Allen-Bradley 42SRP-6003 Photoelectric Sensor

Allen-Bradley 42SRP-6003 Photoelectric Sensor is a compact diffuse-reflective device from the PHOTOSWITCH 6000 Series designed for short-range object detection. It operates on a 10–30 V DC supply and uses a standard diffuse sensing mode to detect objects by reflections from the target, with a maximum sensing distance of up to 0.76 meters (30 inches) on a white-paper target. The sensor features a 4-pin Micro Quick Disconnect (QD) connector for quick wiring, and the 42SRP-6003 variant is documented as dark-operate in its default configuration. It uses near-infrared illumination (approximately 880 nm) for reliable sensing of common industrial parts. As a 6000 Series diffuse sensor, it suits small-to-mid-size part detection on conveyors, fixtures, and basic pick-and-place tasks where reflected-light sensing is appropriate. The quick-disconnect suffix, 42SRP-6003-QD, denotes the pre-wired version of the same sensing characteristics in a ready-to-mount form.
