Product Overview

The Danfoss MBC 5100 series compact pressure switches (models: 061B100566 / 061B010466 / 061B100166 / 061B100466 / 061B110466) feature a modular block design, specifically engineered for marine and industrial applications where space constraints and reliability are paramount. Manufactured in strict compliance with ISO 228-1 standards, these units offer G1/4″ pressure connections and IP65-rated enclosures, with stable operation across a wide temperature range from -40°C to +85°C.

As a core component of Danfoss’ industrial sensing solutions, the MBC 5100 series serves as a direct drop-in replacement for original OEM units. With exceptional shock and vibration resistance, these pressure switches are widely deployed in refrigeration, air conditioning, compressors, boilers, steam systems, and water booster applications. Every unit undergoes 100% simulated in-service testing to ensure it meets design performance targets immediately upon installation—no additional calibration required.

Interchangeability Note: All five models belong to the MBC 5100 series, sharing identical interface dimensions, electrical connection standards, and mounting configurations (G1/4″ port, DIN plug, PG11/PG13.5 electrical connections), enabling seamless replacement within same-series applications.

Key Technical Advantages

1. Modular Block Design with Exceptional Shock & Vibration Resistance
The MBC 5100 series incorporates Danfoss’ patented compact block design, with highly integrated internal components and rugged construction that withstands high-frequency vibration and mechanical shock in marine and industrial environments, significantly extending service life.

2. Wide Pressure Range Coverage for Diverse Applications
With regulation ranges spanning from -0.2 bar to 100 bar across five models, the series accommodates everything from low-pressure vacuum monitoring (061B010466) to medium-to-high pressure hydraulic systems (061B100166). Fixed differential design with low minimum differential values (as low as 1 bar) ensures precise and stable switching points.

3. Full Environmental Adaptability with IP65 Protection
All models feature IP65-rated enclosures, providing complete dust protection and protection against low-pressure water jets. With an operating temperature range of -40°C to +85°C, G1/4″ standard interfaces, and multiple electrical connection options (PG11/PG13.5), these switches perform reliably in extreme cold, high temperature, and high humidity conditions.

4. Globally Certified for Regulatory Compliance
The product line holds over a dozen international certifications including ABS, BV, CCC, CCS, CE, DNV, GL, LR, and RoHS, meeting marine classification society requirements, pressure equipment directives, and environmental compliance standards—making them the trusted choice for global OEMs and end-users.

5. SPDT Contacts for Flexible Control
Standard single-pole double-throw (SPDT) contacts support both normally open and normally closed output configurations. With contact ratings of AC15 = 0.5 A / 250 V and DC13 = 12 W / 125 V, the switches can directly drive small relays or PLC digital input modules.

Application Areas

General Application Fields: Shipbuilding and marine maintenance (MBC series specifically designed for marine applications), industrial refrigeration and air conditioning, compressors and pumping stations, boilers and steam systems, water booster systems, hydraulic and pneumatic control systems.

Expert Maintenance Tips

1. Mounting Orientation and Position
Vertical installation with the pressure port facing downward is recommended to prevent contaminants or condensate from accumulating in the diaphragm sensing chamber, which could affect switching accuracy. Use thread sealant or PTFE tape to ensure a leak-free seal at the G1/4″ connection.

2. Electrical Connection Practices
Electrical connections utilize DIN plugs conforming to EN 175301-803-A standards. Always verify power is disconnected before wiring. Follow SPDT contact markings (COM / NO / NC) precisely. Shielded cables with proper grounding are recommended to prevent electromagnetic interference-induced false triggering.

3. Set Point Adjustment
The MBC 5100 series features factory-preset pressure switches with fixed differential. If field adjustment of the set point is required, use the dedicated adjustment tool and verify the switching point against a calibrated pressure source after adjustment. Functional verification every 12 months is recommended.

4. Environmental Protection
Although the product operates reliably from -40°C to +85°C, avoid direct exposure to rain or chemically corrosive media. In marine applications, additional protective covers are recommended to guard against salt spray corrosion.

5. Compatibility Notes
When replacing older pressure switches, verify the original system’s pressure connection type (G1/4″ or other specifications) and electrical connection size (PG11 or PG13.5). All five models in this series share identical interface and mounting dimensions, enabling true drop-in replacement without system modifications.
