Photo Interrupter

Product Ordered On Demand Only

A Photo interrupter is a transmission-type photo sensor, which typically consists of a light emitting elements and light receiving elements aligned facing each other in a single package, that works by detecting light blockage when a target object comes between both elements, acting as an optical switch.

Application

1.You can use the photo interrupter for controlling the position of a moving part (check if the part is in the desired position or not) or you can count pulses from a rotating index disc to measure the rpm of your motor (aka rotary encoder) or whatever you want.

2. Sensing & Instrumentation, Computers & Computer Peripherals.
