Is the wire power or signal?

Its just that I would (based on school of hard knocks during whale
research) avoid any penetrations of the case if at all possible.
A signal might be able to be transferred optically (if window
available) or inductively.
Power could definitely be transferred inductively... discussed on the
PICLIST previously (e.g. Russell McMahon 26 Jan 2000).

A connector doesnt require much development admittedly BUT the
connectors were the fun little parts of our Whale song recorders
that used to fail in the field.. the field being outer Islands of Tonga
or in the midst of a Whale Stranding.

Some real connectors that actually will work (custom made) can
be seen in a book called "How to build and use low cost
Hydrophones" by Frank Watlington"  a TAB Book
 ISBN 0-8306-9846-9 or
 ISBN 0-8306-1079-0

The connectors are substantial assemblies.

BTW Plastic, Glass or Gold seems to be the only things that
survive salt water corrosion in my experience.
