Backplane Connectors - DIN 41612

Backplane connectors, also known as DIN 41612 connectors, are broad, low-profile connectors used in data communications and equipment networks. The DIN 41612 series is an international standard for data communications connectors developed by the German Institute for Standardization (DIN). These connectors are used in a variety of equipment including computers, mainframes, servers, telecom equipment, and computer peripheral devices.

Applications

Backplane connectors are used in a variety of applications. They are commonly used in servers, mainframes, and telecom equipment. Backplane connectors are also often used in distributed or Local Area Networks (LANs) and are generally regarded as the standard in this type of applications. A variety of different backplane connectors is available, ranging from simple RJ45 connectors to 4-pin versions suitable for Thin Ethernet and Token Ring networks.

Backplane connectors are also used in the design and manufacture of computer peripheral devices. The most common peripheral devices installed using backplane connectors are keyboard, mouse, monitor, external storage devices, printers, and scanners. Other less common peripheral devices such as security cameras and audio equipment can also be installed using backplane connectors.

Backplane connectors are also used to connect internal electronic components such as memory, central processing unit (CPU), graphics card, storage devices, and sound cards. Such components typically connect to the motherboard directly or via backplane connectors.

Working Principle

Backplane connectors are relatively straightforward devices that can be easily installed on a motherboard. The DIN 41612 series uses a simple cable and connection to transmit signals between the motherboard and other devices. The backplane connector consists of two parts: the base card, which is connected to the motherboard and the backplane module. The backplane module is connected to the base card by a cable, and signals are transmitted through this cable.

DIN 41612 uses a dual row and multi-contact design that supports both differential or single-ended TTL signal transmission. Depending on the type of application, the connector may support a variety of signal types including TTL, RS422, RS485, and other various serial and parallel interfaces. The dual-row design also allows for an enlarged contact spacing for improved reliability in high-vibration applications.

Conclusion

The DIN 41612 series of backplane connectors is a versatile and reliable connection solution for a variety of data communication and equipment network applications. Given their simple installation and support for a variety of signal types, these connectors are ideal for use in distributed and LAN networks as well as for computer peripheral installation. They are also commonly used in the design and manufacture of homebrew computer systems.
