Vishay / Spectrol Model 157 Precision Industrial Potentiometers
Vishay/Spectrol Model 157 Precision Industrial Potentiometers are 7/8" (22.2mm) components constructed with conductive plastic available in bushing and servo mount variants. These potentiometers offer a 1kΩ to 100kΩ resistance range with ±10% or ±20% tolerance options, a 360° continuous rotation, and a 340° (±4°) electrical angle within a wide temperature range. A rugged one-piece metal housing helps to ensure long rotational life.
