Application Note 0.5 W Conductive Plastic Potentiometers 392 Series, RV6 Series Background Potential Applications Potentiometers convert rotary motion into a change of resistance, INDUSTRIAL/COMMERCIAL supplying a smooth transition of voltage or current levels. Audio and visual equipment (e.g., guitars, sound The resulting voltage output may be used to control position mixers, projectors): Volume, tone, brightness, contrast, transducers in a wide variety of potential applications. and other signal controls (See Figure 1.) The 392 Series and RV6 Series 0.5 W Plastic Potentiometers are Light switches: Dimmer control (See Figure 2.) economical devices designed to meet wave soldering process Hand-held equipment (e.g., multimeters and mobile requirements for mounting to printed circuit boards (PCBs). All monitoring devices): Dial selection (See Figure 3.) versions contain an internal shaft seal for moisture protection and Test and measurement equipment (e.g. oscilloscopes): comply with PCB washability test requirements and MIL-R-94 Signal control, dial selection (See Figure 4.) standards where appropriate. Termination types are PC pin or Communications equipment (e.g. walkie-talkies): Dial solder hook, both are solder-dipped. selection (See Figure 5.) These small, single turn devices have a 3,18 mm 0.125 in Thermostats: Dial selection (See Figure 6.) 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 Figure 1. Sound mixer Figure 2. Light switches antilog to meet a wide range of application requirements. The RV6 Series devices meet requirements of MIL-R-94 and high grade industry specifications. Solutions 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 Figure 3.
