M.2 NVMe Male Turn 180 Degree to PCIe 4.0 x4 Female Extension Cable, 85-ohm Low Impedance

The M.2 NVMe Male Turn 180 Degree to PCIe 4.0 x4 Female Extension Cable is a specialized interface conversion solution engineered to connect M.2 NVMe slots to standard PCIe 4.0 x4 interfaces with a unique 180-degree rotation and precision 85-ohm impedance control. This cable enables the use of M.2 NVMe storage and other M.2 PCIe devices with motherboard PCIe x4 slots, providing flexible expansion capabilities and spatial reorientation for systems where direct M.2 slot availability is limited or where specific 180-degree cable routing is required for space-optimized configurations. Supporting PCIe 4.0 specifications, it delivers a data transfer rate of up to 16 GT/s per lane while maintaining backward compatibility with PCIe 3.0 and 2.0 devices. The 180-degree turn design reorients the connection plane, optimizing space utilization and improving clearance in complex chassis layouts and custom mounting scenarios. Constructed with 85-ohm impedance-controlled wiring and multi-layer shielding, this cable ensures reliable signal integrity and minimizes electromagnetic interference at high frequencies. Its flexible flat cable design allows for easy routing in space-constrained environments, making it ideal for custom builds, embedded systems, and expansion projects where traditional adapter cards cannot be used and 180-degree cable orientation is essential for optimal chassis layout.
