Introduction to photoelectric beam sensor


In general, the photoelectric beam sensor is composed of three parts, which are divided into: transmitter, receiver and detection circuit. The transmitter is aimed at the target to emit a light beam.

In general, the photoelectric beam sensor is composed of three parts, which are divided into: transmitter, receiver and detection circuit. The transmitter is aimed at the target to emit a light beam, and the emitted light beam generally comes from a semiconductor light source, a light emitting diode (LED), a laser diode, and an infrared emitting diode. The beam is emitted uninterrupted, or the pulse width is changed. The photoelectric beam sensor manufacturer tells you that the receiver is composed of photodiodes, phototransistors, and photocells. In front of the receiver, optical components such as lens and aperture are installed. Behind it is the detection circuit, which can filter out the effective signal and apply the signal.

The photoelectric beam sensor manufacturer tells you that the photoelectric detection method has the advantages of high accuracy, fast response, non-contact, etc., and there are many measurable parameters, the structure of the sensor is simple, and the form is flexible and diverse. Therefore, the photoelectric sensor is widely used in detection and control.
The photoelectric beam sensor is a key element for photoelectric conversion in various photoelectric detection systems. It is a device that converts optical signals (visible and ultraviolet laser light) into electrical signals.
The photoelectric beam sensor is a sensor that uses a photoelectric device as a conversion element. It can be used to detect non-electrical physical quantities that directly cause changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; it can also be used to detect other non-electrical quantities that can be converted into light quantity 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, etc. The photoelectric beam sensor has the characteristics of non-contact, fast response, reliable performance, etc., so it is widely used in industrial automation devices and robots.
