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. |

Pin | Function | Pin | Function |
A | Velocity +ve, vertical channel | P | Calibration signal (all channels) |
B | Velocity –ve, vertical channel | R | Calibration enable, Z channel |
C | Velocity +ve, N/S channel | S | Calibration enable, N/S channel |
D | Velocity –ve, N/S channel | T | Calibration enable, E/W channel |
E | Velocity +ve, E/W channel | U | Centre |
F | Velocity –ve, E/W channel | V | not connected |
G | Mass position, vertical channel | W | Unlock |
H | not connected | X | Lock |
J | Mass position, N/S channel | Y | Logic ground |
K | BUSY LED | Z | not connected |
L | Mass position, E/W channel | a | not connected |
M | Power –ve (optional) | b | Power ground |
N | Signal ground | c | Power +ve |
* Optional lines for sensors with the RS232 control option. The RS232 ground is isolated from pins a and Z using 10 nF decoupling capacitors.

7.2 Breakout box POWER connector
This is a standard 10-pin military-specification bayonet plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-12-10P although the initial “02E” varies with manufacturer. Suitable mating connectors have part-numbers like ***-12-10S and are available from Amphenol, ITT Cannon and other manufacturers. |
