L77SDE09SOL2GC309 Connectors, Interconnects

D-Sub Connectors

D-subminiature ("D-sub" or "Sub-D") connectors are a type of electrical connector used for computer and digital equipment. The "D" stands for the shape of the connector, which is usually rectangular with two side-by-side rows of pins and sockets as viewed from the rear of the plug. D-sub connectors are most often found on PC peripherals such as printers, external hard drives, media cards, mice, and keyboards.

The L77SDE09SOL2GC309 is one such D-sub connector. This standard D-subminiature board-mount connector is encased in a 15-pin stainless steel metallic shell and is rated for 5A of current. This connector is RoHS-compliant, making it a popular option for many electronic designs. It is available in both vertical and right-angle configurations.

Application Field & Working Principle

The L77SDE09SOL2GC309 is most commonly used in industrial applications, public transportation, and medical devices. This D-sub connector is designed to accommodate signals, data lines, and power supplies in minimal space. Its robust design makes it an ideal option for applications that require an economical but reliable solution.

The L77SDE09SOL2GC309 connector uses a simple spring-loaded pin-socket connection, the most common mechanism used in most D-sub connectors. When the connector is mated, the sockets on the plug housing latch onto the pins and the spring forces them into contact with the contactor. This creates a secure electrical connection that is maintained even when the plug is disconnected. To ensure a successful, reliable connection, the L77SDE09SOL2GC309 is designed with a high-precision, burr-free internal wall and engineered for precision mating.

Conclusion

The L77SDE09SOL2GC309 is an industry-standard D-sub connector for industrial, transportation, and medical applications. It is a cost-effective solution that provides consistent and reliable connections even in harsh environments. Its versatile design makes it an ideal option for designs that require a dependable but economical connector.
