Backplane connectors, most commonly recognized under the terms of VME, CPCI, VXS, and VPX, refer to standardized group of components that keep the main motherboard or backplane connected to numerous other boards or peripheral cards. The M39029/11-144 contact is a perfect example of the smallest designated type of high density interface contact available for backplanes. This article will cover the application field and working principle of the M39029/11-144 contact.

Application Field

The M39029/11-144 contact is used on connector systems for high frequency, high density, and high speed applications. It is designed to meet a wide range of industry standards including the VME P1 single row system, the P2 dual row system, the RH1 and RH2 types from the CPCI specification, and the VXS/VPX standard. It is also compatible with numerous other backplane designs, including legacy designs which feature conventional two-piece shells and insulated board-to-cable systems.

The M39029/11-144 contact is used in highly demanding applications where a high level of performance and reliability are required. These applications range from the most sophisticated aircraft systems to the most advanced telecom routers, mobile base stations, and similar equipment for defense and other industries. Due to its versatility and reliability, the contact can also be found in networks of varying complexity, such as LANs, WANs, and Metro Ethernet networks.

Working Principle

The terms “working principle” and “function” are often used interchangeably, but in the case of the M39029/11-144 contact, they are two distinct concepts. The fundamental function of the contact is to provide a secure and dependable connection between the backplane and the various peripheral cards or boards mounted within the system. This is achieved through a unique design that features a series of internal guide pins and a spring that is mounted to the contact itself.

The M39029/11-144 contact works by guiding the contact pin on an incoming peripheral card into the contact\'s opening. At the same time, the spring applies pressure against the ground portion of the contact, providing a tight and secure connection. This ensures that the connection between the two devices remains stable and reliable even when exposed to a variety of shock and vibration events.

In addition to the contact\'s robust design, the M39029/11-144 contact also has excellent performance and reliability characteristics. This includes a nominal current rating of 5A, a maximum operating temperature of up to 125°C, and a contact resistance of less than 2.5 milliohms. The integrated shielding helps ensure EMI/RFI immunity while still providing an acceptable degree of flexibility.

Conclusion

The M39029/11-144 contact is a small but reliable contact, designed for high density, high frequency, and high speed applications. It provides a dependable connection between the backplane and other peripheral boards or cards, and is capable of withstanding a wide range of shock and vibration events. It also has excellent performance and reliability characteristics, making it an ideal choice for a range of backplane designs.
