Rotary potentiometer ERP50 Series

Image ERP50

The ERP50 Series works with a potentiometric principle. It can be used to measure angular displacements. The sensor can handle over range without damage since there is not mechanical rotation limitation.

Since they are analogue outputs, they operate as a absolute sensor, ie they do not lose their position during power / power cuts and continue to measure from where they left off.

The linearized conductive plastic (Carbon + Plastic alloy) resistive alloy and special contacts are not affected by abrasion and operate for long periods of time.
