Opto Interrupter TCST2103

The Opto Interrupter TCST2103 is a compact sensor module that includes an infrared LED emitter and a phototransistor detector positioned face-to-face in a slotted housing. It functions by allowing infrared light from the emitter to continuously reach the detector, enabling current to flow. When an object passes through the slot and interrupts the light beam, the current flow is cut off—making it an ideal choice for detecting motion, position, or the presence of objects. This simple yet effective switching mechanism makes it popular for use in optical encoders, motor feedback systems, and automation projects.

What sets the TCST2103 apart is its built-in daylight filter, which helps block out ambient light interference. This means the sensor remains reliable and accurate even in bright environments, such as near windows or outdoors. Whether you're building a line-following robot, a rotating wheel sensor, or any project that requires non-contact object detection, this opto interrupter is a dependable and easy-to-integrate component.
