2170291-2

Backplane Connectors, such as the 2170291-2, are electrical connectors used for the purpose of attaching circuit boards to a backplane. This type of backplane connector is often referred to as “Hard Metric” as it is designed to meet specific quality and accuracy needs. Many of these Hard Metric connectors are designed to an international standard allowing them to be used on multiple applications.

The 2170291-2 is a versatile backplane connector designed to meet most demanding performance and reliability requirements. It is available in 25 to 400 pin contact styles. The connector has a 5/5th pitch, which is more reliable than a 6/6th pitch, and provides superior signal transmission. It also features a reinforced low insert force design that offers high reliability and a longer mating life.

This connector also offers a standard polarization option that helps ensure proper mating orientation. It includes several features that improve EMC performance, including an optional EMI/RFI finger and a brass shell combined with an aluminum alloy to help improve grounding and shield effectiveness. The connector also features an unusual design that uses a tapered pin to increase contact reliability. This unique design also ensures that the contacts remain properly aligned and that a positive electrical connection is maintained.

The 2170291-2 also offers a wide range of performance options. It features an optional flat ribbon design that reduces the power consumption associated with serial data transfer. Additionally, it can be used in high-speed applications, such as Ultra SCSI, and can operate up to 100MHz with a maximum throughput of 160 Gbps. It also offers extended temperature ranges, improved signal integrity, and enhanced noise rejection.

In terms of working principle, the 2170291-2 provides a robust mechanical connection between two boards, known as the backplane board and the plug-in board. The backplane board provides power and connection points to the plug-in board. The plug-in board is placed on top of the backplane board and the connector is mated with contact housing on the backplane board. On the plug-in board, the contact housing is mated with the connectors on the connector. The mated connectors form the electrical connection path, providing a low resistance path for current to pass between the two boards. This allows for data transmission between the two boards.

The 2170291-2 is a reliable backplane connector designed for a wide range of applications. It features an advanced design which provides superior signal transmission, improved EMC performance, and extended temperature ranges. Additionally, it is designed for high-speed applications and offers a wide range of performance options. With its proven reliability, the 2170291-2 is an ideal choice for any backplane connector.
