Backplane connectors are used to connect multiple circuit boards with a fixed physical connection within a system. Many modern electronic products utilize backplane connectors, such as computer networks, industrial machinery, and telecommunications systems.

One type of backplane connector is the 0746 series, also known as the 10-contact connector. This connector is ideal for applications in which two adjacent boards need to remain electrically isolated. With the 0746 series\' robust construction, these connectors are reliable and lasting.

Application Field

The 0746 series is widely-used in the industrial and telecommunications industries. It has been implemented in many combination components such as switchboards, synchronizing pulse receivers, and splitters. In addition to its core application of connecting two boards, the 0746 is now used for interconnecting telecommunications cables in optical link systems and for connecting signal lines between carrier devices.

Working Principle

These connectors utilize a standard 10-pin design, with two rows of five pins. The pins are spring-loaded, which allows for secure, rigid connections, and ensures a reliable electrical connection between boards. The pins\' retention force is tested and adjusted to meet an industry standard of 180N. This provides assurance that the pins will remain in their connections for as long as they are needed.

The 0746\'s receptacles provide 360°screening, which isolates each pin independently. This helps shield against electromagnetic interference (EMI) and is essential for applications in which electrical sources are present. With an insulation resistance of 1000MΩmin. and a dielectric strength of 1500VAC/min., the 0746 series can withstand up to 4000 mating cycles, ensuring quality performance over a long period of time.

The 0746 connector utilizes open vent design which eliminates the need for the use of a breather port when using in pressurized environments. This allows for higher packing density and greater convenience in tight spaces. The 0746 series is also capable of working in temperatures ranging from -30°C to 90°C, making it an ideal choice for both extreme temperature applications and standard environments.

The 0746 series makes connecting two boards fast, easy, and reliable. Its sturdy construction and 10-pin design make for a secure connection. Additionally, its open vent design and 360° shielding provides added protection from EMI. The 0746 series is an excellent choice for applications in which permanent, secure connections between two boards are required.
