Backplane connectors are specialized connectors used to ensure signal integrity in backplane-based communications systems. The 1892820-1 is a specific example of a backplane connector that represents an important advancement in the field. This article looks at the specific application field for the 1892820-1 and explains the basic working principle upon which it operates.

Application Field

The 1892820-1, a compact 2mm spacing plug-in card connector family, is perfect for applications that require a small form factor. Its two types, provided either for straight-through or right-angle plug-in cards, enable it to be used in small equipment, such as mobile phones, laptop computers, digital cameras, and other portable devices. Additionally, the 1892820-1 is particularly suited for applications in the field of precision instruments, such as those used in medical equipment, laboratory instruments, security systems, and industrial controllers.

Working Principle

The 1892820-1 is a signal-level backplane connector. It delivers superior electrical performance and signal integrity at a frequency of up to 12 GHz. It is a robust connector capable of ensuring signal integrity up to 6.5 Gbps in a single connector. Furthermore, as its contacts are precision-manufactured using a patented process, they provide enhanced line contact to the pads of the PCB, enabling greater signal integrity and higher reliability. The 1892820-1 relies upon micro RF contacts, for the transmission of high-frequency signals, along with ultra-fine contact tails for low-frequency signals.
