Capacitive ifm sensors have many applications in everyday life. It is capable of viewing non-metallic materials as well as detecting objects in a non-contact manner.
Capacitive ifm sensors are resistant to interference. When an object is detected, capacitance changes as small as 0.02pF need to be accurately converted into usable switching signals. Since the basic capacitance required for circuits and structures, such as the input capacitance of components and conductor circuits, has increased many times, the requirements for circuits are relatively high when used, which greatly increases the difficulty of detecting the capacitance with maximum accuracy.
Inductive ifm sensors detect metals without contact and are used in a wide range of industrial applications. Compared to mechanical switches, inductive sensors offer prerequisites, high switching accuracy and switching frequency, as well as wear-free and contact-free working methods. They resist moisture and dust, and are resistant to shocks.
In contrast to inductive sensors, which can only detect metallic objects, capacitive ifm sensors can detect non-metallic materials and can detect any object in a contactless way. Typical areas of application are the paper, plastics, food, chemical, glass and wood industries.

Selection of sensor sensitivity and range – ifm
The sensitivity of the sensor is one of the most basic goals of the sensor. The sensitivity of the sensor directly affects the measurement of the oscillation signal. It is not difficult to understand that the sensitivity of the sensor should be determined according to the size of the oscillation (acceleration value) to be measured, but since piezoelectric acceleration is a measurement of the acceleration value of the oscillation, ...
