Unique-Bargains 5pcs B50K Potentiometer 50K OHM Linear Taper Knurled Shaft 6mm Electrician Tool

SKU CH-QHY1-3BVW1

Pack of five 50K ohm linear taper potentiometers with 6mm knurled shafts for volume control and electrical device adjustment

  • 50K ohm linear taper suits volume control tasks
  • Knurled 6 mm shaft fits standard knobs securely
  • Top-adjustment design allows quick calibration in place
  • Pack of five supports multiple circuit builds

Pack of Five 50K Linear Potentiometers

This set supplies five B50K rotary potentiometers, each rated at 50K ohm with three terminals and a linear taper. The knurled 6mm shafts fit most standard knobs and allow easy manual adjustment. They are intended for electricians and hobbyists who need multiple identical units for volume controls or similar low-power circuits.

6mm Shaft, 220V AC Rating, Panel-Mount Dimensions

Each potentiometer handles up to 6A at 220V AC, giving ample headroom for typical audio-level or control-voltage tasks. The 13mm shaft length and 7mm mounting thread suit panels of standard thickness, while the 17 by 7.3mm base fits tight enclosures. Builders who need a logarithmic taper, higher power dissipation, or a different shaft diameter will need another component.

Questions about this item

Will the 6 mm knurled shaft fit the standard knobs I already have?

The shaft diameter is 6 mm and the knurled design suits most standard knobs, so existing knobs with a matching bore should fit.

How can I verify the potentiometer is operating correctly after wiring it?

Measure resistance across the outer terminals with a multimeter; it should read close to 50 K ohm, and the wiper terminal should sweep smoothly from one end to the other as you turn the shaft.
