PR20 Geared Potentiometer

Rotation of a hollow shaft is transferred through a gear set to a precision rotating potentiometer, allowing for a simple yet effective absolute encoder solution.

The potentiometers are available with 1, 3, 5, or 10 revolutions with a transmission gear ratio between the drive shaft and the potentiometer. The transmission is provided with a clutch for the protection of the potentiometer.

Appropriate specification requires total number of revolutions in the range of motion. The number of revolutions is calculated as the transmission gear ratio (multiplier or reduction) times the potentiometers turns.

The PR20CAN transducer provides CANopen DS301 serial output.

The version PR20HALL is made of a single turn potentiometer with Hall effect (non-contact).

Ideal for machines tool, automatic wood/marble/glassworking machinery, etc., with an accuracy not higher than ±0,1 mm.

Shock-proof, self-extinguishing case, solvent-,gasoline-,oil-, grease-proof.

3D DRAWING AVAILABLE UPON REQUEST.
