The Allen Bradley 42EF-R9SCB-G4 is a photoelectric sensor designed for reliable object detection using a transmitted beam with RightSight technology. Operating on a wide voltage range of 21.6 to 264 V AC/DC, this sensor utilizes an infrared light source to provide accurate sensing up to 20 meters. It features dark operate mode, which means the output activates when the beam is interrupted, and comes equipped with a 4-pin DC micro connector for straightforward wiring. This sensor is available through BSP Automation, offering a robust solution for applications requiring precise, long-range detection in various industrial environments.
