Sauer Danfoss MBC Series Heavy Duty Pressure Switch
Product Introduction
The Sauer Danfoss MBC Series Heavy Duty Pressure Switch, including
models like MBC5100, 3231-1DB04, 061B100266, and 061B023466 (part
of the MBC 5000 Series), is a compact and reliable pressure control
solution designed for industrial and marine applications. Built to
withstand harsh environments—such as machine rooms onboard ships—it
prioritizes space efficiency and durability, making it ideal for
scenarios where reliability and compactness are critical. As part
of Danfoss’ block system (integrating MBC pressure controls, MBS
pressure transmitters, and MBV test valves), it offers seamless
integration with related components. The MBC5100 model, in
particular, holds major marine approvals, ensuring compliance with
maritime standards. With high vibration resistance and accurate
pressure monitoring via a fixed low differential, it is suitable
for alarm indication, shutdown, control, and diagnostics across
diverse equipment like motors, pumps, compressors, and more.
