TCRT5000 Pinout Equivalent

1：Overview of the TCRT5000:

TCRT5000 is a commonly used infrared reflective photoelectric sensor. It consists of an infrared emitting tube and an infrared receiving tube. By emitting infrared light and detecting the intensity of reflected light, it can judge the existence or distance of an object in front. It has a wide operating voltage range, generally from 3.3V to 5V. It has characteristics such as small size, high sensitivity, fast response speed, and low cost. It is often used in related application scenarios of automated control and intelligent devices such as robot tracking, object detection, and position detection.

3：Alternative model recommendation

QRE1113：Reflective photoelectric switch, similar to the TCRT5000, combines an infrared emitter and receiver to detect the presence of objects or changes in reflected light intensity, thereby determining the position or distance of the object.

ITR8102：This is a groove transmission photoelectric switch, which is formed by pairing an infrared emitting tube with an infrared receiving tube. It has the characteristics of long service life, high reliability, and fast response speed. It is suitable for scenarios such as position movement detectors, tape detectors, tape feeding control, and contactless switches. In some occasions where the position accuracy requirements for the detected object are relatively high and the object’s movement trajectory is relatively fixed, it can be used as a substitute for TCRT5000.

GP2Y0A21YK0F：The Sharp infrared distance sensor measures distances from 10 to 80 cm and outputs an analog signal. Compared to the TCRT5000, it provides more precise measurements of the distance between objects and the sensor, making it suitable for applications that require high accuracy in distance measurement.

E18 – D80NK：Infrared diffuse reflection proximity photoelectric switch, type NPN three-wire system, typically operates at 5V or 24V.
