Backplane connectors, which are specialized hardware used in networking equipment, provide a passive interface between the backpanel of the device and the backplane board. A backplane, by providing a common bus that interconnects several components, allows for efficient communication between them. The backplane connector 51939-261 is designed to be used for this purpose. This article will explain the 51939-261 backplane connector’s application field and working principle.

Application Field

The 51939-261 is suitable for use in datacom, telecom and industrial automation applications. It is designed according to IEC 61076-2-101 standards, which are the international standards for most types of backplane connectors. The 51939-261 connector is able to provide multiple levels of isolation to protect the devices from signal interference, and it also ensures that the signals stay clean and stable at high speeds. In addition, it has a reliable latch-locking mechanism to ensure that the connection is secure.

The 51939-261 provides up to 12 positions for pins and 738 pins on a 3U board. This makes it suitable for applications with high pin count requirements as it allows increased device density on the board. It has a minimum pin pitch of 0.40mm and is able to operate at signal speeds up to 5Gbps. The connector also features low electrostatic discharge (ESD) protection to prevent damage to sensitive electronics.

Working Principle

The 51939-261 backplane connector works by connecting a device’s backplane board to the backplane connector on the back of the device. The backplane connector acts as an intermediary between the two components, acting as a bridge between the two components. The connector contains several pins and receptacles, which mechanically and electrically connect the backplane board to the backplane connector.

The 51939-261 connector also integrates shielding to reduce the possibility of interference from other components. The connector contains EMI shielding along with UVand water-resistant sealing to reduce potential damage caused by exposure to liquids. The connector is also equipped with a cover for additional protection against dust and other airborne particles. In addition, the 51939-261 connector is designed to have low contact resistance, which helps ensure reliable connections.

The 51939-261 backplane connector is an ideal choice for applications that require a reliable and secure connection between two components. It is also well-suited for use in applications that require high signal speed and a large number of pins. The connector is able to provide an efficient and reliable connection, making it an ideal choice for datacom, telecom and industrial automation applications.
