Static ring and tube sensors operate like inductive sensors. They generate an output signal when there is metal in the detection zone. For example, the sensors can be used for jam control in feed processes.
Dynamic sensors are used when particularly small parts are to be detected. During a damping operation a short pulse is generated at the output of the sensor, adjustable from 0.1 to 150 ms. The functionality will remain stable for a long time, even in the case of metal contamination in the tube.
