Allen-Bradley 802T-A2D Limit Switch

Allen-Bradley 802T-A2D is a two-circuit limit switch in Rockwell Automation’s 802T family, designed for end-of-travel sensing in industrial equipment. This standard, non plug-in device uses a rotary lever actuator and a compact body with a standard mounting footprint, enabling straightforward replacement in legacy Allen-Bradley installations and reliable actuation in confined spaces. The A2D configuration provides two independent circuits for simple control or interlock functions, and the switch is rated for up to 600 V AC and 10 A maximum, making it suitable for common factory automation control circuits. Typical applications include detecting part presence or end stops on conveyors and presses, triggering downstream logic, and serving as a durable limit sensor in automation lines where robust mechanical action and easy wiring are required. According to widely cited catalogs, 802T devices are offered in left- and right-hand variants and a variety of actuators, with the A2D model continuing that tradition to support reliable, maintenance-friendly sensing across rugged industrial environments.
