Series 6D pressure switch Series 6G pressure switch

The Series 6 Pressure Switch is a highly reliable pressure switch for tough applications. Its precision machined aluminum body is anodized for maximum corrosion protection. A polyimide film diaphragm operates a field adjustable switch trip point mechanism attached to a long mechanical life, sensitive differential snap-switch (es), except the 6P where a piston replaces the diaphragms.

All models are weatherproof rated NEMA 4 and 4X, as well as NEMA 7 and 9 for hazardous areas. Models carry Underwriters Laboratories and CSA listing for hazardous locations and explosion proof ratings. Pressure ports are available in either anodized aluminum or stainless steel. Series 6 offers pressure ranges from 3” WC to 5000 psi.
