HEAVY DUTY LIMIT SWITCHES

Stainless steel

HDLS

HDLS stainless steel switches are designed for use in highly corrosive environments such as petro- chemical plants, food processing plants, shipboard and dockside locations. The type 316 cast stainless steel body is designed to minimise crevices where food particles could become trapped. The actuator, operating head and screws are also stainless steel. All seals are Fluorocarbon to provide excellent chemical resistance and to withstand operating temperatures up to 121 °C (250 °F) and pressurised steam cleaning.

Approvals:	NEMA 1, 3, 3R, 4, 4X, 6, 6P, 12, 13
			UL, CSA, CE
Operating temperature:		-12 °C to 121 °C
		10 °F to 250 °F
Contacts:	Electrical ratings A, B		Silver

Levers: Levers for side rotary types are ordered separately (see pages 69-71 for details)
