Allen-Bradley 802M-K1Y5 Limit Switch

The Allen-Bradley 802M-K1Y5 is a factory-sealed, pre-wired limit switch from Rockwell Automation designed for end-of-travel detection in demanding industrial environments. This complete switch uses a horizontal, side-push roller actuator for reliable side engagement and ships with a 1.52 m (5 ft) straight-through STO cable, simplifying installation and wiring. It is a two-circuit device, providing two independent contact circuits for parallel or separate control paths, and it is rated for up to 600 V AC to suit a wide range of machinery standards. The model’s “K1Y5” suffix identifies the horizontal side-push roller configuration with factory wiring, aligning with standard 802M mounting practices for quick retrofit or new-machine setups. Common applications include conveyors, packaging lines, machine tools, and other automated equipment where robust, pre-wired limit-switch performance is essential for precise position sensing and safe machine stop or control logic. This 802M family part combines rugged construction with ready-to-use wiring, reducing field assembly time while delivering reliable actuation and two-circuit versatility in a compact, standard-body form factor.
