Danfoss MBC 5100 & MBC 5000 Block-Type Pressure Switches

Product Overview:

The Danfoss MBC series of pressure switches are engineered specifically for demanding marine and industrial applications where space is at a premium and reliability is non-negotiable. The MBC 5100 features extensive global marine approvals, and its block-type design allows for direct mounting on hydraulic manifolds, offering superior vibration stability. Whether for engine room monitoring (061B100166 / 4241-1CB04) or general industrial pressure sensing (061B201266 / 1011-1CB04), this series provides precise, long-life electrical switching protection even under severe shocks, pump vibrations, and extreme temperature cycling.

Featured models and part numbers: 061B100166 (MBC 5100-4241-1CB04) and 061B201266 (MBC 5000-1011-1CB04).

Key Technical Advantages:

• Extreme Vibration Stability: Designed specifically for mobile machinery and marine engine rooms, the unique block-type architecture withstands continuous vibration loads up to 4g, far outperforming standard pipe-mounted switches.

• Global Marine Certifications: The MBC 5100 is fully compliant with DNV, LR, ABS, BV, and RINA standards, making it the designated component for marine main engines, auxiliary engines, and propulsion systems.

• Precision Bellows Control: Utilizes high-quality stainless steel bellows to ensure high repeatability and minimal hysteresis drift over long-term operation.

• Compact Integration: Supports flange connection for seamless integration with MBV 5000 test valves, significantly saving wiring and installation space within hydraulic power units.
