The 3549S-2AA-104/104A is a dual-gang 10-turn precision potentiometer featuring wirewound elements designed for high-accuracy control in HMI and MMI applications. It offers a standard resistance range of 100 kO with ±3% total resistance tolerance and independent linearity of ±0.2%, with an effective electrical angle of 3600° ±10°/-0°. The potentiometer is available with bushing mount configuration, featuring nickel-plated brass or stainless steel shafts with brass or bronze bushings, and includes optional anti-rotation lugs and dual ball bearing options. Its high rotational life, RoHS compliance, and suitability for side-load conditions make it ideal for precision instrumentation, servo control systems, and industrial control panels requiring reliable multi-turn adjustment.
