Bourns 3549S2AA102102A 10-Turn Precision Potentiometer
The Bourns 3549S-2AA-102/102A is a high-precision, 10-turn potentiometer designed for demanding applications requiring accurate and reliable position sensing. It utilizes wirewound and Hybritron elements to achieve exceptional performance characteristics, including high rotational life and low noise. This potentiometer is well-suited for use in human-machine interface (HMI) and machine-machine interface (MMI) systems, as well as servo applications. Optional features such as improved linearity, A/R lugs, and dual ball bearings further enhance its versatility and performance. Its robust construction and environmental resistance make it suitable for a wide range of industrial environments.
