Bourns PRS14R Rotary Plastic Shaft Dual-Potentiometers

Bourns PRS14R 14mm Rotary Plastic Shaft Dual-Potentiometers offer a small form factor and dual-potentiometer output. The potentiometers include a flatted plastic shaft with either a horizontal or vertical orientation and an optional center tap. 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 PRS14R 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.
