Potentiometers

Potentiometers — New & Used

Potentiometers (variable resistors) are essential components for controlling voltage and signal levels in circuits. Used in industrial automation, motor control, instrumentation, and audio systems, they provide smooth and precise resistance adjustment. Available in rotary, linear, and multi-turn configurations, potentiometers deliver reliable performance for calibration, tuning, and user interface control.

At Surplus Select, we carry a dynamic inventory of new and used potentiometers from trusted OEMs like Bourns, Allen-Bradley, Honeywell, Spectrol, Clarostat, and Vishay. Our inventory updates daily, offering surplus pricing on high-quality variable resistors for electronics repair, MRO, and OEM production use.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.
