Product features
A carrier plate uses adaption to make a positive fit on the shaft clamp (damper actuators) or on the
position indication (rotary actuators) and transfers the position directly to the feedback potentiometer.
Mode of operation
Technical data sheet P1000A

The feedback potentiometer unit is used for modulating damper control in connection with controllers
with fixed feedback. The feedback potentiometers can also be used in conjunction with commercially
available systems for damper position indication or as positioners for parallel running actuators.
The feedback potentiometers are attached directly by the shaft clamp (damper actuators) or on the
position indication (rotary actuators). The guiding grooves between the housing and the switch ensure a
tightly sealing fit.
