The magnetic core inside the proximity switch passes through the metal to change the internal oscillation circuit and output a signal. Suitable for detecting metal objects with relatively close distances.

For different material samples and different detection distances, different types of proximity sensors should be used to make them have a high performance-price ratio in the system. The following

The capacitance value of the capacitive sensor is generally independent of the electrode material, which is advantageous for selecting a material with a low temperature coefficient, and the heat generation is

The switch that is close to life can reach more than one million times. The reason for this long life is that the function of the switch is the elasticity from the vertical direction of the elastic film. Although there

The light sensor is composed of two components, a light projector and a light receiver. The light is focused by the lens by the light projector, transmitted to the lens of the light receiver, and then to the receiving
