Allen-Bradley 42EF-P2MPB-F4 Photoswitch RightSight Sensor

The Allen-Bradley 42EF-P2MPB-F4 PHOTOSWITCH RightSight is a polarized retroreflective photoelectric sensor designed for reliable object detection along conveyors, packaging lines, and automated equipment. It uses a red visible-light beam and provides two complementary LO/DO outputs in a DC Source (PNP) configuration, with IO-Link enabled for straightforward integration. Key specs include a 3 m maximum sensing distance for retroreflective targets, a 1 ms response time, and a 10.8–30 V DC supply range. The device ships with a 4-pin DC Micro QD connector on a 152 mm (6 in) pigtail and employs a Mindel™ housing with a Udel™ cover, rated IP67 for robust washdown environments and compatibility with 4X/NEMA 4X, 6P protection. There is no sensitivity adjustment, and the unit is built to withstand demanding industrial conditions with operating temperatures from -25 to 70 °C, 30 g shock, and 10–55 Hz vibration. Its compact footprint measures approximately 46.7 mm in height, 34.5 mm in length, and 27 mm in width, with a sensing spot of about 83.8 mm at 3 m. The RightSight family centers on polarized retroreflective sensing, red illumination, and DC micro-connectivity, making this model a solid choice for reliable detection of reflective targets in space-constrained automation applications.
