Chapter 7. Connector pinouts

7.1 Sensor and control unit pin output

Models with a 26-pin bayonet plug have the pin assignments below. The RECORDER and HCU connectors on the breakout box are connected directly to the SENSOR connector, and behave identically.

This is a standard 26-pin military-specification 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.
