7964-6500EC – 3M

The 3M 7964-6500EC is a 64-position Insulation Displacement Connector (IDC) receptacle designed for terminating flat ribbon cable. It accepts 26 to 28 AWG stranded or solid conductors with a conductor spacing of 0.050 inches (1.27mm). The connector body is constructed of a UL 94V-0 rated thermoplastic material, providing flame retardancy. Electrical connection is achieved via gold-plated beryllium copper contacts, ensuring reliable signal transmission and corrosion resistance. The gold plating thickness is typically specified to meet industry standards for durability and low contact resistance. Polarization features are incorporated to prevent mis-mating. The connector is designed for mass termination, allowing for simultaneous connection of all 64 conductors, reducing assembly time and ensuring consistent termination quality. It is commonly used in applications requiring high-density interconnects, such as data acquisition systems, telecommunications equipment, and industrial control systems.
