  • Inductive proximity switch consists of three parts: oscillator, switching circuit and amplification output circuit. The oscillator generates an alternating magnetic field. When the metal target approaches this magnetic field and reaches the induction distance, eddy current will be generated in the metal target, resulting in oscillation attenuation and even vibration stop. The changes of oscillator oscillation and stop vibration are processed by the later stage amplification circuit and converted into switching signals to trigger the driving control device, so as to achieve the purpose of non-contact detection.

  • Proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When the sensing surface of the object proximity switch reaches the action distance, the switch can act without mechanical contact and applying any pressure, so as to drive DC appliances or provide control instructions to computer (PLC) devices.

  • Long detection distance: compared with inductive proximity switch, it can obtain a long detection distance. For example, the detection distance of opposite type switch can reach tens of meters, and the reflection has ranged from a few centimeters to a few meters. Because it is non-contact detection, it will not damage or be affected by the measured object.

  • Identification of photoelectric switch wiring: BK (black): generally, it is an output line, and the output is normally open. BN (brown): it is generally a power line, connected to the positive pole of the power supply.

  • Diffuse reflection type is that when the switch emits light beam, the target generates diffuse reflection. The transmitter and receiver form a single standard component. When enough combined light returns to the receiver, the switch state changes. The effective action distance is determined by the reflection ability of the target and by the surface properties and color of the target; With less assembly cost, when the switch is composed of a single element, it can usually achieve rough positioning;
