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.
Features:
- Integrated infrared LED and phototransistor in one compact unit
- Reliable object detection using beam interruption
- Built-in daylight blocking filter for stable performance in bright environments
- Ideal for use in optical switches, encoders, and automation projects
- Lead-free and environmentally compliant (RoHS & WEEE)
- Easy to mount and integrate into DIY or industrial applications
- Supports non-contact sensing for longer component life
