D-Sub Connectors

D-Sub connectors (also called D-Subminiature or D-Sub) are generic terms covering a metal shielded 32, 44, or 62 contact connector range designed for reliable data and signal connections. The connector was developed by D Sub Connector Inc. and features a high-density connector with balanced electrical characteristics and a robust mechanical structure. This small, lightweight connector is designed to help minimize the space required in tight applications and provide reliable data and signal connections in harsh environments. The D-Sub connector range includes the following:- L77HDCH62SVFC309 – a version based on a metal shell for extra shielding and protection against electrostatic interference and high-frequency signal loss- HD60 – a version based on a reduced size and comes with a variety of contact configurations- HD84 – a version with metal shell and increased resistance against harsh environmental conditions- HD97 – a version featuring a higher pin density

Application field and Working Principle of L77HDCH62SVFC309

The use of the L77HDCH62SVFC309 connectors in applications has expanded dramatically since its inception, thanks to its high density, robust mechanical structure and balanced electrical characteristics. The L77HDCH62SVFC309 connector is suited for a variety of applications, including Audio/Video, Power, Communications, and Automation and is most often found in industrial and telecommunication systems, such as broadcasting facilities, Ethernet LANs, and signal routing within control panels.The L77HDCH62SVFC309 connector, with its metal shell, is a shielded version of the D-Sub connector range, which offers greater protection against damage due to EMI, RFI, and other external influences. It features lower resistance, reduced noise, and improved power transfer capabilities due to its special contact design. The connector is designed with a secure and robust system, allowing for secure and repeatable mating cycles and increased durability. The L77HDCH62SVFC309 connector employs a unique double-pin contact system, which is designed to increase the strength and stability of the connection. It also helps reduce the effects of EMI and RFI significantly by using a metal shell as the contact point between the pins. This reduces the risk of contact damage due to fatigue, vibration, shock, and electromagnetic pulses. The connector also features a unique screw-lock system to ensure a secure connection. It also helps to reduce labor costs as two technicians are not required to make the connections. The L77HDCH62SVFC309 connector also offers reliable operation in temperatures ranging from -30°C to +85°C and is UL/cUL and EN approved. It is also available in various contact configurations from 32 to 62 contacts.In conclusion, the L77HDCH62SVFC309 is a high-density, reliable and robust connector designed for a wide range of industrial and telecommunication applications. With its metal shield, special contact design and screw-lock system, it offers robust performance and reliable data and signal and power transfer capability even in harsh environments.
