Hunter's comment

It is a simple plastic sensor with a cable to T-slot photo interpreter. Which has two elements. There is an IR Led and an IR Photo Transistor. These sensors are easy when you want to find out whether some sensor has passed through the slot. In this sensor, a down-site will be mentioned that there are power requirements inside the circuit, you can use this sensor with 3 devices.
