Product Description

This Mini SAS HD SFF-8643 to SFF-8643 connector cable is engineered for reliable high-speed data transmission inside enterprise servers and storage systems. Both ends use 36-pin Mini SAS HD connectors with secure metal latches, ensuring a stable mating interface between RAID controller, HBA card or backplane PCB.

The 30AWG copper twinax wire cable with individual and overall braid shielding maintains controlled impedance and low crosstalk for 6G/12G SAS digital signals, delivering consistent performance in high-density electronic environments. A durable black braided outer sleeve protects the internal power reference and signal pairs from abrasion, while keeping the harness flexible and easy to route in narrow chassis.

This assembly supports OEM/ODM customization such as different lengths, routing style, right-angle or straight plug options, additional grounding pins, as well as integration into complex multi-drop storage harnesses. It is ideal for system integrators who require stable, low-loss Mini SAS HD connector solutions for modern storage platforms.

Applications

Internal high-speed links between RAID/HBA cards and SAS backplanes in rack-mount servers and data-center storage arrays

JBOD/JBOF enclosures, NAS appliances and enterprise disk shelves requiring reliable Mini SAS HD connectors

High-performance workstation and GPU server builds where compact, well-shielded cable routing is necessary

Industrial control systems and embedded computing platforms using SAS or PCIe-based storage modules on custom PCB designs

OEM storage subsystems that need robust Mini SAS HD connector harnesses for mass-production assemblies

Precautions

Confirm that the host and device ports are both Mini SAS HD SFF-8643 and that the pin assignment matches the target system layout before installation; incorrect mating can damage terminals or host boards.

Avoid exceeding the recommended bend radius of the braided wire cable and do not sharply twist the harness near the over-molded ends to protect the internal signal pairs and power reference conductors.

Route the cable away from sharp edges, high-current power lines and strong EMI sources whenever possible to maintain signal integrity.

For long-term operation in harsh server or automotive environments, project customers can request enhanced insulation, wider pitch or special jackets to match specific temperature and vibration requirements.
