Perfect for automation project

Used this for a small conveyor belt counter. The range is accurate and the separate emitter/receiver design makes alignment easy.

Reliable detection

No false triggers so far. I am using it with a PLC and the switching speed is sufficient for my application.

Great for robotics

Integrated this into a mobile robot for obstacle avoidance. The infrared beam is stable and not easily affected by ambient light.

5 FAQ

Q: Is this sensor suitable for outdoor use?

A: It has an IP65 rating which protects against dust and water jets, but direct sunlight may interfere with the infrared beam.

Q: Does this come with mounting brackets?

A: Yes, the package includes basic mounting hardware and screws for securing the emitter and receiver units.

Q: Can I extend the cable length?

A: Yes, you can extend the cables using shielded wire to prevent noise interference, especially for long distances.

Q: Can this sensor be directly connected to an Arduino?

A: Yes, but ensure you match the voltage levels. The sensor operates on 6-36V, so you may need a logic level converter for 5V Arduino pins.

Q: What is the exact wiring color code?

A: Typically Brown is VCC, Blue is GND, and Black is Signal. Please refer to the included datasheet for your specific batch.
