Good for light automation

Works well for counting items on a conveyor. Note that shiny surfaces can affect detection range slightly.

Solid performance

Does exactly what it says. The LEDs are bright enough to see status clearly. Cable could be longer but manageable.

5 FAQ

Q: Is this compatible with 5V Arduino boards?

A: Yes, the module operates between 3V and 30V, so 5V logic works perfectly.

Q: Can it detect black objects reliably?

A: Dark colors absorb infrared light, which may reduce the effective detection distance. We recommend testing with your specific target.

Q: What is the wiring configuration?

A: Brown is VCC, Blue is GND, and Black is the Signal Output. Please refer to the datasheet for diagrams.

Q: Can I use this outdoors?

A: Strong sunlight contains infrared radiation which may interfere with performance. It is best suited for indoor use.

Q: Is the output Normally Open or Normally Closed?

A: The output is NPN Open Collector. It pulls low when an object is detected.
