Recorded variant and source limits
  • No IDE/ATA or other protocol pin map is inferred from the 40-position header form.
  • Product dimensions, latch features and pitch do not constitute a fabrication drawing or device compatibility result.
  • Center mating alignment without an identified key/polarizing feature remains context rather than target-qualified keying. Recorded source context: Center mating alignment; ejection latches / 1-1761685-3

Unknowns stay unknown.

  • No IDE/ATA or other protocol pin map is inferred from the 40-position header form.
  • Product dimensions, latch features and pitch do not constitute a fabrication drawing or device compatibility result.
