How to choose between inductive and capacitive proximity switches?

When the object to be measured is a conductive object or an object that can be fixed on a metal object, an inductive proximity switch is usually used because it has a high response frequency, good anti-interference performance, wide application range and Low price. .

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

Use of proximity switch sensors:

These proximity switch sensors are widely used in aerospace, aerospace technology and industrial production; in daily life, such as hotels, restaurants, garages, automatic Automatic doors with hot air blowers; In terms of safety and security, heavy-duty areas such as data files, accounting, finance, museums and finance are usually equipped with anti-theft devices with various proximity switches. In measurement technology, such as length and position measurement; in control technology, such as displacement, velocity, acceleration measurement and control, there are also a large number of uses. The way to use it is usually a proximity switch.
