Opto Interrupter TCST2103

Opto Interrupter TCST2103

The Opto Interrupter TCST2103 consists of an infrared LED emitter and a phototransistor detector. It works by letting the IR LED constantly emit light to the phototransistor to allow current flow. And when the light beam is blocked, the current flow stops. This makes the device suitable as an optical switch. Moreover, this particular opto interrupter is coated with a lead filter to avoid ambient light noise. It works great even in broad daylight.
