Application Note
0.5 W Conductive Plastic Potentiometers
392 Series, RV6 Series
Sensing and Control
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 3/8-32 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.
The RV6 Series devices meet requirements of MIL-R-94 and high
grade industry specifications.
These sensors may potentially be used in a variety of
Transportation, Industrial and Medical applications to adjust an
analog signal level via a separate knob or a dial, and as a control
input for an electronic circuit.

392 Series, RV6 Series Key Features and Benets
• 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
MEDICAL
• Mobile monitoring/diagnostic devices (e.g. portable
debrillator): Dial selection (See Figure 7.)
• Laboratory and diagnostic equipment: Dial selection (See
Figure 8.)
TRANSPORTATION
• Vehicle manual controls (e.g., joysticks): Position detection
(See Figure 9.)
