Counting frequency is the frequency at which a sensor can detect an object within a specified time period. Sensors are used in conjunction with counters, which can count object passes or machine revolutions, for example. Counting frequency is an important consideration in such applications.

Counting frequency is one of the technical specifications of a sensor and represents the number of detections the sensor can make within a certain time period. For example, if a sensor has a counting frequency of 100 Hz, it means that the sensor can detect an object 100 times within one second.

The counting frequency of a sensor can vary depending on the intended use of the sensor and the requirements of the application. Some industrial applications require high-precision and high-speed counting frequencies, while others may only require lower frequencies.

Therefore, when selecting a sensor, it is important to choose a counting frequency that meets the requirements of the application.
