Backplane connectors are typically used for high-speed signal transfer between PCB boards and systems. Backplane connectors categorize into different classes according to their applications. Specialized backplane connectors, such as HDC-R140-41P2-KV, are designed to support specific applications and used in systems or circuits where consistent signal strength and accurate transmission are necessary. This article will explain the application field and working principle of HDC-R140-41P2-KV as a showcase of specialized backplane connectors.

HDC-R140-41P2-KV is a high-density connected device specially designed for server, storage, and communication applications. The connector has 146 contacts for signal transmission and is highly suitable for high-speed signals and/or densely-packed signal paths. The device is composed of two parallel rows of 74 contact pins, where the two sides of each row are connected, hence the ”KV” part in the name. The number of contacts helps minimize the wiring, i.e., reducing the number of cables thus saving space for chip-level integration.

The connector’s contact spacing is just 1mm, the contact length is 5mm, and the pin header and plug terminals are made of Phosphor bronze alloys with gold-plating or tin-plating contacts. This design makes the connector sturdier, allowing it to have a greater operating temperature range between -40℃ and +120℃, while also boasting excellent electrical characteristics while maintaining high reliability.

The working principle of HDC-R140-41P2-KV is relatively simple. When two-way connections are needed, the mating of the board-to-board connection is limited, and the connector is nicely tucked between two PCBs. Once the connection is completed, signals pass through the two parallel rows of pins, where each row contains 75 pins with a pitch of 1mm or 4-position terminal blocks at 1.27mm pitch. The signal transfer efficiency is maximized due to the short wiring path.

HDC-R140-41P2-KV is an excellent specialized backplane connector designed for high-speed signal transmission and space-saving application. By using the small size of the connector and the tight contact spacing, the device can be used with the highest signal integrity to support high-speed communication between boards or systems. It is thus highly suitable for many high-end applications, such as high-density server and storage systems, as well as data communication networks.

HDC-R140-41P2-KV is an example of specialized backplane connectors which have specific application fields and working principles. The specific design of this connector allows users to balance system size and signal integrity, thus making it a popular solution for server, storage and communications fields. All its features make it a reliable, quick and robust connector that will help manufacturers create a compact and reliable signal transfer environment.
