Mini-SAS HD external SFF-8644 connector engineering reference

Amphenol Mini-SAS HD cable-family reference identifies the external SFF-8644 interface as 36-pin. Exact exampleTE2149027-1 is the1x1 receptacle assembly in the brochure p.6 external Mini-SAS HD family;1x1 describes ports. That external section specifies an LCP receptacle housing, nickel-silver shield, copper-alloy contacts and a preassembled one-piece PCB interconnect. It describes a cable latch and EMI skirt and publishes250-cycle durability for this external connector family. Internal SFF-8643 properties are excluded; this is source documentation, not hardware certification.

Recorded variant and source limits

Position/contact count and any example-component pitch do not establish a universal pinout, cable construction or protocol capability.
No fabrication dimensions or face-view pin locator is published unless explicitly stated.

The2149027-1 example remains separate from internal P238/SFF-8643. Its1x1 value is a port matrix, not contact rows. The separate product page pitch.03mm[.75in] is inconsistent and remains withheld; no external pitch is borrowed from the internal section. Published family durability is not hardware validation.
