The 3549S-2AC-103/103B is a 10-turn precision potentiometer featuring a wirewound element with dual gang configuration and 10 kO resistance per section. It offers independent linearity of ±0.2% (standard) or ±0.1% (maximum practical), with a total resistance tolerance of ±3% and an effective electrical angle of 3600° ±10°/-0°. The potentiometer is equipped with a nickel-plated brass shaft (1/4" diameter) and brass bushing, designed for bushing mount installation with optional anti-rotation lug capability. This precision instrument is RoHS compliant, features high rotational life, and is specifically designed for HMI (Human Machine Interface) and MMI (Man-Machine Interface) applications where accurate position feedback and control are essential.
