What is the MDM-25SBR?

MDM-25SBR is a type of special purpose connector developed by Molex and designed to perform a variety of specialized functions while operating in harsh environments. It has a unique mating system that system allows for increased reliability and durability in extreme conditions. MDM-25SBR is part of the Molex D-Sub family of connectors, which are used to connect circuits and electronic devices to components, such as switches, displays, and cables.

Typical Application

MDM-25SBR is a reliable and durable connection solution for automotive, power-converter,and industrial applications where highly configurable interconnect solutions are needed. It is designed with an innovative mating system that can operate in extreme temperatures and resist harsh environmental conditions such as shock, vibration, temperature flux, and corrosive elements. Its features make it a desirable choice for a wide range of applications, including HVAC, military, power grid, and aerospace.

Product Advantages

MDM-25SBR can achieve higher vibration and shock resistance because of its unique helix contact system and compact-groove construction.The connectors support up to 15A of DC current and have a high temperature rating of up to 250°C. This extreme temperature rating makes them suitable for high temperature applications.The MDM-25SBR also provides complete air and water tight seals between connectors to prevent water and dust ingress and increase the lifespan of the product. The connectors are IP67/IP68 rated and operate up to 10A. The contact design also provides high signal integrity, low EMI, and greater design flexibility.

Working Principle

The MDM-25SBR is a blind-mating, small-form-factor, and dual-row connector featuring a plastic shell material. The unique contact system incorporates a four-part, helical-design contact. This contact provides robust connections when mated with the one-piece, guided header and springs to ensure continuous contact with the communicating device.The MDM-25SBR pins are all insulated with UL-rated heat shrink. The insulation helps to protect against potential electrical shocks and provides a secure connection. A soldertail engagement system helps further protect the pins from environmental contaminants and mechanical damage during installation. Finally, the four-point contact system prevents solder-drip, which helps ensure a reliable connection.

Conclusion

The MDM-25SBR is a reliable, high-performance connector designed to meet the demands of harsh environments and extreme temperatures. It is rated up to 15A and offers superior protection against moisture and dust. Its four-point contact system ensures a reliable connection with zero solder-drip, while the insulation provides high signal integrity and low EMI. All of these features make the MDM-25SBR an ideal solution for numerous industries such as automotive, military, and aerospace.
