Danfoss MBC 5100 Block-Type Marine Pressure Switches

Product Overview:

The Danfoss MBC 5100 is a block-type pressure switch specifically engineered for the most demanding marine and heavy-industrial applications. Its vibration-stable construction allows for direct mounting on hydraulic manifolds, making it the premier choice for engine room monitoring, pump group control, and compressor system protection. Part numbers 061B001066 and 061B100466 are certified by nearly all major ship classification societies, including DNV, LR, ABS, and BV, ensuring high-precision electrical contact switching even under severe physical shocks and extreme thermal variations.

Featured part numbers: 061B001066, 2431-1DB04, and 061B100466.

Key Technical Advantages:

• Superior Vibration Stability: The unique block-type mechanical architecture ensures that switching points remain stable even under continuous vibration loads up to 4g, outperforming traditional pipe-mounted switches.

• Global Marine Certifications: Fully compliant with DNV, LR, ABS, BV, and RINA maritime standards, suitable for ocean-going vessels, offshore platforms, and industrial heavy machinery.

• Precision Bellows Design: Utilizes a high-quality bellows principle to ensure exceptional repeatability and minimal hysteresis drift over a long service life.

• Compact Integration: The block design facilitates flange connection, significantly reducing the installation footprint in complex power units and integrated manifolds.
