1. Purpose
This document captures the technical details that could be recovered from the marketplace listing for the purchased plugboard jack sockets used by Enigma-NG. It is not a manufacturer-issued datasheet and must be treated as a project-side reference only.
Use this part only where a marketplace-sourced plugboard jack is acceptable and where no stable catalogue MPN or formal manufacturer datasheet has been established.
2. Intended Enigma-NG Use
- Assembly:
design/Mechanical/Plugboard_Assembly/Design_Spec.md - Board interface:
design/Electronics/Encoder/Design_Spec.md - Function: Plugboard / Stecker panel jack socket
- System quantity: 64 sockets total
- Electrical use in Enigma-NG: three-terminal switched mono jack
- Tip:
BT1-BT64decode-half signal path - Switch (N/C): same node as Tip; shorts Switch to Sleeve when no plug is inserted
- Sleeve:
BT65-BT128encode-half input path
- Tip:

4. Enigma-NG Integration Notes
| Attribute | Enigma-NG usage note |
|---|---|
| Jack type | Treat as a switched mono 6.35 mm panel jack |
| Wiring | Harness back to Encoder blade terminals BT1-BT128 |
| Normal state | N/C switch contact provides identity passthrough when no Stecker plug is inserted |
| Plugboard role | Forms the physical plugboard matrix interface for Decode Half to Encode Half bridging |
| Procurement | Purchased marketplace part; no stable manufacturer MPN currently recorded |
5. Known Unknowns / Unverified Parameters
The listing did not provide a trustworthy manufacturer datasheet for these items:
- Panel cutout diameter
- Thread / bushing dimensions
- Exact terminal numbering and pinout drawing
- Contact voltage / current rating
- Contact material and plating
- Insulation resistance / dielectric withstand
- Mechanical life / insertion cycle rating
- Operating temperature range
- Exact manufacturer name and part number
- Compliance data (RoHS, REACH, UL, etc.)
- Dimensional tolerances
These values remain unverified and should not be invented elsewhere in the design docs.
6. Procurement and Risk Notes
- This is a single-source marketplace part rather than a catalogue component with a stable MPN.
- The listing identifies the item only as Unbranded, so long-term repeatability is uncertain.
- Extra spares should be retained because the exact physical variant may drift over time.
- If the plugboard hardware is ever redesigned for long-term maintainability, this part should be replaced with a catalogue switched mono jack that has a formal manufacturer datasheet.
7. Document Status
This pseudo datasheet is sufficient to preserve the currently known connector style and marketplace listing metadata for the purchased Enigma-NG plugboard jack sockets. It does not replace a real manufacturer datasheet.
