Advantage
Short response time
The light itself is high-speed, and the circuit of the sensor is composed of electronic parts, so no mechanical working time is included, and the response time is very short.
High-resolution
High-resolution design techniques can be used to concentrate the projected beam on a small spot, or to form a special light-receiving optical system to achieve high resolution. It can also detect small objects and high-precision position detection.
Less restrictions on detecting objects
As the detection principle is based on the shading and reflection caused by the detection object, it can detect almost all objects such as glass, plastic, wood, liquid, etc., unlike the proximity sensor, which limits the detection object to metal.
The diffuse reflection type photoelectric sensor is integrated with the transmitter and receiver. Under normal circumstances, the receiver cannot receive the light emitted by the transmitter. When the detected object passes through, it obstructs the light and reflects part of the light back, and the receiver receives Optical signal, output a switch control signal.
Features of diffuse reflection photoelectric sensor
>No need to align the light path during installation
>Save installation space
>Easy installation and wiring
>Large detection area
The light-emitting device and the light-receiving device are installed in the same device, a reflector is installed in front of it, and the photoelectric control function is completed by the principle of reflection, which is called a mirror reflection photoelectric switch. Under normal conditions, the light emitted by the light emitter is reflected by the reflector and received by the light receiver; once the light path is blocked by the detection object and the light receiver cannot receive light, the photoelectric switch will act and output a switch control signal
Features of reflective photoelectric sensor
>Easy to align the light path during installation and use
>Compared with reflective photoelectric sensor, save installation and use space
>Easy installation and wiring
>Not affected by detected objects, colors and materials
