P+F Pepperl+Fuchs sensor uses core to create a miracle in the field of sensing

The photoelectric detection method has the advantages of high accuracy, fast response, non-contact, etc., and many measurable parameters. The P+F Pepperl+Fuchs photoelectric sensor has a simple structure and 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.

Because photoelectric sensors are also classified, let’s share with slot photoelectric sensors first: Slot photoelectric sensor is a slot photoelectric sensor which is a light emitter and a receiver mounted face to face on both sides of a slot. The illuminator can emit infrared light or visible light, and the light receiver can receive light without obstruction. But when the detected object passes through the slot, the light is blocked, the photoelectric switch will act, and output a switch control signal to cut off or turn on the load current, thereby completing a control action. The detection distance of the 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 through-beam photoelectric switch. The detection distance of the through-beam photoelectric switch can reach several meters or even tens of meters. 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 detected object, and the light path is blocked when the detected object passes, and the light receiver acts to output a switch control signal. Under normal circumstances, P+F Pepperl+Fuchs photoelectric sensors can be divided into through-beam type, groove type, optical fiber, color code, color and other types.
