Backplane connectors are a special type of connector used to join two or more printed circuit boards (PCBs). The most common type of backplane connector is the 75705-5103, which is used to connect standardized backplane bus structures. It has a simple construction, but is capable of providing up to 250 distinct contact points.

The 75705-5103 backplane connector is designed for high-speed data transfer and signal integrity. It uses an ultra-low profile contact system that is relatively low-cost and easy to assemble, while providing outstanding reliability and performance. The connector employs a dual-row contact system with open-ended, snag-free socket contacts, which provides improved signal integrity in high-reliability applications.

The 75705-5103 connectors employ board-to-board contact technology that is designed for the highest signal integrity. There are two series of connectors (Light Duty Series and Heavy Duty Series) to meet different application requirements. The Light Duty series supports up to four layers and is suitable for a variety of backplane bus structures, while the Heavy Duty series can be used for multiple board layers with increased contact density and highly reliable signal transmission.

The 75705-5103 backplane connectors consist of a die-cast aluminum shell that is machined to a precise detail, providing a secure, durable connection. The connector is equipped with a conductive metal-alloy gasket and integrated mounting hardware for improved stiffness and a secure fit. The shell also features an ergonomic design that minimizes application complexity and facilitates easier assembly.

The 75705-5103 connector’s working principle is based on two integral parts, the contact and the shell. The contact is composed of precision die-cast metal arms that snap into the shell and provide a dependable connection between the two boards. The contact is also designed with a conductive metal-alloy gasket that eliminates the need for additional components and provides a reliable electrical connection. The shell is composed of anodized aluminum and is designed with a precise clearance to provide a secure and reliable fit.

The 75705-5103 backplane connector is a reliable, cost effective solution for a variety of applications. It meets the demands of high-speed data transfer and signal integrity and is suitable for a variety of backplane bus structures. The connector is resistant to harsh environmental conditions, provides a secure and reliable connection, and is easy to assemble. Thanks to its simple construction and low-cost design, the 75705-5103 backplane connector is a convenient, reliable, and cost-effective choice for a variety of design applications.
