German hedland sensors hedland models hedland prices

hedland sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and are widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Proximity sensors can be classified into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, etc., based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which have an infrared emitting tube and an infrared receiving
