About this product
A transmissive photo interrupter with an infrared LED facing a phototransistor across a 10 mm gap. An object passing through the gap blocks the beam and changes the output, so it behaves like an on/off switch. It is used for counting revolutions, tachometer speed sensing, tape-end detection and edge sensing in machines and printers.

How do I wire the output?
The phototransistor output needs a pull-up resistor to the logic supply, and the output line goes to a digital input. Power the IR LED side through a current-limiting resistor as specified in the datasheet.
Can I measure motor speed with it?
Yes. Mount a disc with slots or spokes on the shaft so it passes through the gap. Each slot produces a pulse, so counting pulses per second gives the rotation speed.
