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.
Precision Potentiometers
Description
These wire-wound potentiometers are constructed with:
- 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.
Series and models
Standard models
Two different sizes provide two levels of power rating: size 15 (3 watts), size 18 (6 watts).
The four classes differ in the accuracy level and the ability to withstand environmental conditions:
| “PRECISION” Class
linearity ± 0.1% to ± 0.05% | “HEAVY INDUSTRY” Class
linearity ± 0.5% to ± 0.1% | “LIGHT INDUSTRY” Class
linearity ± 0.5% | “ECONOMY” Class
linearity ± 1% | ||
