EDAC offers five subcategories of Card Edges, each with their own unique features and benefits. Understanding what those are will help a designer pick the most efficient solution for their project. Standard Card Edge connectors are the largest offering available and can cover a variety of applications. Press-Fit Card Edge connectors utilize a contact design that allows ease of assembly in a PCB with a simple flat rock tooling. These connectors have powerful shock and vibration resistance when they are installed. Metal-to-Metal Card Edge connectors are EDACs high reliability connector product. The high reliability comes from the Edacon hermaphroditic contacts which are contacts that have a fork like design. This makes the mating surfaces have a gas tight connection, letting nothing get in between the two mating surfaces with high shock and vibration resistance. For board-to-board or wire-to-board applications, they can be used with 0.062” or 0.093” PCBs.
