Allen-Bradley 802M-AY20 Limit Switch Pre-Wired

Allen-Bradley 802M-AY20 is a pre-wired, factory-sealed limit switch from the 802M family, supplied as a complete lever-type device with spring-return action for dependable end-of-travel sensing in industrial equipment. This 2-circuit configuration supports both clockwise and counterclockwise actuation (CW/CCW) and arrives with a 20-foot (6.1 m) extended cable, simplifying field wiring and reducing harnessing requirements. The AY20 suffix designates the 20 ft cable length, making it a plug-and-play option for machines that require a ready-to-wire sensing solution. The unit’s lever-type operating head and sealed construction are intended for rugged industrial environments, delivering reliable position sensing for control circuits, sequencing, or safety interlock applications where a compact form factor matters. As a factory-sealed, pre-wired assembly, it minimizes installation time and helps protect the connections from dust and debris while maintaining consistent switching performance. In typical installations, technicians mount the switch to a fixed frame and use the lever to actuate the internal contacts from either side, benefiting from the dual-circuit arrangement to monitor two discrete signals with one compact device.
