Bulletin 802M

The Allen-Bradley Bulletin 802M is a family of factory-sealed and standard-sealed heavy-duty limit switches designed for industrial position-sensing and machine-guarding applications. Products in this family span complete switches, head-only assemblies, and mounting adaptor kits, covering configurations such as rotary lever, spring-return lever, push rod, and sequential actuator styles — as seen across popular models like the 802M-ATY5 (complete switch, rotary lever spring-return), 802M-CX (head-only, side push rod), 802M-ASX (head-only, rotary lever sequential), and 802M-N1 (standard sealed rear mounting adaptor kit). Catalog numbers follow a structured code: the prefix (802M) identifies the sealed limit switch series; subsequent characters encode the actuator/head type, contact block configuration (D2 = 1 N.C., A = 1 N.O.–1 N.C., A4 = 2 N.C., G1 = 2 N.O.–2 N.C.), and optional suffix codes for low-voltage PenTUFF (V) or Class I Div 2 explosion-protected (F) contacts. For full electrical ratings, environmental ratings, and wiring diagrams, consult the Allen-Bradley Bulletin 802M Limit Switch Technical Data (800-TD009).
