The TCRT5000L Infrared Reflective Optical Sensor is a leaded component combining an infrared emitter and a phototransistor in a single package, detecting nearby objects by sensing the IR light they reflect back. It’s widely used in line-following robots, object-counting systems and proximity-detection projects.
Key features:
- Detection Type: Reflective infrared sensing using an integrated emitter and phototransistor pair.
- Daylight Blocking Filter: Built-in filter reduces interference from ambient visible light.
- Detection Range: Effective sensing distance of roughly 0.2mm to 15mm.
- Compact Leaded Package: Snap-in mounting clips simplify placement on a PCB.
- Fast Response: Microsecond-range switching time suits line-tracking and speed-sensitive applications.
- Wide Compatibility: Pairs easily with comparator modules such as the LM393 for digital output.
It’s a low-cost building block for line-following robots, tachometers and simple object-presence detection.
