The P+F Pepperl+Fuchs photoelectric sensor uses optical elements to change the light beam in the middle of the propagation medium; uses the light beam to reflect the object; makes the light beam return instantaneously after a long distance. The photoelectric switch is composed of three parts: transmitter, receiver and detection circuit. Use optical elements to change the light beam in the middle of the propagation medium; use the light beam to reflect the object so that the light beam is emitted through.

P+F Pepperl+Fuchs photoelectric sensors can be divided into three types according to the structure: the amplifier separated type, the amplifier built-in type and the power supply built-in type. It integrates the amplifier and the sensor, is made with a dedicated integrated circuit and surface mounting technology, and works with a DC power supply. Its response speed situation (there are two kinds of 0.1ms and 1ms), can detect small and high-speed moving objects. The photoelectric sensor has both voltage and current output modes, which can prevent mutual interference and is very convenient in system installation. Today we talk about diffuse reflection photoelectric switches. The typical value of the diffuse reflection distance is up to 3 meters. Features: The effective range is determined by the reflectivity of the target, and is determined by the nature and color of the target surface; less assembly expenses, when the switch is composed of a single element, it is usually possible to achieve coarse positioning; the background suppression function is used to adjust the measurement distance ; Sensitive to dust on the target and sensitive to the changed reflection performance of the target. According to the detection, it can be classified as: According to the detection method, it can be divided into diffuse, opposite, mirror reflection, slot photoelectric switch and optical fiber photoelectric switch.
