Backplane Connectors - Hard Metric, Standard, are specific types of electrical backplane connectors designed to offer superior performance in terms of speed, power, and reliability over other types of backplane connectors. HM2P40PDW145N9LF connectors are a type of Hard Metric backplane connector, specifically, that ensure faster connection speeds, improved power efficiency, and increased reliability. Such connectors are typically employed in telecommunication, consumer electronics, and high-speed data communications applications.

HM2P40PDW145N9LF connectors are based on a unique hard metric design, or “Hard Metric+” as they are sometimes called, and feature two types of signal contacts: pins and sockets. The pin contacts are arranged in rows and are 14mm apart while the sockets are arranged in pairs and are approximately 3.5mm apart. The contacts are also coated in a corrosion resistant material, which further enhances their durability.

The pin contacts contain two-hubs and are used to transmit digital signals over the backplane. The socket contacts are responsible for power, typically up to 16A. The number of signal pins and power terminals may vary depending on the required performance. However, HM2P40PDW145N9LF connectors usually feature 40 signal pins, arranged in 8 rows of 5 contacts, and 4 socket power terminals, with a minimum distance of 35mm between them.

The most important feature of HM2P40PDW145N9LF connectors is their high resistance to EMI interference and crosstalk. This is done by providing an air gap between the signal and power connections, as well as through the use of specific shield material that inhibits the absorption of EMI radiation. This greatly improves the quality and reliability of the connection.

The electrical principles of HM2P40PDW145N9LF connectors revolve around the use of a differential signal transmission technique. In this type of signal transmission, each signal is split into two different signals and they are sent out on different lines. Then at the receiver, the signals are recombined in such a way that any interference is eliminated. By splitting the signal in this way, the speed of signal transmission is increased, reducing the risk of crosstalk and providing an overall improvement in signal quality.

Overall, HM2P40PDW145N9LF connectors offer superior performance compared to other types of backplane connectors. They provide faster connection speeds, improved power efficiency, increased reliability, and better resistance to EMI interference and crosstalk. As a result, these connectors are suitable for a wide range of applications, including telecommunication, consumer electronics, and high-speed data communications.
