SUCO
The SUCO 0H86 (diaphragm type) and 0H87 (piston type) are SPDT changeover mechanical pressure switches designed specifically for hydrogen applications. Built with a 316L stainless steel hex‑27 housing and EPDM diaphragm (0H86) or piston mechanism (0H87), they operate up to 250 VAC/DC. Their adjustable pressure ranges start from 0.5 bar and extend up to 200 bar, and they offer exceptional overpressure safety, up to 700 bar in select variants, for added protection against transients. These models include factory-set hysteresis and utilise reliable silver contacts, ensuring stable, long-term switching performance in critical environments.
These hydrogen-compatible switches are ideal for high-pressure gas systems, fuel cell installations, and industrial hydrogen storage or dispensing stations. Their hydrogen-ready design enables safe pressure monitoring and automatic control while maintaining integrity in potentially explosive atmospheres. The choice between diaphragm and piston sensing allows adaptability depending on media cleanliness and pressure ranges, making them suitable for applications in mobility (e.g., hydrogen refuelling vehicles), petrochemical, or hydrogen generation setups. With robust construction, excellent overpressure resilience, and hydrogen certification, the 0H86/0H87 series provides a reliable, precise, and safe solution for industrial hydrogen pressure control systems.
