Cable entry: Single 3/4"-14 NPT threaded conduit entry
Housing color: Alert Orange
Housing material: Cast iron
Shield: Oversized cast aluminum shield
Switch connections: Solder terminal or quick-connect terminal
Electrical ratings: 15 A, 125–250 VAC; 1/2 HP at 125–250 VAC
EnclosureNEMA Type 1, 2, 4, 13; UL enclosure Type 1, 2, 4, 13; EN 60529 degree of protection; IP56 standard, IP68 upon request
PurposeO-shield design provides drip-tight, dust-tight, watertight and oil-tight protection for harsh industrial environments
Features & Benefits- Rugged cast metal housing provides weight and stability to prevent sliding during operation
- Neoprene cover gasket and O-rings on the activating shaft; separate ground screw for safe earthing
- Three mounting holes for rigid installation to floor or equipment
- Specify maximum resistance value to match application requirements
Materials- Treadle and housing constructed from cast iron for mechanical strength
- Oversized cast aluminum shield for added protection
- Painted Alert Orange for visibility
- Standard single 3/4"-14 NPT threaded conduit entry
- Designed for use with variable-speed motor drives; available in selected 2 W linear values
- Treadle is spring-loaded and returns to normal position when released; depressing the treadle rotates potentiometer from zero to selected maximum
- Auxiliary contact (optional) rated 15 A, 125–250 VAC; up to three SPDT switches can be added and adjusted to operate at any point in treadle travel
