Capacitive Proximity Switch is changing the automation industry

The capacitive proximity switch is made by using the principle of changing the electrical capacity of the object under test by approaching it. It is a new type of non-contact sensing element, can be used for beverage, food, medicine, light industry, household appliances, chemical industry, mechanical operation in the stroke control and limit protection, automatic production line level detection, food and beverage packaging, sub-inspection, liquid level control, material counting, measuring length, measuring speed, etc.

In addition, it can also be used to develop a wide range of secondary instrumentation, burglar alarms, water tower level control products, and other household appliances. The existing inductive switch does not work for the detection of non-metallic objects, the photoelectric switch is subject to the detection of object transparency, color, reflective state, and the lens surface of the dust, gas, oil, and other factors, easy to cause misuse. Thus, capacitive proximity switches were developed for metal objects, non-metallic objects, solids, liquids, powders, granules, and other materials.
