3M™ Low Profile I/O Twin Axial Cable Assemblies is a family of cable assemblies including; x4 38p, x8 74p, x16 124p connectors utilizing 3M™ Twin Axial Cable 85 ohm, 31 AWG and 30 AWG which is ideal for PCIe® applications.

3M™ Low Profile I/O Twin Axial Cable Assemblies are designed to support high density PCIe® applications and are compatible with most Amphenol® SlimSAS™ Low Profile board mount connectors. The thin, low profile 3M Twin Axial cable allows for a wider range of routing options and supports extremely tight bend radii for unique server configurations. S-parameter performance metrics are not degraded, even with multiple folds.
