Potentiometers
Line Guide
Potentiometers
convert rotary motion or linear displacement
into a change of resistance, supplying a smooth transition of
voltage or current levels.
The resulting voltage output may be
used to control position transducers in a wide variety of potential
transportation, industrial and medical applications.
Rotary Potentiometers
are compact, rugged, thick-film devices
that use either conductive plastic, or cermet or wirewound
elements. Developed for potential military applications, our
proprietary conductive plastic offers extensive temperature range
and infinite resolution, and is designed to provide precision
position measurement. Cermet and wirewound elements are
stable over a range of operating temperatures and provide
high power dissipation and improved resistance temperature
coefficient.
Linear Potentiometers
feature rugged extruded aluminum
housings to withstand harsh chemicals and immersion in oils
or water. Construction features include extended life PTFE
bearings, precious-metal multi-finger contact wipers, and MystR
®
conductive plastic thick-film elements.
