Backplane Connectors, such as those categorized within Hard Metric, Standard, are utilized in a wide variety of applications. One example is the HM2P88PDA111N9, which is designed for pre-engineered 100 Ohm differential twisted pair (DTP) applications. This particular connector offers excellent electrical performance and low-cross talk characteristics, making it ideal for automotive, aerospace, networking, and other professional applications.

The HM2P88PDA111N9 is a medium-power 133 Amp Hard Metric, Standard backplane connector, designed to meet the needs of data bus applications. The connector is composed of two parts: a connector and a shrouded receptacle. The connector is manufactured from tin-plated phosphor bronze, gold-plated contacts, and stainless steel. The shrouded receptacle is composed of copper alloy and black plastic, designed for a secure connection.

Working principle of the HM2P88PDA111N9 is quite straightforward. The connector has two rows of pin contacts. The contacts are loaded into the backplane connector from a flat ribbon cable, which is only minimally affected by ambient electrical noise. The contact pins search for the correct contact location in the backplane receptacle while the connectors close, ensuring secure connection. When all of the pin contacts have secured with the backplane receptacle, the receptacle locks into the backplane.

The HM2P88PDA111N9 is typically used in automotive, aerospace, and networking applications due to its high electrical performance and low-cross talk characteristics. For power-hungry applications such as in-vehicle networks, the 133 Amp rating ensures that the connector can handle the higher data throughputs. For low noise applications such as aircraft avionics, the backed out construction design reduces signal transmission errors that could result in communication errors.

The design of this type of backplane connector makes it easy to install in the backplane. The contact arrangements allow the complete assembly of the connector and the shroud receptacle to be securely mated with the board version of the connectors. To check the quality of the fit before soldering, the connector can be test fitted using reference jigs. This ensures that there is no misalignment of the contacts or breakage of the pin contacts.

In summary, the HM2P88PDA111N9 is an ideal Hard Metric, Standard backplane connector for applications where exceptional electrical performance, low-cross talk characteristics, and secure lock-in connection are important. The connector has a high power rating, effectively insulates against ambient electrical noise for low-noise applications, and is easy to install.
