Barksdale VCD1H-H18SS Diaphragm Pressure Switch

The Barksdale VCD1H-H18SS is a housed diaphragm pressure switch with a stainless-steel diaphragm and a single preset contact, designed for compact installation in control panels. It uses a 1/4" NPT pressure connection and SPDT output, rated for 10 A at 125/250 VAC and 3 A at 480 VAC, all inside a NEMA 4 enclosure for reliable operation in damp or dusty environments. The unit is a single-setpoint housed switch (VCD1H family) with a setpoint range of 0.8 to 30 inches of water column (W.C.), enabling both vacuum and low-positive-pressure sensing. The stainless-steel diaphragm (18SS) and rugged housing contribute to durability in challenging environments, making it suitable for use in applications requiring precise diaphragm-based switching in enclosed equipment or control panels. The 18SS designation indicates stainless-steel diaphragm construction that resists corrosion and humidity, supporting longevity in demanding installations.
