392 Series, RV6 Series 0.5 W Conductive Plastic
Potentiometers
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 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 versions contain an internal shaft seal for moisture
protection and comply 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 1
00 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.
Key Features and Benefits
•
Wave solderable:
Allows the devices to be automatically
soldered on a PCB using the wave soldering process instead
of being manually soldered, saving time and yielding consistent
results
•
PCB washable:
Permits the PCB board containing the soldered
devices to be washed after soldering, saving time and yielding
consistent results
•
•
•
Cost-effective:
Supplies good performance at a reasonable
price
Wide range of resistance values (100 Ohm to 5 MOhm,
inclusive):
Promotes flexibility in the applications
Small package size:
Allows use where space contraints may
be present

Contact 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.
