It is designed and tested for maximum electrical performance in signal, power and ground applications. Its purpose is to provide low insertion force, high stability and cushioning in high vibration applications.
Application FieldARINC 1218814-1 backplane connector is designed for high-speed data transmission and signal routing, allowing for the easy connection of components on printed circuit boards. It is suitable for applications in the telecommunications, information technology, avionics, and automotive industries. It is also ideal for use in data logging and data acquisition applications, as well as in instrumentation and control systems. Additionally, ARINC 1218814-1 is suitable for applications requiring power, such as those utilizing renewable energy sources or in power systems that require very high current levels.
Working PrincipleThe ARINC 1218814-1 backplane connector is designed for efficient and reliable operation. The basic principle relies on its ability to create an electrical connection between two printed circuit board components. The connector is composed of two rows of pins arranged in a matrix, where one row is plugged into one component and the other row into the other. It is electrically contacted through a blade-like contact, and when the connector is aligned, the two rows of pins engage with each other and establish a solid electrical connection. The contact is compliant and designed to cushion against shock and vibration, eliminating overall system failure.
This connector utilizes two types of pins in order to ensure fast, reliable and secure contacts. The first type has a square face and is used when connecting power signals, while the second type has an oval face and is used for data signals. The pins feature a special corrosion-resistant finish that allows for better contact and low contact resistance. Additionally, the two-piece design of the connector offers improved shock and vibration performance, as well as improved sealing for IP68/69k dust, water and oil ingress protection ratings.
The ARINC 1218814-1 backplane connector also features a high-speed data transmission capability with speeds up to 12.28 Gb/s (12.288 Gb/s). The electrical characteristics are optimized for high-speed, high-frequency signals with excellent grounding and power distribution. It also utilizes advanced technologies such as impedance-controlled routing, multiple shielding areas, zero insertion force and quick-disconnect locks. Additionally, the ARINC 1218814-1 offers enhanced signal integrity, significantly reducing the risk of electrical noise and crosstalk.
Finally, the ARINC 1218814-1 has been designed to meet the stringent performance requirements of various technologies, including Ethernet, Fibre Channel and Serial Attached SCSI (SAS). It is also compatible with ARINC 615, 616-5, 617-7, 618-2 and 619-4. This ensures that the connector is able to provide superior performance in a variety of applications and environments, while also offering superior connector life and reliability.ConclusionThe ARINC 1218814-1 backplane connector is designed for superior performance in a wide range of applications. The connector is composed of two rows of pins that come in two contact types, and feature a special corrosion-resistant finish to ensure fast, reliable and secure contacts. Its small form factor modular design allows for high-speed data transmission with speeds up to 12.288 Gb/s, as well as improved shock and vibration performance and improved sealing for IP68/69k dust, water, and oil ingress protection ratings. Additionally, it meets a variety of performance requirements, ensuring superior connector life and reliability. Overall, the ARINC 1218814-1 backplane connector provides an excellent solution for efficient and reliable electrical connection in a variety of conditions.
