Plastic Housing | Metal Housing |
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 Enclosure Rating—NEMA 4X rated potentiometers withstand weather, washdowns, and corrosion.
NEMA 6 Enclosure Rating—NEMA 6 potentiometers seal out water from temporary submersion as well as weather and washdowns.
