Chapter 7. Appendix A – Connector pin-outs
7.1 Fortis instrument connector
This is a standard 26-pin military specification bayonet plug, conforming to MIL‑DTL‑26482 (formerly MIL‑C‑26482). A typical part-number is 02E‑16‑26P although the initial “02E” varies with manufacturer. Suitable mating connectors have part-numbers like ***‑16‑26S and are available from Güralp Systems or directly from Amphenol, ITT Cannon and other manufacturers. |
