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.
