Barksdale VCD1H-H18SS Vacuum Switch

The Barksdale VCD1H-H18SS Vacuum Switch is a single-setpoint housed diaphragm switch designed for reliable vacuum sensing in industrial controls. Encased in a NEMA 4 housing, it is built for rugged environments and easy installation in control panels, with an SPDT contact arrangement suitable for safety interlocks and automation circuits. The model covers a vacuum actuation range from 0.06 to 30 inches of mercury (inHg) and carries ratings of up to 10 A at 125/250 VAC and 3 A at 480 VAC. The -18SS suffix indicates a stainless-steel wetted-parts variant of the VCD1H family, offering improved corrosion resistance in demanding environments. This switch is commonly used to monitor vacuum levels in pumps, compressors, vacuum systems, and process equipment, delivering a compact, pre-wired housed solution for reliable operation in industrial applications.
