208976-8

ARINC (Aeronautical Radio, Inc.) backplane connectors are used in a wide range of aviation applications. Commonly used in avionics, ARINC connectors are designed for high temperature, vibration resilience, and secure mating. Though there are a wide variety of ARINC connectors available, the 208976-8 is one of the most popular and commonly used.

The 208976-8 is a multi-contact, modularly operated backplane connector that utilises two rows of terminal pins for connection to a printed circuit board. It is typically used for direct board to board connection and is often considered to be the most secure type of ARINC backplane connector. The 208976-8 consists of an inner connector and an outer shell which encloses the inner connector. This shell helps to protect the inner connector and is designed to prevent electrical arcing and other transient electrical conditions. The connector is also designed with a keyed feature to ensure correct insertion.

The 208976-8 backplane connector can be used for a variety of application fields such as data transmission, avionics, telecommunications, and industrial automation. In avionics applications, the 208976-8 is commonly used in flight control systems, navigation systems, and air data computers. It is also used for interconnecting satellite communication systems, satellite navigation systems, and aircraft communications systems. In industrial automation, the 208976-8 is used for data and signal transmission in machinery, process control systems, and other automated equipment. In telecommunications, the 208976-8 is used for connecting components such as computer and telecommunication systems, switching systems, and multiplexers.

The working principle of the 208976-8 is relatively straightforward. Upon connection, electrical contact is made via the two rows of pins in the inner connector. The pins are spring-loaded and when inserted into the outer connector, will create a secure and robust connection with a minimum of two points of contact. This ensures low contact resistance and low insertion force, enabling the transmission of data and signals without disruption. The connector also boasts an insulation resistance of 10,000 Megaohms, making it highly reliable and capable of delivering continuous operation.

In summary, the 208976-8 backplane connectors are designed to provide long-term reliable connections in a wide range of aviation applications. They boast a high temperature, vibration resilience, and secure mating capability, making them ideal for use in mission-critical applications where reliability is paramount. The connector is easy to install and maintain with its two rows of spring-loaded pins, insulation resistance of 10,000 Megaohms, and keyed feature for correct insertion.
