ARINC Backplane Connectors – BKAD3-271C-40056 Application Field and Working Principle Backplane connectors are electronic connector devices used for backplane data transmission systems. Backplane connectors offer consistent performance and reliable signal integrity while providing a comprehensive range of signal transmission solutions. ARINC backplane connectors comply with the ARINC 600, ARINC 404, and ARINC 429 standards and are typically used for automotive and military applications. The BKAD3-271C-40056 is an ARINC backplane connector that is designed for sealed operations, excellent EMI/EMC protection, and excellent connection reliability.Applications The BKAD3-271C-40056 backplane connector is designed for applications that require a data transmission rate of up to 12 Gbps. It is suitable for a variety of applications, including, but not limited to, automotive, space, ground, and naval systems, industrial automation, communications systems, avionics systems, and instrumentation. Additionally, this type of backplane connector has a standard temperature range of -55°C to +125°C and can be used for sealed operations with a UL 94V-0 rating. Working Principle This type of backplane connector is a differential signal connector with a high noise immunity and impedance stability. It features an exceptionally low Nominal Impedance of 50 Ω, ensuring excellent signal quality and transmission. The BKAD3-271C-40056 connector is composed of an insert, body, and a contact system. The contact system consists of two male (terminal) and female (socket) contact pins located in the middle of the insert. The two contact pins are connected using differential pairs and form a transmission line intended for digital signal transmission. The BKAD3-271C-40056 backplane connector features a floating ground and a unique shielding system. The floating ground allows the two contact pins to move freely when the connector is inserted into a backplane allowing for proper mating. The shielding system consists of two ground brushes that are designed to create an even more reliable connection and to provide additional EMI/EMC protection. The two ground brushes make direct contact with the ground plane of the backplane, providing a reliable ground for the transmission line when the connector is inserted. The BKAD3-271C-40056 backplane connector uses two locking mechanisms to ensure reliable and secure connection. The first locking mechanism is an ejector mechanism which prevents the connector from being accidentally removed when it is inserted. The second locking mechanism consists of a ground spring which applies a tension force to ensure that the contact pins are correctly mating with the backplane contacts. ConclusionThe BKAD3-271C-40056 is an ARINC backplane connector from which is designed for a wide range of applications. This type of connector features excellent EMI/EMC protection and a reliable connection. Additionally, this connector is designed with two locking mechanisms which allow for reliable and secure connection.
