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 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

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

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.

According to its basic sensing function, it can be divided into thermal sensor, photosensitive element, gas sensor, force sensor, magnetosensitive sensor, humidity sensor, sound sensor, radiation sensor,

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

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.

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.
