operator interface in industrial control panels, pairing the 800MR rotary unit with an 800M-XA contact block to provide a discrete, wire-ready selector function. The included 800M-XA contact block offers 1 normally open and 1 normally closed contact (1NO/1NC) and uses Quick Connect terminals for straightforward wiring. This 800M-XA block is the standard contact block used with 800MR assemblies, aligning with Bulletin 800MR configurations. In line with the 800MR family, the assemblies are available in oil-tight variants. The contact block carries a maximum voltage rating of 300 VAC, making it suitable for common control circuits and interlock applications. Together, the 800MR switch and 800M-XA block enable operators to select among discrete control states and generate clean, isolated signals for a PLC or interlock logic, all while maintaining a compact footprint in the panel.
