GENERAL INFORMATION
Potentiometers convert rotary motion 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 applications.
The five series listed below are all 2 W plastic potentiometers and
are available in resistances from 100 Ohm to 5 MOhm, inclusive.
Available tapers include linear, log, and antilog to meet a wide
range of application requirements. These single turn devices
have a 6,35 mm [0.250 in] diameter shaft that is available in
a range of lengths. Most shafts are nickel-plated brass. Most
configurations have a standard 3/8-32 NEF-2A bushing; a high
torque version is also available. Termination types are solder lug
(with or without a center tap), PC pin or fast-on, all are solder-
dipped. Custom designs are available upon request.

1Contact resistance variation is the maximum momentary change in contact resistance that occurs when the wiper is moved from one
location to another location. The larger this change, the more difficult it is to set the trimmer potentiometer and the more unstable the
long term setting will be.
