The connector is a standard 26-pin “mil-spec” 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 Amphenol, ITT Cannon and other manufacturers. |

The connector is compatible with Güralp Systems' velocity sensors, so you can use the same cables for any type of sensor. It is also compatible with breakout boxes and HCUs for 40T and 5TB instruments.
