CMG-5T
6 Connector pinouts
6.1 5Ts with high gain output option
The 5T sensor has a single connector for both power and signal output.
The following details apply if the second amplification stage is being
used to provide a high (10 ×) gain output channel.
This is a standard 19-pin “mil-spec” plug,
conforming to MIL-DTL-26482 (formerly
MIL-C-26482). A typical part-number is
02E-14-19P although the initial “02E” varies
with manufacturer.
Suitable mating connectors have part-
numbers like ***-14-19S and are available
from Amphenol, ITT Cannon and other
manufacturers.
