Photoelectric sensors are sensors that use various properties of light to detect the presence or absence of an object and change in surface state. They are mainly composed of a light-emitting projection unit and a light-receiving unit that receive light. If the projected light is blocked or reflected depending on the detection object, the amount of light reaching the light-receiving part will change. The light receiving unit detects this change and converts it into an electrical signal for output.   Optimized circuit design, strong anti-interference ability High reliability and high accuracy Metal case for easy installation and protection Adjustable sensitivity Suitable for multiple applications Compact design with built-in amplifier Far distance detection
