The MDB1-51PCBRP D-Sub Connectors Application Field and Working Principle

The MDB1-51PCBRP, manufactured by NMB-Minebea Ltd, is a cost-effective, robust and reliable D-Subminiature (D-Sub) connector that is used predominantly in custom and general-purpose applications. It is the Z-direction mating connector to the PC50B, and can accommodate up to 1.6A current and has a contact resistance of 20 mΩ max.

D-Sub Connectors, which are also known as D-Subminiature Connectors, are a type of electrical connector that is small and rectangular in shape. It is often used for computer and electronic applications, as well as for automative, industrial and telecommunications applications. These connectors provides power and signal conduction between two ports or components.

Features

• Mates with PC50B connector
• Mating force of 2.0N/2.0N min.
• Operating temperature range of -30 to +85°C
• Insulator material is UL94V-0 rated thermoplastic.
• UL recognition, CSA approval, and RoHS compliance.

Application Field

The MDB1-51PCBRP D-Sub Connector is primarily used in computer power supplies, where a higher voltage current is needed. It is also often used in high-speed data processing, digital logic circuitry, HDMI ports, audio / video cables, serial and parallel ports, and telecom modems. Additionally, it is applicable in automotive, industrial, and medical fields, such as powertrain engines, automotive monitoring, and diesel pumps.

Working Principle

The MDB1-51PCBRP D-Sub Connector has a pin contact design which enables a secure and reliable connection. It has an integral contact pin which is locked in place by a small metal cag；when a male D-subminiature connector is inserted into it, the metal cage is forced downwards which then pushes the contact pin out to make a connection. The contact pin is made from copper alloy, and the insulator material is UL94V-O rated thermoplastic.

The MDB-51PCBRP connector meets the PC-51 precision interface requirements and allow for reliable contact and minimal signal losses. Its receptacle is also robust and has a heat-resistance of +85°C. The contact resistance of up to 20 mΩ max ensures a reliable and safe connection.

Conclusion

The MDB1-51PCBRP D-Sub Connector is an economical and highly reliable connector. It is a strong and durable, low-cost solution for applications in computer, automotive, industrial, and medical fields. It has a pin contact design, which allows for a secure connection and minimal signal losses. Its receptacle is robust and has a heat-resistance of +85°C, and the contact resistance of up to 20 mΩ max ensures a reliable and safe connection.
