Recorded variant and source limits

This assignment does not prove that an arbitrary M8 D-coded port or cable supports a particular Ethernet speed or device role.
No fabrication dimensions, cable category verification or installed-link performance is established.
Phoenix Contact M8 D-coded PROFINET: Phoenix catalog p.44 separate male/female PROFINET D-coded drawings. Key notch up: female has 1 upper left,2 upper right,3 lower right,4 lower left; male is mirrored as drawn. No termination-side convention inferred.
Phoenix Contact M8 4-position D-coded PROFINET assignment: Numbered contacts of Phoenix Contact 4-position D-coded PROFINET interface. Female and male figures are distinct on p. 44; no spatial side assumed.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

Dark pinout view

What the status labels mean

Confirmed: Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source: Only one underlying document, or one pass, supports this assignment.
Device-specific: Supported for the named equipment or wiring only. Check your device’s manual.
Unverified: Missing or conflicting evidence. Do not wire from this row.
Not connected: The source explicitly says NC, no contact or no pin for this wiring.
