The 3M 7700 Series Round Conductor Flat Cable is a specialized cable designed for applications demanding controlled impedance and reliable signal transmission. Constructed with 30 AWG solid, tin-plated copper conductors, the cable is insulated with polyolefin and features a unique covering of aluminum and polyester, providing a metallic appearance. The controlled impedance ensures minimal signal distortion, making it suitable for data communication and other critical applications. The cable's construction includes a thin conductive layer at each edge, and users should evaluate its use in their application, potentially applying insulating tape as needed. It is designed to meet stringent performance requirements and is widely used in various industrial and commercial settings.
