Photointerrupter

A Photointerrupter is a device, containing light emitting elements and light receiving elements, that works by detecting light blockage, when a target object comes between both elements, acting as an optical switch.
Transmissive type: A signal is generated by simply interrupting the light beam by an obstacle.
Refrlective type: A light must be reflected by some sort of mirror.

Phototransistor Output / Reflective

Phototransistor Output, Reflective Photointerrupter:
It is a compact device with emitter and detector detector, facing the same direction in a molding molding, that provides non-contact sensing.

OPIC Output, Transmissive Photointerrupter:
It is a device with opposing emitter and detector in a case, providing non-contact sensing. Design: through-hole. Also available with 3-pin connector to allow remote-mount or off-board designs.
