Rotary potentiometer PR-18

manualprecisionwire-wound

Our potentiometers are wire wound potentiometers with high accuracy (linearity up to ± 0,05 %), high reliability and a long rotational life. They are used in a wide range of industrial applications and in railway applications. Each potentiometer is supplied at the required ohmic value in the range of feasible values. Multiple-units potentiometers are achieved by combining several units. • high-accuracy, low-temperature coefficient windings • a modular housing of light alloy supporting a stainless steel shaft with 2 precision roller bearings (except for the “Economy” class) • critical parts (slider, slip ring) made in precious metal alloys • a specific wiper technology with a double triangular arm, and redundant internal connections on some models for maximum reliability • numerous options: special variation laws, electrical and/or mechanical travel, intermediary taps, terminal wires, shaft design, housing, etc.
