Molex connectors for R22 BUD cell

Divejunkie

Anyone found out what the alternative connector is for the Teledyne oxygen cells? Has anyone used the Teledyne R22D cell, it looks identical in spec to the R22 BUD?

I am sure you will find many people here have been using the R22D on the Inspiration as well as on most other units.

Go to Oxycheq.com website and read a small write-up that Patrick Duffy did to explain about the difference between the 2 sensors.

Now, on the Evolution, the connector is different (not Molex) and I am not aware of alternative choices of sensor yet... (hint! hint!)

www.rapidelec.co.uk have a big range of connectors. If it's an electronics component then it's probably there.

Teledyne r22d and APD r22-bud are the same cells..

if you use a high quality connector with gold pins they should last a long time..

These connectors should always be crimped (per manufacturer specs) and not soldered.. however some types of wire will wick water on the exposed parts so YMMV.

Molex 3 pin connector P/N 22-01-3037
pin part # 08-52-0123 or 08-56-0110 (better pin)

ANy good supply place should sell these.. When I order them I get them from mouser

The new connectors for the vision electronics? Easy, it's an RG174 mil-c-17f co-axial cable, and RS components NZ have the connectors.

Connectors 245-5042
Crimper 252-2473

Just don't wince at the price of the crimper.....

Of course, once you make up a cable to fit the end of the existing cables, you can put an RG174 to molex adaptor in the lid and use whichever cells you like... You know it makes sense to introduce points of failure......

I am sure Martin Parker just love to see this kind of discussion about how circumvent the new connector...

Hi Gaz

They are the same I have them in my unit.
Will be back in the UK tomorrow, I will call you nect week and I will show you one of them

Maplins have a connector that is identical to the Molex connector.
If I remember correctly I bought five packets (each contain 5 molex connectors) and I bought 5 packets of pints. Each packets has 10 individual pins taht you can crimp or solder onto the wires then just push fit (and they lock in place) in the connector body.
I'll see if I can dig out the part nos.
Total price was a few £.

hello joe, the best ever connection we get with the molex is the following:

pre-solder the wire, then crimp it on the connector with the correct tool, and then solder it again with a small amount of solder
always use the gold plated one
then grease the connector well before you slide it in the plastic part, (to prevent corrosion due to humidity)

this way the connector lasts for ever, and the contact stays perfect

since we do this with the rEvodreams, we NEVER have bad contacts!! (at the start we had... but we learned a lot :-)

regards
paul

The other thing to do is to use a SMALL amount of liquid electrical tape on the connection after you crimp and solder it.

This seals the wire penetration. Beware that the solvents in this stuff are NASTY, so you need to leave it out and exposed for a week or so after you do it, and keep the amount used SMALL.

IMHO manufacturers should be using 100% tinned wire in the head as bare copper is simply unsuitable in the marine environment. This seems to be ignored more often that observed, however, and is a large part of the reason that cell connections with the Molex connectors get flaky over time. If you use the high-quality pins the problem won't be there - it will be at the wire/pin interface and up the wire jacket.
