The 42SRU-6205-QD photoelectric sensor, manufactured by Allen Bradley, is part of the Photoswitch series. This sensor operates using polarized retroreflective technology, allowing it to accurately detect objects within a range of 50.8 mm to 3 meters. It is versatile in terms of voltage, operating efficiently at both 20 to 132 volts for alternating current (AC) and direct current (DC).

The sensor's output configuration is based on a power MOSFET, specifically designed to function in a dark operate mode. This means it activates when an object interrupts the beam of light. The light source utilized is a red LED, known for its visibility and performance in various environments.

In addition to its sensing capabilities, the 42SRU-6205-QD boasts a quick response time, which is 12 milliseconds for AC and as fast as 5 milliseconds for DC operations. This rapid response rate enhances the sensor's reliability in automation applications where timing is crucial. The load current is rated at 300 mA, making it capable of driving various control applications effectively.

The sensor connects through a 4-pin AC micro quick disconnect type, which facilitates simple and efficient installation setup. Overall, the 42SRU-6205-QD photoelectric sensor offers reliable performance and is well-suited for a variety of sensing applications.
