Photoelectric Tripwire Sensor 20m PR18S-TM20DPO - Emitter Receiver Pair
The Lanbao PR18S-TM20DPO uses the most reliable and accurate style of photoelectric sensing which is the through beam sensor. The sensor comes with a pair of an emitter and a receiver. The emitter provides a constant invisible IR (infrared) beam of light to the receiver and detection occurs when an object passing between the two breaks the beam. The photodetection range of the PR18S-TM20DPO is up to 20 meters.
A very familiar application of a through-beam photoelectric sensor can be found is right in your home. Quite often, a garage door opener has a through-beam photoelectric sensor mounted near the floor, across the width of the door. This sensor is making sure nothing is in the path of the door when it is closing.

This sensor requires a 12V power supply and outputs a 0-5V signal depending on whether the sensor is triggered. For a simple way to provide 12 volts, you can use our 12V sensor adapter. It uses the 5V supply from your InterfaceKit or Hub and steps it up to 12V while simultaneously passing the 0-5V signal from the sensor into the Phidget cable.
