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.

6.2 5T high pass filter output option

The following table applies if the second amplification stage is being used to provide a high-pass filter (with unity gain). The same connector is used and the connector information above (in Section 6.1) applies.
