Designed for precise detection, the Allen Bradley 42SRU-6203-QD is a polarized retroreflective photoelectric sensor. Operating within a rated voltage range of 10 to 30 V DC, this sensor draws a supply current of 35 mA during functioning. The unit boasts a sensing distance from 50.8 mm (2 inches) up to 3 m (10 feet), optimized when utilizing a 76 mm (3 inch) reflector for enhanced performance.

The output configuration is activated when in darkness, which is ideal for specific applications that require signaling in low-light conditions. This sensor supports both NPN and PNP output types, providing flexibility in connecting to various control systems. With a response time of just 1 ms, it delivers prompt detection, while a leakage current of 1 µA ensures low power loss during idle periods.

Connection is facilitated through a 4-pin DC micro QD, making installation straightforward. The housing is constructed from Noryl, offering durability, while the lens is made of acrylic, ensuring clarity and reliability in detecting reflective surfaces. Overall, the 42SRU-6203-QD sensor delivers robust performance for automation needs.
