The Allen-Bradley 42EF-B1MPBE-F4 is a high-performance photoelectric sensor from the RightSight™ series. This polarized retroreflective sensor is engineered for reliable object detection in demanding industrial environments. Its compact, rectangular housing allows for flexible mounting in space-constrained applications. The visible red light source simplifies alignment and setup, while the polarized filter ensures accurate detection of shiny or reflective objects, minimizing false triggers. Featuring a robust IP67/IP69K enclosure rating and a standard 4-pin M12 connector, this sensor provides a durable and easy-to-integrate solution for packaging, material handling, and assembly automation tasks.
