D-Sub connectors are an important type of electrical connectors designed for applications such as PC interfaces, automotive wiring, and more recently for use in the aerospace industry. The L77DD50SA D-Sub connector is a high performance, high frequency connector designed for generic applications where very low insertion loss and return loss are essential. It exhibits superior electrical performance even when mated with most standards.

Application Field of L77DD50SA:

The L77DD50SA D-Sub connector is a versatile electrical interface connector designed for many applications. It is popular for use in the PC interfaces, automotive wiring, aerospace and military industries. It is widely used in applications such as: signal transmission within PCBs, interconnections between a PC/Server and a network, and in instrumentation systems. It can also be used in telecom facilities wiring and in hi-tech industrial systems. This versatile connector is also a popular choice for many radio frequency and microwave applications.

Working Principle:

The main feature of the L77DD50SA connector is its use of a flat flexible cable (FFC) between two printed circuit boards (PCB). The FFC is used to connect the two PCBs together and provides a low-resistance connection using extremely robust insulation materials. The FFC has two flat layers; one of these layers is made of flexible copper wires that provide the electrical connection between the two printed circuits. The other layer is made of a tough resilient insulator to protect the wires from short circuits and environmental elements. The two copper wires are welded together with a tiny mechanical wire clip which creates a firm electrical connection.

The L77DD50SA connector can operate within a frequency range of up to 300MHz and has a rated contact performance of 75mΩ maximum at 2GHz. This is an impressive performance and suitable for many high-frequency applications. The connector is also UL listed and CSA certified, making it a safe and reliable electrical connector.

This D-Sub connector is a cost-effective, high-performance alternative to other D-Sub connectors which are used in applications requiring superior electrical performance. By combining the versatility of a flat flexible cable and the dependability of the L77DD50SA connector, applications can benefit from a reliable, cost-effective electrical connection.
