4) Pin / terminal information extracted from the datasheet
The datasheet clearly states:
  • Contact form is SPDT (1c)
  • Coil has no polarity
  • The package variant uses an 8-hole pattern
What is not cleanly recoverable from text extraction alone is a fully trustworthy per-pin functional map for all 1...8 pin numbers. The terminal diagram is present in the PDF, but the extracted text for exact pin-role mapping was inconsistent across passes. Because of that, I cannot certify the current numbered terminal mapping from text extraction alone.

Flagged issues High-risk issue
  • The current symbol’s functional terminal naming and numbering cannot be confirmed against the datasheet’s terminal arrangement with enough confidence from the extracted PDF text.
  • If even one of COIL_1, COIL_2, COM_1, COM_2, N.O._1, N.O._2, N.C._1, or N.C._2 is assigned to the wrong pin number, that can cause:
    • wrong PCB wiring
    • incorrect relay behavior
    • possible board failure in use
Medium-risk issues
  • All symbol pins are typed as Unspecified rather than coil/contact-related electrical types.
  • The footprint appears present and the pad count matches, but I could not retrieve enough layout geometry to prove the exact hole positions and pitch match the datasheet.
  • Using eight independent terminal symbols instead of a relay symbol makes review harder and increases the chance of pin-mapping mistakes.
Bottom line
  • The metadata is mostly consistent with the datasheet.
  • The biggest unresolved manufacturing/function risk is the exact pin-number mapping between the schematic symbol and the datasheet terminal diagram.
  • The footprint likely has the correct 8-pin through-hole pattern, but exact geometry could not be fully confirmed from the available layout data.
If you want, I can next help you turn this into a precise correction checklist for the part so the symbol and footprint can be verified pin-by-pin against the datasheet figure.
