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.

392, RV6 Series.
Features: Wave solderable • PCB
washable • Cost-effective • Wide range of
resistance values (100 Ohm to 5 MOhm,
inclusive) • Small package size
Benets: Devices may be automatically
soldered on a PCB using the wave
soldering process instead of being
manually soldered, saving time and
yielding consistent results. The PCB
containing the soldered devices may
be washed after soldering, saving time
and yielding consistent results. Good
performance at a reasonable price. Wide
range of resistance values promotes
flexibility in the applications. May be used
where space constraints may be present.
Potential applications include audio
and visual equipment, light switches,
hand-held multimeters and mobile
monitoring devices, test and measurement
equipment, communications equipment,
thermostats, hand-held medical
equipment and mobile monitoring devices,
medical laboratory and diagnostic
equipment, and vehicle manual controls.
