This is a standard 26-pin “mil-spec” plug, conforming to MIL‑DTL‑26482 (formerly MIL‑C‑26482). A typical part-number is ***‑16‑26P where the '***' is defined by the manufacturer. Suitable mating connectors have part-numbers like ***‑16‑26S. The 26‑pin connectors on the breakout box have identical pin functions. |

*spec refers to the quoted frequency response value, e.g., for a “30 s” sensor, the value of spec would be 30 s = 0.033 Hz.
**Temperatures below –20 °C may be accommodated with additional care. Please consult Güralp Systems for advice.
†Because centring, locking, and unlocking consume varying amounts of power, it is recommended that you use a power supply capable of delivering 1 A at 12 V.
