Eddy Current Sensors

These non-contact position sensors and position measurement systems rely on eddy currents. To measure a position, they transform the distance to a magnetizable or non-magnetizable metal surface into a proportional voltage output. Although the contactless position sensors are available for measurement ranges from 0.5 mm to 60 mm, most applications are between 1 and 6 mm. Since the area targeted by the eddy current sensor needs to be between 1.5 and 2.5 times the size of the measurement range in each direction, the target for a measurement of 60 mm would have to be at least 100 mm wide.

The ThreadChecker is a specialized version of these non-contacting distance sensors for detecting and identifying inside threads. This reduces losses in automated drilling, tapping, and driving processes.
