Allen-Bradley 42SRP-6024 Photoelectric Sensor

Allen-Bradley PHOTOSWITCH 42SRP-6024 is a compact 28 mm-diameter fixed-focus diffuse photoelectric sensor from the 6000 Series, designed for close-range part detection with a nominal sensing distance of 28 mm (1.1 in). It operates on a broad 20–132 V AC/DC supply and ships with a 3 m (9.8 ft) cable for flexible mounting on conveyors or packaging lines, while using a visible red 660 nm LED to emit the sensing beam. The sensor detects targets based on reflected light in diffuse, fixed-focus mode, and its light-Operate output energizes when the target reflects sufficient light, making it suitable for presence checks of small or flat parts in routine manufacturing processes. With a 28 mm body and fixed-focus optics, the PHOTOSWITCH 42SRP-6024 offers a robust, industrial-grade solution that integrates with standard PLC inputs and remains reliable in typical production environments where space is limited and repeatable detection is required.
