Datalogic SM-PR-2-A00-NN in brief
- What it is: a Datalogic SM series subminiature retro-reflective sensor
- Light: visible red LED for easy alignment
- Outputs: NPN, NO and NC
- Needs: a reflector such as the Datalogic RL 201
- Connection: fixed 2 m cable
Order the SM-PR-2-A00-NN
How a retro-reflective sensor works
A retro-reflective sensor sends light to a reflector and receives it back in the same housing. When an object breaks the beam, the output switches. Only one unit needs wiring, which makes installation simpler than a through-beam pair.
The SM-PR-2-A00-NN offers both NO and NC NPN outputs, so you can use either logic without changing the sensor. Visible red light makes aligning it to the reflector quick.

Installation and setup tips
Mount the sensor facing a reflector such as the Datalogic RL 201 and align the red spot on it. Wire brown and blue to 24 V DC and use the NO or NC NPN output as your logic needs. Check that the output changes cleanly when an object passes.
