GENERAL INFORMATION
Potentiometers convert rotary motion into a change of resistance,
supplying a smooth transition of voltage or current levels. The result-
ing voltage output may be used to control position transducers in a
wide variety of potential applications.
The 392 Series and RV6 Series 0.5 W Plastic Potentiometers are
economical devices designed to meet wave soldering process
requirements for mounting to printed circuit boards (PCBs). All ver-
sions contain an internal shaft seal for moisture protection and com-
ply with PCB washability test requirements and MIL-R-94 standards
where appropriate. Termination types are PC pin or solder hook,
both are solder-dipped.
These small, single turn devices have a 3,18 mm [0.125 in] diameter
shaft that is available in a range of lengths. Most configurations have
either a standard or split locking 1/4-32 NEF-2A bushing in panel seal
or no panel seal versions. The shaft/bushing materials are nickel-
plated brass or thermoplastic. They are available in metal/metal,
plastic/plastic or a combination of the two. Custom designs are
available upon request.
The 392 Series and RV6 Series are available in resistances from 100
Ohm to 5 MOhm, inclusive. Tapers include linear, log, and antilog to
meet a wide range of application requirements.
RV6 Series devices meet requirements of MIL-R-94.

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.
