PR Series

Round section

The linear motion potentiometers series PR have a 26 mm diameter round section housing and 5 mm diameter shaft. Their measuring strokes range from 25 to 150 mm, and their standard resistive value is 5 KOhm.

The conductive plastic resistive element grants the transducer a long life (100,000,000 motions), high independent linearity  and virtually infinite resolution.

The IP65 protection degree against environmental agents allow to employ the potentiometers series PR for severe applications, even outdoors, at extreme temperatures.

The potentiometer PR mounting method is extremely easy: it can be fixed by means of metal clamping brackets, or by the front screw thread. Several fittings are available: ball joint, self-aligning joint, feeler pin.
