The 3548S-1AA-102A is a 5-turn precision potentiometer featuring a wirewound element with a nominal resistance of 1 kO and independent linearity of ±0.25%. This single-gang, bushing-mount potentiometer is designed for high-accuracy applications requiring stable performance over extended rotational cycles, with an effective electrical angle of 1800° ±10°/-0°. The device incorporates a nickel-plated brass shaft and brass bushing (standard configuration), along with optional anti-rotation pin capability for secure mounting. The wirewound construction provides excellent resolution of 0.043% and is RoHS compliant, making it suitable for HMI and MMI applications where precision and reliability are critical requirements.
