P+F Pepperl+Fuchs sensor okplazas.com has good reputation and after-sales guarantee

P+F Pepperl+Fuchs photoelectric sensor, also called photoelectric switch. It is a sensor that uses a photoelectric element as the detection element. It first converts the measured change into a change in an optical signal, and then further converts the optical signal into an electrical signal with the help of photoelectric elements. The photoelectric sensor is generally composed of three parts: a light source, an optical path, and a photoelectric element.

P+F Pepperl+Fuchs photoelectric sensor is a sensor with photoelectric device as the conversion element. It can be used to detect non-electric quantities that directly cause changes in light, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; it can also be used to detect other non-electric quantities that can be converted into light changes, such as part diameter, surface roughness, strain , Displacement, vibration, speed, acceleration, as well as the recognition of the shape and working state of the object. Photoelectric sensors have the characteristics of non-contact, fast response, reliable performance, etc., so they are widely used in industrial automation devices and robots. The important function of the photoelectric switch The important function of the photoelectric switch is to be able to handle the change of light intensity: use the light beam to reflect the object; make the light beam return instantaneously after a long distance. Special advantages: fast sensing speed, long service life, smart and easy to install and use. Photoelectric switch type proximity switches are widely used in automatic counting, safety protection, automatic alarm and limit control. In general, photoelectric switches can be divided into opposing type; diffuse reflection type; specular reflection type; slot type photoelectric switch; optical fiber type photoelectric switch. okplazas.com stocks Pepperl+Fuchs photoelectric switches and also distributes encoders, safety barriers, power supplies, solenoid valves, surge protectors and other related products.
