Bourns PRS11R 11mm Rotary Metal Shaft Potentiometers

Bourns PRS11R 11mm Rotary Metal Shaft Potentiometers feature a very small form factor, offer an optional momentary switch, a flatted shaft style, and a -20°C to +70°C operating temperature range. Variations in the PRS11R potentiometers include horizontal/rear-facing or vertical/side-facing orientations, shaft lengths (15mm, 20mm, or 25mm), switch configuration (no switch or push momentary switch), and resistance tapers. The Bourns PRS11R 11mm Rotary Metal Shaft Potentiometers are designed for use in professional audio and lighting applications, low/medium risk medical* and laboratory equipment, industrial automation controls, and other applications where a reliable potentiometer is required.

*Bourns® products have not been designed for and are not intended for use in “lifesaving,” “life-critical”, or “life-sustaining” applications nor any other applications where failure or malfunction of the Bourns® product may result in personal injury or death. See Legal Disclaimer Notice:
