Potentiometers, Rotary (Conductive Plastic)

Curtiss-Wright, Sensors Division's conductive plastics rotary potentiometer provides unsurpassed precision and reliability with maximum space economy. Our developed conductive plastic track is a thin conducting film with a hard, wear resistant surface, which together with a multiple contact wiper configuration, ensures that our potentiometers offer virtually infinite resolution, long life and a low noise characteristic. These potentiometers maintain performance in severe environmental conditions. Particularly in the conditions of vibration, temperature and shock found in civil and military aircraft, and naval vessels.

In addition to long life and the performance reliability features, our conductive plastics technology also provides inherent integrity in that should a small part of the track be damaged, the remaining track is still operative. Such damage is easily monitored and cannot cause catastrophic systems failure.

Multi-cup potentiometers can be supplied having tight voltage tracking error tolerances for use in monitoring multiplex systems.
