The 3549H-1AC-502B is a 10-turn precision potentiometer featuring a Hybritron element with a 5K ohm resistance value. It offers independent linearity of ±0.2% (with optional ±0.1% maximum practical linearity) and an effective electrical angle of 3600° ±10°, -0°, providing precise analog control over multiple rotations. The potentiometer features high rotational life, low starting and running torque of 0.5 N-cm maximum, and is RoHS compliant. It is designed for human-machine interface (HMI) and man-machine interface (MMI) applications, with optional configurations including dual gang, servo mount, and dual ball bearing options. The device is suitable for use under some side load conditions and offers excellent mechanical stability with backlash of 1.0° maximum and shaft runout of 0.08 mm TIR.
