Harsh Environment Potentiometers
Rated NEMA 4X and 13, these potentiometers are protected from debris, washdowns, and oil/coolant spraying. Also known as variable output switches or rheostats, they vary electrical flow to control speed, volume, and light intensity.

Potentiometers
Vary electrical flow to control speed, volume, and light intensity. The number of turns affects the resolution—the higher the number, the better the control. Also known as variable output switches or rheostats. A knob is required (not included).
Switches with ball bearings have a smoother rotation and a longer service life than other potentiometers.

Digital Potentiometers
More precise than analog potentiometers, these have a three-digit display that is easy to read. Also known as variable output switches or rheostats, they vary electrical flow to control speed, volume, and light intensity.

Variable-Speed Foot Switches
When the pedal is pressed, the built-in potentiometer adjusts the resistance to vary the speed for motor drives. These switches can be wired to either increase or decrease the current when actuated. All are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.
