TCRT5000 Tracking Line Follower Sensor

TCRT5000 Reflective Optical Sensor – Precision Line Following and Object Detection​

The digital output allows connection of the sensor to any board equipped with a microcontroller, e.g.Arduino, STM32 Discovery or minicomputer Raspberry Pi.

Features:

• Integrated Design: Combines an infrared emitter and a phototransistor in a single package, minimizing external component requirements.​
• Visible Light Blocking: Designed with a housing that blocks visible light to reduce interference from ambient lighting conditions.​
• Adjustable Detection Range: Effective sensing range from 0.2 mm to 15 mm, suitable for various proximity detection tasks.​
• Compact Form Factor: Package dimensions of 10.2 mm x 5.8 mm x 7 mm, facilitating easy integration into space-constrained designs.​
• Mounting Flexibility: Available in standard and long-lead versions (TCRT5000L), offering versatility for different mounting requirements.​
