Considerations & Choose

In the general industrial place of production, they are usually selected eddy inductive proximity switch and
capacitive proximity switch. Because these two proximity switches have low requirements for the environment.
A measured object is a conducting object, or an object that can be fixed to a piece of metal. Because of high
response frequency, good anti-interference performance, wide application range and low price, they are usually
choose eddy inductive proximity switch.
If the object is nonmetal (or metal), liquid level, powder height, plastic, tobacco. Select and use capacitive
proximity switch . This switch has a low response frequency but a good stability. The effect of environmental
factors should be taken into account when installing.
If the measured material is a magnetic material, differentiating the magnetic materials from two objects, the Holzer
proximity switch can be selected.
In the environment with better environmental conditions and no dust pollution, photoelectric proximity switch
can be used. The optoelectronic proximity switch has little effect on the object being measured. For example, high
demand for facsimile machines and tobacco machines.
In the anti-theft system, the automatic door usually uses the pyroelectric proximity switch, the ultrasonic proximity
switch, and the microwave close to the switch. In order to improve the reliability of recognition, several proximity
switches are used together.
It is necessary to pay attention to the requirements of working voltage, load current,

response frequency and measuring distance.
