42GRU-9202-QD | Allen-Bradley Photoelectric Sensor, AC/DC, 5-Pin Mini QD

The 42GRU-9202-QD is a polarized retro-reflective photoelectric sensor used for precise object detection and proximity sensing. It detects objects that interrupt the beam reflected from a dedicated reflector, ensuring high reliability in industrial applications. It’s commonly used in conveyor systems, material handling, and packaging lines. The sensor ensures fast and accurate detection regardless of background conditions. Its polarized optics help avoid false detections from shiny surfaces.

The sensor uses a 5-pin Mini QD (Quick Disconnect) connector with M12 thread size. This allows fast and secure installation, minimizing wiring errors and downtime. M12 connectors are standardized in the industry, making replacement and wiring convenient. The 5 pins typically support power, ground, and signal lines. Quick-disconnect design supports fast maintenance or swap-out.

Yes, it supports both Light On and Dark On switching types. This enables the user to choose whether the output activates when the beam is received or interrupted. Such flexibility is essential for various sensing logic in control applications. Switching mode selection may be done via internal settings or wiring configuration. It enhances control system design flexibility.

It operates in polarized retro-reflective mode, meaning the sensor emits a red LED beam that reflects off a specialized reflector. Only correctly polarized light is received back, ensuring accuracy by filtering out unwanted reflections. This setup is excellent for detecting shiny or glossy objects. The polarized approach also avoids false triggers caused by environmental lighting. It's highly reliable in dynamic industrial settings.

Yes, the Allen-Bradley 42GRU-9202-QD is currently in production and available through Rockwell Automation or authorized distributors. However, as with all automation components, it's recommended to check the lifecycle status regularly. Distributors often provide availability updates or migration paths if the sensor is nearing obsolescence. The sensor continues to be widely used in automation systems. For ongoing projects, it's advisable to verify continuity of supply.
