This 34 Pin IDC Female Connector is used with a Crimped Flat Ribbon Cable(FRC) of pitch 1.27mm.
IDC socket connectors are used to make physical connections in a variety of applications. They are common in industrial applications, where the accuracy of connections, the ability to make them reliable, and where there may be many wires that need to be connected at once are all vital considerations.
This IDC product technology allows cost-effective connections between circuit boards based on a permanent connection (using transition connector) or removable connection (using IDC flat cable connectors).
They are also ideally suited for environments where dust and other hazards may pose significant threats to electronic equipment.
