The P+F Pepperl+Fuchs photoelectric sensor produces photoelectric effect after being irradiated by visible light, and converts the light signal into an electrical signal for output. The Pepperl+Fuchs photoelectric sensor is an important sensitive device with a wide range of applications. The photoelectric measurement does not directly contact with the measured object, and the quality of the beam is approximately zero. There is no friction and almost no pressure on the measured object during the measurement.

Pepperl+Fuchs photoelectric sensor

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. Therefore, in many applications, photoelectric sensors have obvious advantages over other sensors. The disadvantage is that in some applications, optical devices and electronic devices are more expensive and require higher environmental conditions for measurement. It is a physical phenomenon in which light irradiates certain substances to change the conductive properties of the substance. It can be divided into three types: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Pepperl+Fuchs photoelectric sensor through-beam photoelectric switch is composed of transmitter and receiver. The two are separated in structure. When the beam is interrupted, a switch signal change will occur. The typical way is on the same axis. The photoelectric switches can be separated from each other up to 50 meters. Pepperl+Fuchs proximity switch is widely used in automatic counting, safety protection, automatic alarm and limit control, etc. It is one of the most commonly used sensors in sensors.
