COMPACT "PB" SERIES POTENTIOMETER
Janco
has developed a unique solution for combining rotary switches and potentiometers
to save space and weight. The design approach is innovative because the
potentiometer is an integral part of the rotary switch and visually appears
as just another switch deck. The switch and potentiometer can be controlled
independently via a concentric shaft arrangement. Prior to this design breakthrough,
the only way to achieve this combination device was to piggyback a separate
potentiometer onto the back of the rotary switch. This approach necessitated
significant mounting hardware to hold the assembly together and some type
of linkage between the two parts, impacting size, weight and potentiometer
shaft play. Features:
- High reliability
- Custom configurable from 1 to 50K ohms resistance
- Custom configurable stops
- Pots may be stacked similar to rotary switch decks
- Various mounting methods available
- Rotational torque is custom configurable
- Environmentally sealed construction
- Pots may be stacked with Janco 13M series rotary switches for switch/pot combination
- Total resistance tolerance: +/- 10%
- Independent linearity: +/-0.25%
- Power rating: .50 watt max @ 70 degrees C
- Effective electrical travel: 340 degrees max.
- Mechanical travel: 350 degrees max.
- Meets environmental requirements of MIL-S-3786
