Re: [PSUBS-MAILIST] RFC - Standard Thru-Hull Electrical Connector

["Jens Laland" <laland@artematrix.org>]

Hi all...

** I am hoping that the thru hull threads into pipe coupling as
** Frank mentioned.

It would therefore be interesting to know what size of thru-hull threading
the 10-pin connector version is furnished with.

My question :

Is it feasible to use a suitable pipe coupling that could possibly
accommodate both sizes (i.e. using an insert reducer for the smallest
4-pin connector)?

Reason for asking :

It would be a whole lot easier to conduct prototype testing of future
underwater sound equipment.

Sketches :

a) background

The above sketch shows the principle of binaural listening using acoustic
beam forming (with a prototype under construction).
However, another system, using electronic beam forming, is under planning.

b) required conductors for the following
  * 3 ea. hydrophones (each pair covering 120 degrees)
  * 1 ea. projector
  * Grounded Shield
  * 12VDC power to Hydrophone Pre-Amplifiers
