STORAGE / CABLE END AND BOARD CONNECTOR

Know the end.
Know what it belongs to.

An external eSATA cable and an internal Mini-SAS board connector carry different evidence. Read the named product, component role and mounting details before making a system-level assumption.

01 / COMPONENT IDENTITY

A cable end is not a board connector.

External cable end

ESATA3: a cable with two eSATA ends.

OBLIQUE PHOTOGRAPH STUDY
eSATA / external cable end. Oblique shield envelope and molded cable body. Seven-pin identity comes from the source table. Individual contacts and hidden key geometry are not plotted. Original qualitative source study; no pinout.

Cable end, not a board receptacle · View, source and omissions (private workspace)

The source identifies both ends as seven-pin eSATA. The qualitative study follows one visible oblique cable end; it is not a receptacle face or pin-number map. The advertised rate belongs to this cable’s documentation, not every similar connector or a measured storage system.

Named cable assembly; no power-delivery claim.

Read the source evidence and scope
  1. StarTech ESATA3 specifies seven-pin eSATA connectors at both ends. C118A

    Identification and explicitly scoped documentation only; not an end-to-end connection approval

    S094 · StarTech.com ↗

  2. The product is an external SATA storage data cable. C118B

    Identification and explicitly scoped documentation only; not an end-to-end connection approval

    S094 · StarTech.com ↗

  3. The ESATA3 datasheet advertises a transfer rate up to 6 Gbps for this named external eSATA cable. C118C

    Manufacturer cable-assembly claim only, not measured system throughput or the capability of every seven-pin connector. No device power or powered-eSATA capability is established.

Internal board receptacle

G40MR: a board connector with a separate cage.

The product page identifies a stainless right-key variant. The family drawing distinguishes SMT contact termination from DIP cage mounting. It does not establish the exact full-suffix keyed face well enough for a new illustration in this release; that visual gap stays open.

Family drawing and named product kept separate; exact face study deferred.

Read the source evidence and scope
  1. Amphenol product G40MR36B22BCEU identifies a 36-contact Mini-SAS internal connector compliant with SFF-8087. C236B

    V40 engineering-reference fact only; independent human review remains pending. This claim does not approve fabrication, rewiring, substitution, electrical safety, protocol support or end-to-end compatibility.

    S257 · Amphenol Communications Solutions ↗

  2. Amphenol describes G40MR36B22BCEU as an internal right-angle board connector with a stainless right-key shell; its product description specifies a DIP cage and cap. C236C

    Exact product-page role and variant descriptors. Not a cable-end connector, a generic Mini-SAS substitution or an independently inspected keyed face.

    S257 · Amphenol Communications Solutions ↗

  3. The G40MR C2 family drawing table distinguishes SMT connector contacts from DIP cage mounting and separately lists keying options. C236D

    Sheets 1–2 of the 2015-04-09 family drawing. The DIP cage does not make every electrical contact a through-hole pin. Exact full-suffix face geometry and current revision remain unverified.

Contact count, a family name or an advertised cable rate does not prove host support, device power, PCB fit or an approved replacement. No trial fitting, soldering or pin-assignment instructions are supplied.

02 / FIND THE NEXT DOCUMENT

Keep the part and the system separate.

Identify an external cable

Confirm both end designations in the cable’s documentation and the required host/device interfaces. Keep the data-rate claim with the named assembly.

Identify an internal component

Record the exact part suffix, keying and mounting role. Read electrical contact termination separately from cage attachment.

03 / COMMON QUESTIONS

What appearance cannot establish.

Does seven-pin eSATA guarantee 6 Gbps?

No. The source’s up-to-6-Gbps statement belongs to ESATA3. The connector count does not establish the host, device or actual transfer rate. Read the equipment and cable documentation together.

Does a DIP cage mean the contacts are through-hole?

Not in the observed table: it lists SMT connector contacts separately from DIP cage mounting. Keep electrical termination and mechanical mounting distinct. No PCB footprint or soldering instruction is supplied here.

Why is there no new Mini-SAS face illustration?

The exact product page names a stainless right-key shell, but the linked drawings cover several key and mounting variants. The exact full-suffix face has not been sufficiently resolved. A generic family picture would overstate that evidence.

A COMPACT REFERENCE TO KEEP

Cord ends and storage component roles.

Letter PDF (legacy download held for current evidence review). Current focused printable references · A4 PDF (legacy download held for current evidence review). Current focused printable references

Four pages: NEMA examples, storage roles, next questions and linked source records. Original review-edition PDF; no electrical work or mating approval.

The source limits stay visible.

The ESATA3 PDF is undated; its unusual environmental and weight fields are not promoted. The G40MR drawing is revision C2, dated 9 April 2015, not certified as the current revision. Its generic family views do not resolve the exact full-suffix keyed face sufficiently for a new illustration.

Sources were observed on 14 October 2026. New illustrations use original geometric primitives, not copied manufacturer photographs or drawings. No inspected hardware, exact dimensions, assigned pinouts, independent technical approval or artwork-rights approval is claimed.
