HD MINI SAS SFF-8643 72P to 2SFF-8643 HD SFF 8643 Cable for Server Use

Description
The SFF-8643 8i is a 72-pin high-density Mini SAS connector with a plastic body interface typically used for internal connections, primarily used to implement HD SAS internal interconnect solutions. Typical applications are internal SAS links between SAS HBAs and SAS drive subsystems. The SFF-8643 is compliant with the SAS 3.0 specification and supports 12Gbps data transfer protocol.
Oikwan can provide all configurations of the 12Gbps HD Mini SAS and 6Gbps Mini SAS products, we have straight, right angle, left exit and right exit configurations, 4X and 8X connectors are available, the cable types are from twinax cables, fine film laminated cables for loose cables, and the range of conductor sizes is from 32AWG to 28AWG. All of the above products comply with SFF-8643, ROHS2.0, HF, UL approvals and flammability ratings.
