The detection distance of the P+F Pepperl+Fuchs sensor slot switch is generally only a few centimeters due to the limitation of the overall structure. For the through-beam photoelectric sensor, if the light emitter and the light receiver are separated, the detection distance can be increased. A light emitter and a light receiver form a through-beam separated photoelectric switch, referred to as a through-beam photoelectric switch. The detection distance of the through-beam photoelectric switch can reach several meters or even tens of meters.

The photoelectric detection method has the advantages of high accuracy, fast response, non-contact, etc., and has many measurable parameters. The P+F Pepperl+Fuchs sensor photoelectric sensor has a simple structure, flexible and diverse forms, so the photoelectric sensor is widely used in detection and control. It is a key component of photoelectric conversion in various photoelectric detection systems. It is a device that converts optical signals into electrical signals. The photoelectric sensor realizes control by converting changes in light intensity into changes in electrical signals. In general, the photoelectric sensor is composed of three parts, which are divided into: transmitter, receiver and detection circuit. . When the through-beam photoelectric switch is used, the light emitter and the light receiver are respectively installed on both sides of the passing path of the detection object, and the light path is blocked when the detection object passes, and the light receiver acts to output a switch control signal. Under normal circumstances, photoelectric sensors can be divided into through-beam type, groove type, optical fiber, color code, color and other types.
