Mini Cool Edge Connectors & Cable Assemblies

Molex Mini Cool Edge (MCIO) Connectors and Cable Assemblies deliver 4x, 8x, 16x, and 20x options with high-speed 16Gbps, 32Gbps, and up to 64Gbps data rates. These products offer improved flexibility in system designs due to the straight, right-angle, and side-exit options for multiple plug types. Damage to the pins is prevented because of the anti-slant, anti-reverse, and pull-tab features with contact protection and enhanced mechanical design. MCIO connectors and cable assemblies provide the flexibility to pair with different wire gauge options, including 32AWG, 30AWG, and 29AWG. Molex MCIO Connectors and Cable Assemblies are suitable for data centers, storage racks, routers, servers, edge computing, and storage controllers.
