Allen-Bradley 42KL-RLB-F4 Transmitted Beam Receiver Sensor is the receiver component of a MiniSight through-beam photoelectric pair, designed to detect interruptions in a paired infrared beam. It operates on 10.8–30 V DC with LO or DO selectable, and uses a 4-pin DC Micro connector on a 152 mm (6 in) pigtail. Capable of sensing distances up to 30 meters, this compact receiver complements the transmitter in long-range automation setups.
