Barksdale P1H-B340-T,PIH-B340-T Pressure Switch

The Barksdale P1H-B340-T is a mechanical pressure switch from the P1H family that uses a diaphragm-seal piston configuration for reliable sensing in demanding equipment. The B340 designation identifies an adjustable setpoint range of 6 to 340 psi, making it suitable for hydraulic and pneumatic circuits, gas lines, and other industrial systems where precise actuation is required. The device features a compact, rugged body with a standard 1/4" NPT pressure connection and electrical ratings commonly associated with P1H switches, up to 10 A at 125/250 VAC and 2 A at 600 VAC depending on range and wiring configuration. The P1H family offers repeatability of about ±2.0% at a constant temperature, helping maintain consistent switching across temperature changes. Optional materials and enclosures are available in the P1H line, including stainless-steel components and NEMA-rated housings, to match a range of installation environments. The P1H-B340-T variant is designed for industrial pressure monitoring and control, providing a defined, adjustable setpoint and a robust package for high-accuracy pressure switching in critical processes.
