The 3549S-2AA-502/502A is a dual-gang 10-turn precision potentiometer featuring wirewound elements designed for high-accuracy applications. It offers a standard resistance of 5 kO (502 code) with ±3% total resistance tolerance, independent linearity of ±0.2%, and an effective electrical angle of 3600° ±10°/-0°. The potentiometer is constructed with nickel-plated brass shaft and brass bushing (standard configuration), providing high rotational life and suitability for use under some side load conditions. This device is ideal for human-machine interface (HMI) and man-machine interface (MMI) applications, offering RoHS compliance and optional features such as anti-rotation lugs and servo mount configurations.
