Overview
The Allen-Bradley 802B-PSABBSX is a precision compact limit switch designed for electrical control systems requiring accurate position sensing. This Allen-Bradley 802B-PSABBSX model combines proven reliability with a robust metal enclosure and standardized configuration, making it ideal for machinery motion control and emergency stop circuits. The switch responds to predetermined cam or component motion to establish system limits and protect equipment.
