77428-144LF Connectors, Interconnects

Backplane Connectors - Contacts are used to transmit data between components in an electronic system, most commonly through a centrally mounted connector. The 77428-144LF connector offers higher data rates than larger connectors, making it ideal for space-restricted and board-level installations. It is designed to meet the requirements of networking, storage, medical, and industrial control applications. This article will discuss the application field and working principle of 77428-144LF.The 77428-144LF, a high-performance, robust, and low profile I/O connector, is a perfect choice for applications where board-level I/O connections are required. It is an ideal solution for system designers who are looking for an interface solution that can support high data rates and have high reliability. The 77428-144LF can provide up to 48 lanes of I/O on a single card edge and supports speeds up to 16Gbps as well as the low/medium speed requirements of various I/O protocols such as USB3.1, several Gigabit Ethernet, SATA/SAS, and LVDS. It also provides excellent EMI protection and 5GHz signal integrity.The 77428-144LF features a two-part design that consists of the connector housing and the contacts. The housing is comprised of two insulating shells with an aluminum shield and a grounding strip. The contacts are made of high-performance materials. They have a high conductivity rating and provide superior electrical performance. The contacts are spaced in a 2.54-mm grid pattern and designed to mate with the headers.The 77428-144LF connector features a contact-retention mechanism that ensures reliable contact engagement and an improved resistance to shock and vibration. It also has a positive latching system for secure connection and easy assembly. The latching system helps to keep the contacts firmly engaged, even in high-vibration environments.The 77428-144LF can be used in a wide range of applications, including industrial control, communications, consumer electronics, networking, storage systems, PCs, automotive, medical, and aerospace. It is also suitable for use in board-level connections, such as embedded systems, and I/O device activities. The connector provides a reliable and cost-effective solution for signal transmission and I/O needs.The working principle of 77428-144LF is simple. The connector is a two-part design with a mating interface. The contact pins of the connector housing are aligned at a 2.54-mm grid pattern with the contact pins of the header. The contact pins of the housing are then inserted into the contact slots of the header. The contact pins are then pressed into the contact slots in the header to form an electrical connection. The contact pins are designed in a manner that provides a secure and reliable connection.In conclusion, the 77428-144LF connector is a reliable and cost-effective solution for board-level I/O and signal transmission needs. It is designed to provide high data rates with EMI protection and 5GHz signal integrity. The connector is suitable for a wide range of applications and its contact-retention mechanism ensures reliable contact engagement. Its working principle is simple and it provides a secure and reliable connection for a variety of applications.
