What is being used out there besides the fischer connectors and what kind of luck have you had with them?

Bulkhead connections and a soldering iron. Fixes those connector woes permanently. I even solder my sensor lead wires directly to the sensors.... and bulkhead connections cost about $5 each from McMaster-Carr in either nylon or brass.

Simple = best.

Seaconn full ocean depth connectors. Take them to the bottom of the bottom of the sea if you like.

You could also use Lumberg cables.

Seaconn or Subconn? Is there another one that starts with an I? I heard 2 names while at DEMA and didn't write them down.

Thanks.

What category are those in? (McMaster can be "fun" if you don't have the magic keyword!)

Nylon Liquid-Tight Cord Grip Fittings sample P/N 69915K51

Nickle-Plated Brass Liquid-Tight Cord Grip Fittings sample P/N 6907K12

Many sizes. P/N's given are for 1/4" wire. Available larger or smaller and with or without flex strain reliefs.

Also, don't forget that Swagelok fittings can be used to pass cable thru a bulkhead. They provide a nylon ferrule to replace the stainless one. This is what has been used on many milspec cable pass-thrus.

Better pick up some of these too:

4912K16 miniature chrome plated brass ball valves.

This is a chrome plated brass ball-valve that I use to isolate KISS 02 flow and for other LP gas control uses. Other versions are available in the same part numbr range. Even the handle screw is stainless... costs $5.21. Buy similar stuff from Swagelok and pay $50. Take your choice... ;-)

Now, payback time for me: Who has P/N and supplier for the 2 pin Fisher connector used on old VR-3's? Mark-15 is going to get an internal VR-3 cell.

Oh, you're talking about what amount to light cable glands, blocking the cable (e.g. running epoxy down the center), and just wiring direct.

Got it.

Seaconns are seriously expensive.

Epoxy behind a $1 stereo jack can withstand 1400msw. Just beware the Chinese jacks where the rings can rotate, as they make poor connection. We use miniature stereo jacks whenever we do not need more than 4 wires (you get double stereo jacks too, with 4 wires). Advantage: small and you can rotate them to get the cable run you want. We made our own jack type connector for 7 connections plus a fibre: still cheaper than a Seaconn. Seaconns are also big, especially by the time you have put everything else on, and they normally only sell the male pre-wired to a cable.

I'd love to see a picture of this connection if you've got some available. Thanks.
