Polarized retroreflective sensing 4-pin DC Micro QD connector 10-30V DC operation 3m sensing distance NPN/PNP dual output Dark Operate mode

Product description

The Allen Bradley 42SRU-6203-QD is a Series 6000 polarized retroreflective photoelectric sensor featuring a 4-pin DC micro QD connector for quick and reliable connections. It operates on a 10-30V DC voltage range with a 35mA current draw. This sensor offers a sensing distance of up to 3 meters (10 ft) and supports both NPN and PNP outputs. It is designed for 'Dark Operate' mode.

This sensor is ideal for automation applications requiring fast sensor changes and robust connections in demanding industrial environments. Its polarized retroreflective technology ensures accurate detection by minimizing false triggering from reflective surfaces. The QD connector simplifies maintenance and reduces downtime, making it suitable for industries like automotive, packaging, and general manufacturing.
