89177 Series, Edgeboard Connectors

Card edge connectors, also known as edgeboard connectors, are a popular style of connector system widely used in various applications. These connectors utilize a pattern of exposed copper regions located at the edge of a printed circuit board (PCB) to form one half of the mating connector pair. One common application for card edge connectors is the connection of accessory cards, such as graphics accelerators, to computer motherboards in desktop PC applications. The exposed copper regions on the PCB serve as the male contacts of the connector system, while the complementary female contacts are housed within the mating connector. One of the key advantages of card edge connectors is their relatively low cost compared to other connector options. This makes them an attractive choice for applications where cost efficiency is important. Additionally, card edge connectors offer high density interconnect capabilities, allowing for the connection of numerous signals or power lines in a compact space. It's worth noting that card edge connectors may not be the preferred choice for applications where durability is a primary concern. While they provide reliable electrical connections, they may not offer the same level of mechanical strength and protection as more robust connector systems. In summary, card edge connectors are a cost-effective and high-density interconnect option commonly used for connecting accessory cards to motherboards in desktop PC applications. Their design incorporates exposed copper regions on the PCB, which form one half of the mating connector pair. While they may not be suitable for applications requiring exceptional durability, they offer a practical solution for many connectivity needs.
