Unknown fields stay unknown; illustrations supply no measurements or pin assignments.

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.
Prior view context (not a source-view value): Position count is published without a V40 mating-face numbering locator.
