What is Edge Connector

An edge connector is located on the edge of the board and is designed to be plugged into a matching socket on a device or computer to establish a reliable and efficient electrical connection between the PCB and other components.

Edge connectors typically consist of broad metallic tracks that provide the electrical connection. They are known for their ability to provide a fast and secure connection. The connectors are often designed to be keyed for polarity, ensuring that they are properly aligned and connected.

Edge connectors require mechanical force to be inserted into their sockets. However, there are also alternatives available that utilize zero insertion force, allowing for easier insertion without applying mechanical force.

Edge connectors are cost-effective, as they only require a single female connector, with the male connector formed out of the edge of the PCB itself. They are also simple, robust, and durable, contributing to their reliability. Edge connectors can be considered a direct extension of the PCB, allowing for easy connection and disconnection.

There are also some drawbacks. Direct access to the PCB may not always be desirable due to concerns about potential damage or the need for additional protection. Additionally, the contact life of edge connectors is generally shorter compared to other alternatives, which may require more frequent replacement.
