Close-to-switch devices are widely used in our industrial production. Nowadays, many intelligent production equipment can not be separated from close-to-switch. The birth of weighing small-to-close switches will improve our operational efficiency to a certain extent. Do we have a certain understanding of the precautions for small-to-close switches?

In general industrial production places, eddy current remote proximity switch and capacitive proximity switch are commonly used. Because these two adjacent switches have lower environmental requirements.

When the object to be measured is a conductive object or an object that can be fixed on a metal object, eddy current proximity switch is generally used, because it has high echo frequency, good anti-environmental interference performance and wide application scale. The price is lower.

If the object is right or wrong metal (or metal), liquid level, powder height, plastics, tobacco, etc. Capacitive proximity switches should be used. The switch has low response frequency but good stability. Environmental factors should be considered during installation.

If the object to be tested is a magnetic conductive material or the magnet is embedded in the object to be tested in order to distinguish it from the moving object, the Hall proximity switch with the lowest price should be used.
