Infrared Emitter: The sensor includes an infrared emitting diode (IRED) that emits infrared light in the near-infrared spectrum.
Phototransistor: It also features a phototransistor that detects the infrared light reflected from surfaces or objects.
Analog Output: The sensor provides an analog output signal based on the intensity of the reflected or interrupted light, allowing for continuous monitoring or detection.
Sensitivity Adjustment: Some variants of the H21A1 may feature sensitivity adjustment options, allowing users to optimize detection parameters.
Low Power Consumption: The sensor typically operates at low power, making it suitable for battery-powered devices and applications.
Reflective Opto-Sensing: It can be employed in reflective opto-sensing applications, such as detecting the presence of reflective tapes or markers.
Encoder Systems: Used in encoder systems for position and motion detection by sensing interruptions or changes in the infrared light path.
