Contact count

Not asserted

PHR-4 crimp cable housing, distinct from its separately selected PCB header

Mating boundary

Shape is not the verdict.

Use the exact manufacturer mating component, terminal/cable and current drawing. Only PHR-4; no family-wide generalization. A source-described lock, key or dimensional resemblance is not an approved equipment connection.

How to read this profile

Textual manufacturer construction/configuration facts and explicitly labelled dimensions only. No mating-face, termination-side, contact-number layout or PCB footprint is reconstructed.

Bounded dimensions

Only what the sources support

Not recorded: Nominal contacts, Populated contacts, Contact gender / arrangement, Keying / polarization, Shell / form, Recorded markings. Unknown fields stay unknown; illustrations supply no measurements or pin assignments.

Unknowns stay unknown.

Housing positions do not establish separately fitted contact population, terminal choice or equipment pin assignments.
Catalog A/B labels are retained without inferring a physical axis, tolerance, mating-face map or PCB footprint.
No numbered electrical contact assignment, hardware test, specimen measurement, fabrication approval or complete application rating/derating is established.
