Allen-Bradley 42EF-P2RFB-A2 RightSight Photoelectric Sensor

The Allen-Bradley 42EF-P2RFB-A2 (42EF-P2RFB-A2) is a photoelectric sensor from the Bulletin 42EF RightSight product family designed for reliable object detection and presence sensing across automated industrial systems. Engineered for seamless integration into Rockwell Automation architectures, this sensor serves machinery such as packaging lines, material handling systems, sorting conveyors, and assembly equipment. Within these operating environments, the device detects the presence, passage, or alignment of parts and packaging materials, relaying accurate status signals to programmable logic controllers and higher-level control networks. Built to withstand demanding factory conditions, the housing protects the internal optical elements and electronic circuitry from dust, mechanical vibration, and common ambient contaminants. The unit features standard mounting configurations and pre-wired connection leads for simplified field installation, wiring, and replacement during routine maintenance. With a recorded shipping weight of 10 kg, this component delivers stable optical performance, high reliability, and responsive detection to minimize operational downtime and maintain continuous process throughput in modern production facilities.
