Product Description

This Mini SAS HD to U.2 NVMe connector cable is designed for linking a backplane or HBA using an SFF-8643 interface to a 2.5" U.2 / SFF-8639 solid-state drive. High-speed twinax wire cable and precision-machined copper terminals provide controlled impedance and low insertion loss, allowing stable transmission of high-frequency differential signals for SAS or PCIe NVMe storage.

The entire assembly is wrapped with a rugged black braided sleeve that protects the electrical cable bundle against abrasion while keeping routing neat inside dense server and workstation chassis. Positive-latch connectors on both ends ensure secure mating with host and drive PCBs even under vibration, making this harness suitable for 24/7 data-center environments. OEM and ODM customization are supported, including special pin-outs, different cable lengths, custom labels, or integration with other power and data connectors in one harness for complex storage modules.

Applications

Connecting U.2 NVMe SSDs to Mini SAS HD ports on RAID/HBA cards or motherboard headers

High-density enterprise server and storage arrays, JBOD and JBOF enclosures

PCIe-based all-flash systems and hybrid SAS/NVMe backplanes on industrial PCB designs

Workstations, edge-computing nodes and telecom equipment requiring compact, reliable storage interconnects

Custom storage appliances and OEM chassis where braided, low-profile cabling improves airflow and cable management

Precautions

Verify that the host port is SFF-8643 and the drive uses a standard U.2 / SFF-8639 interface; do not force the connector into incompatible sockets to avoid bending pins.

Observe the recommended bend radius of the twinax wire cable to maintain impedance control and prevent degradation of high-speed signal transmission.

Ensure the system’s power budget supports the connected U.2 SSD; this harness only routes power rails provided by the host and does not include its own regulation.

Route the assembly away from sharp metal edges and strong EMI sources; secure it with clips or ties so that stress is not transferred to the board-mounted terminals.

Custom harnesses combining multiple Mini SAS HD links, alternative pitch connectors, or additional automotive / industrial grade protections can be supplied for batch projects.
