1. After the modulation pulse generated by the vibration circuit passes through the reflection circuit, the digital integration photoelectric switch or RC integration method is used to eliminate the disturbance, and finally the driver is triggered by a delay (or no delay) to output the photoelectric switch control signal.
2. Use optical elements to change the beam in the middle of the propagation medium; Use a beam of light to reflect objects; Causes the beam to return instantaneously after a long distance. The photoelectric switch is composed of three parts: transmitter, receiver and detection circuit. The emitter is aligned with the emitted beam, which is typically sourced from light-emitting diodes (LEDs) and laser diodes.
3. The beam is emitted uninterruptedly, or the pulse width is changed. The radiation intensity of the pulse-modulated beam is selected many times during the emission and does not indirectly move towards the direction. The receiver consists of either a photodiode or a phototriode. In front of the receiver, optical elements such as lenses and aperture are installed. Behind it is the detection circuit, which filters out the desired signal and applies it.
4. After the modulation pulse generated by the vibration circuit passes through the reflection circuit, the light pulse is radiated by the light-emitting tube GL. When the measured object enters the range of effect of the light receiver, the reflected light pulse enters the phototransistor.
5. The photoelectric switch is demodulated into an electrical pulse signal in the receiving circuit, and then amplified by the amplifier and synchronously gated and shaped, and then the disturbance is eliminated by the digital integration or RC integration method, and finally the driver is triggered by a delay (or no delay) to output the photoelectric switch control signal.
6. The photoelectric switch generally has good return characteristics, so even if the detected object shakes in a small range, it will not affect the output of the driver, so that it can be kept in a stable operation area. Together, the self-diagnostic system can also display the light reception status and stabilize the work area to monitor the operation of the photoelectric switch at any time.

Strengths of Autonex photoelectric sensors
1. Long detection interval. By retaining an inspection interval of more than 10 m in the through-beam model, other inspection methods can be accomplished.
2. Less detection of objects. Because the detection of shading and reflection caused by the object is the detection principle, it is not like the proximity sensor to limit the detection of the object to the metal ...

The difference between laser sensors and photoelectric sensors – Autonicx
First, the difference in working principle
Photoelectric sensors are controlled by converting changes in light intensity into changes in electrical signals. The laser sensor first emits a laser pulse by aligning it with a laser emitting diode. After being reflected, the laser light is scattered in all directions. Partially scattered light returns to ...
