Wirewound technology with oil filling — stable operation under challenging conditions
The hermetically sealed, oil-filled design of this wire-wound linear potentiometer provides reliable protection against environmental influences and ensures a stable output signal throughout its entire service life. Thanks to the wire-wound technology, the sensor can handle higher electrical loads (up to 3 W, depending on the measurement length). For precise measurement tasks, operation as a voltage divider is recommended, as this keeps the wiper current low and the signal reproducible.
