To carry out a specific measurement work, we must first consider the principle of the sensor, which needs to be analyzed after analyzing various factors. Because even if it is measuring the same physical

A proximity sensor is a device that is capable of detecting the distance between two objects and controlling or driving an actuator according to preset limits. Therefore, it has a wide range of uses in many fields.

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 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

Mounting a light emitter and a receiver face to face on either side of a slot is a trough optoelectronic. The illuminator emits infrared or visible light, and the light receiver receives light in an unobstructed condition.

The linear range of the sensor is the range in which the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the sensor, the larger its

Most of the thermal resistances are made of pure metal materials. Currently, platinum and copper are the most widely used. In addition, thermal resistances such as nickel, manganese and tantalum have been used.

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.

The frequency response characteristics of the sensor determine the range of frequencies being measured and must remain undistorted within the permissible frequency range. In fact, the response of the
