Bourns 3549S1AA501A 10-Turn Precision Potentiometer
The Bourns 3549S-1AA-501A is a high-precision, 10-turn potentiometer designed for demanding applications requiring accurate and reliable position feedback. It utilizes wirewound and Hybritron elements to achieve exceptional performance characteristics, including high rotational life and low output smoothness. This potentiometer is well-suited for human-machine interface (HMI) and machine-machine interface (MMI) systems, as well as servo applications. Available options include enhanced linearity, A/R lugs, and dual ball bearings to meet specific design requirements. Its robust construction and environmental resistance ensure reliable operation in challenging conditions.
