Bourns PRS12R 12mm Rotary Metal Shaft Dual-Potentiometers

Bourns PRS12R 12mm Rotary Metal Shaft Dual-Potentiometers feature a very small form factor and offer dual-potentiometer output. Options for the potentiometers include an optional center detent, horizontal or vertical orientation, and flatted, knurled, or slotted shafts. The THT mounting type devices operate in a -10°C to +70°C temperature range with a 0.05W power rating and 5kΩ to 500kΩ standard resistance range. The PRS12R components are designed for use in professional audio and lighting applications, low/medium risk medical and laboratory equipment, industrial automation and control, and other applications where a reliable potentiometer is required.
