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

So, is there still any interest in a standard bulkhead connector? My main rationale for it was to connect OTS cables on any sub, but it seems like with the cheap Digi-Key source of OTS connectors it isn't needed anymore as everyone can make a cable set adapted to whatever bulkhead connector they are using.

It would still be nice to standardize for other reasons, but no longer necessary.

Thanks,

Alec

The OTS cables with "connectors" that I have are OTS factory made. They are intended to allow the SSB-2010 diver units to be used as surface units. When I intially purchased the SSB-2010s I used one as a surface unit and one in my sub. I cut one of the cables , soldered it back together with water stop pins and then potted it into a thru hull penetrator that I fabricated. This assembly has worked very well. By purchasing the connector ends that AL has spec'ed out and using either a commercially made thru hull penetrator or one you make yourself , It will be possible to have comms in any sub that wants to dive at the convention this year . I will post some pictures of the cables , connectors and comms etc. this weekend.

This really is a functional reliable way to go. I am very happy with the performance.

Al, thank you for tracking down a supplier for these connectors. A factory made cable with the two connectors cost $125.00 from OTS. I will be ordering some spares from DigiKey and saving some money.

I’m just referring to the OEM connectors they use. They probably make up their own cable assemblies in house and do the potting themselves with RTV or epoxy.

Again, I’m only going by the cables I saw to Dan Lance’s units which are as I described and used by police, military, etc. I’m sure they all buy their cables pre-made from OTS.

Regarding the bell unit, if it’s not a catalog item, I’m not sure how to go about getting detailed info on it not to mention getting my hands on one to physically look at it. Besides, I would doubt

they use the same transducer that they use on their portable 3 watt units. Their 10 watt surface only unit (STX-101) has a transducer where the cable is potted or molded directly to the transducer

and the only connector is at the end that plugs into the radio and is the same as the SSB-2010 units.

Al,

OTS sells what they call a bell unit, which says diving bell to me, and that would need a full-tilt bulkhead connector. It doesn't seem to be a catalogue item for them, but I wouldn't be surprised to find they have something to use that doesn't require a dose of RTV. Police agencies and the military are less than pre-disposed toward bandaids like that.
