Allen-Bradley 801 ASG17 Limit Switch

The Allen-Bradley 801-ASG17 is a general-purpose limit switch with a roller-lever actuator, designed for dependable end-of-travel sensing in industrial machinery. It uses a slow-action, spring-return mechanism inside a Type 2 housing and Arrangement G contacts, providing reliable actuation and reset in tight spaces. The switch is designed for AC and DC operation up to 600 V and, in verified listings, demonstrates a representative contact rating of 6 A at 120 V. Mechanical data include a maximum operating force of 22.25 N (5.0 lb) and a travel-to-operate of up to 25 degrees, with a minimum overtravel of 30 degrees to tolerate mounting variations. The roller lever enables consistent engagement with moving parts, making it suitable for conveyors, guards, and other equipment where compact, repeatable limit sensing is essential. This model is part of Allen-Bradley’s 801 series, offering a compact, Type 2-enclosed switch that supports rugged industrial environments and repeated cycling across typical manufacturing line applications.
