Description
The Kromschroder feedback potentiometer 74921144 is a spare part designed for use with IC 20 and IC 20..T actuators. It operates as a voltage divider with a resistance of 1000 ohm and a linear taper, providing position feedback for the actuator shaft. The device has a rotation angle of 90° (0° to 90°), an accuracy of ±5%, and a maximum power of 0.5 W. It can operate in ambient temperatures up to 85 °C and weighs 32 g.

Choosing and fitting
Parts of this type are selected by matching the total resistance and mechanical interface (shaft diameter, length, and mounting hole pattern) to the original part. The resistance curve (linear or logarithmic) must match the control board's input requirements. Before ordering, verify the rotation angle and ensure the actuator's cams are set within the specified angle limits to prevent damage.
Signs of failure
When items of this kind fail, the equipment may exhibit erratic modulation or fail to reach the programmed output. This can be caused by a worn potentiometer, leading to incorrect feedback signals. Check electrical continuity and linearity over the full rotation, and ensure proper alignment to avoid mechanical damage.
