Backplane Connectors - Specialized: The 72394-221 Application Field and Working Principle

The 72394-221 is a special type of backplane connector that is designed to provide enhanced flexibility in high-speed, high-performance data transmission soltuions. It is well suited for applications requiring high-bandwidth, low-latency connections and robustness in high-temperature, small-footprint applications. It is commonly used in ground-based avionics systems, portable electronic instrumentation, aerospace and defense systems, and medical applications.

The 72394-221 backplane connector is a product of Molex Incorporated and is designed under their patented "TM4" technology. This technology is designed to provide high-performance data transfer capabilities, meet stringent reliability requirements, and maximize signal transmission integrity. This technology has been recognized for its innovation in allowing for easier interconnectivity between disparate, high-performance systems.

The 72394-221 is a 30-position, 50-contact, edge-mount type backplane connector. Its base material is aluminum and its mating connector is Molex\'s "TM4" series and its integral grounding surface is constructed of nickel-plated zinc. It is rated to operate at up to 11A and is designed to support data communication speeds up to 2.4Gbps.

The connector consists of a single-piece back shell that provides shielding against electromagnetic interference (EMI) and additional protection against accidental contact during assembly. The integrated ramp-shaped contact elements provide reliable mating and robust working between the sides of the contacts, preventing excessive friction to ensure secure connection. The integral grounding of the contact surface also ensures maximum data transfer integrity.

The 72394-221 features 50 dual-row contacts on a 30-position pitch, allowing for easier and faster installation of backplane connectors. These contacts are spring-loaded to ensure electrical connections are maintained even when subjected to vibration and shock. Furthermore, these mating connectors feature a dust-cap design that protects contacts from dust build-up, ensuring longer connection and data transfer longevity.

The 72394-221 backplane connectors also offer the versatility of accepting certain snap-tray replacement covers, allowing them to be mounted in the same space but changing the contact pattern or the height of the connector. It is compatible with many Molex and third-party backplane adapters, allowing for a range of connection possibilities.

In summary, the 72394-221 backplane connector is a highly specialized connector offering an increased signal-to-noise ratio, greater data transfer speed, reliability, and robustness compared to traditional backplane connectors. Its cutting-edge technology and versatile design makes it ideally suited for high-speed, high-performance data communication applications.
