TCST1103 Sensor

The TCST1103 Sensor is a transmissive optical sensor designed for detecting objects, movement and position using an infrared emitter and phototransistor detector. Its slotted construction allows an object, encoder disc or mechanical part to interrupt the infrared beam, producing a corresponding output signal. The compact through-hole design makes it suitable for automation, counting, position sensing and embedded electronics projects.
