Models with a 26-pin mil-spec plug (02E-16-26P) have the following pin assignments. The RECORDER and HCU connectors on the breakout box are connected directly to the SENSOR connector, and therefore behave identically.
Pin | Function |
A | Velocity +ve, vertical channel |
B | Velocity –ve, vertical channel |
C | Velocity +ve, N/S channel |
D | Velocity –ve, N/S channel |
E | Velocity +ve, E/W channel |
F | Velocity –ve, E/W channel |
G | Mass position, vertical channel |
H | RS232 ground (RS232 control interface option) |
J | Mass position, N/S channel |
K | BUSY LED |
L | Mass position, E/W channel |
M | Power –ve (not used in sensors with internal DC-DC converters) |
N | Signal ground |
P | Calibration signal (all channels) |
R | Calibration enable, vertical channel |
S | Calibration enable, N/S channel |
T | Calibration enable, E/W channel |
U | Centre |
W | Unlock |
X | Lock |
Y | Logic ground |
Z | RS232 transmit from instrument (RS232 control interface option) |
a | RS232 receive at instrument (RS232 control interface option) |
b | Power ground |
c | Power +ve |
In sensors with the RS232 control interface option, the RS232 ground line (pin H) is isolated from the other ground lines (pins Z and a) using 10 nF decoupling capacitors.
As an option, sensors can be equipped with a 26-pin high-density “D”-type plug in place of the mil-spec connector.

26 | RS232 ground (RS232 control interface option) |
In sensors with the RS232 control interface option, the RS232 ground line (pin 26) is isolated from the other ground lines (pins 4 and 8) using 10 nF decoupling capacitors.
Waterproofed models have a 32-pin waterproof connector in place of the 26-pin output connector. These instruments are supplied with an adapter cable for connecting to a standard digitizer input.
The pin connections are:
