The 3549S-1AA-203B is a 10-turn wirewound precision potentiometer designed for accurate rotational position sensing. It features a 20 kOhm resistance element with a total resistance tolerance of ±3% and an enhanced independent linearity of ±0.1%. This single-gang component is rated for 2 watts of power at +70°C and has a high rotational life of 2,000,000 shaft revolutions. Operating over a dynamic temperature range of -40°C to +125°C, it is well-suited for demanding human-machine interface (HMI) and machine-to-machine (MMI) applications requiring reliable and precise control.
