Precision Potentiometers
Control a device with 10 times the precision as our standard potentiometers. With a resolution of 0.1% or less, these potentiometers fine-tune an electrical flow, so you get the exact brightness, loudness, or speed you need. For example, use them to control the speed of a conveyor so packages move at just the right pace for labeling. Unlike standard potentiometers, confirm your settings on the display. Also known as variable output switches.

Harsh Environment Potentiometers

Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.
NEMA 4X rated potentiometers withstand weather, washdowns, and corrosion.

Heavy Duty Light Dimmers

Often used with high-wattage lights, an external heat sink prevents these dimmers from overheating. They stick out from the wall 1/2 in. to help them disperse heat.
