0746499002

The 0746499002 is a special type of backplane connector designed for applications that require a high-density and high-speed inter-connect. It is commonly used in applications such as servers, switches, and other networking devices. This connector is available as either an unshielded or shielded version. Both versions have similar features and uses.

Connector Overview

The 0746499002 is a type III, 4 row x 4 column connector with a pitch size of 0.80mm. It has a total of 52 contacts, with 49 signals, 2 power, and 1 ground. The shrouded design of the connector increases mating accuracy and suitability for high-density applications versus other backplane connectors. It is available in 7, 8, 10, and 12 contact configurations with contact counts ranging from 40 to 64. The connector system offers high-speed differential performance up to 20 Gb/s pin speed.

Application Field

The 0746499002 is typically used in data center and high-speed network applications. Its high-density design enables it to be use in densely populated backplane environments. Due to its small size and high performance capabilities, the 0746499002 is suitable for a variety of applications including switches, routers, servers, storage, and HPC environments. The shielded version has improved EMI/RFI capabilities which makes it especially suitable for applications that require higher levels of electromagnetic and radio interference mitigation.

Working Principle

The 0746499002 is an interference-fitting connector. The simplest form of interference fitting is where friction holds the parts together without any external fasteners. When mated, the two halves of the connector come into contact and form a relatively tight fit. The fit is measured in terms of ‘dimensional interference’ which is the difference between the diameters of the two parts. The greater the dimensional interference, the tighter the fit. The tightness of the fit is important as it ensures that the connector remains securely mated and minimizes electro-magnetic interference. As the two halves come together they form an interference fit which also forces the grounding contacts to make contact which helps to dissipate EMI/RFI.

Conclusion

The 0746499002 is a high-density, high-speed backplane connector designed for use in a variety of applications. It is available as either an unshielded or shielded version and is suitable for use in high-speed and dense backplane environments. It offers superior dimensional interference to ensure a tight fit and improved EMI/RFI protection. The combination of dimensions and the tight fit it offers make the 0746499002 an ideal solution for applications that require a high-speed and high-density inter-connect.
