Barksdale's P1H-J600 Pressure Switch is a Dia‑Seal piston mechanical pressure switch designed for long‑life pressure control in hydraulic and pneumatic systems. Setpoints are adjusted via an external front screw, it uses a standard 1/4" NPT female process connection, and it features a single SPDT snap‑action contact; the enclosure is anodized aluminum and rated to NEMA 4 and 13. The unit is available in hazardous-location variants (Ex ia and UL‑listed) and is designed for millions of maintenance-free, leakage-free cycles. Common applications include hydraulic and pneumatic control loops and shipbuilding, and the P1H family is capable of controlling pressures up to 1600 psi.
