German DAHLEM sensor DAHLEM model DAHLEM price

DAHLEM 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 have achieved widespread adoption. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Distance sensors can be classified into optical distance sensors, infrared distance sensors, ultrasonic distance sensors, and others based on their working principles. Most distance sensors used in mobile phones are infrared distance sensors, which feature an infrared emitting tube and an infrared receiving
