I have gotten the task of finding an appropriate connector for our application, but given so much information there is on connectors, I don't even know which information is relevant.

So this is the task;

I have a cable that has a strand of 10 smaller insulated wires inside. I must find an appropriate connector that will guarantee IP 67 protection.

I measured some of the dimensions of my cable and they are;
Cable outer diameter = 6.5 mm
Wire insulation outer diameter = 1.1 mm
Wire copper cross-section = 0.205 mm²

My question is where do I search for the connectors? Is it at the sellers like Mouser and Farnell, or should I try looking straight to the manufacturers? How do you find the right connector in the vast sea of all the possibilities?

Thank you all.

Additional information:

The connector is going to be used in automotive application. The wires will transmit mostly digital signals for communication and a pair for supply power of 12V no more than 1A. It should be wire-to-wire attachment.

    \$\begingroup\$ You should first identify what voltage and current ratings are required and what type of signals it carries. Next, where is the connector attached to? (BTW, IP67 is quite high and probably reduces the sea to a lake...) \$\endgroup\$ Commented Jun 5, 2019 at 9:33

  • \$\begingroup\$ IP67 means it has to be water resistant for at least 30 minutes at 1 meter depth. Did you start by searching for 'water proof' connectors? Is the interface a standard one or is this totally custom cable? \$\endgroup\$ Commented Jun 5, 2019 at 9:39
  • \$\begingroup\$ Well, I can find plenty of different kinds of connectors, what I am wondering is, if there is a way to do like a wide search like the sellers have where you just input the filters. I run into problems when I start looking at some manufacturer and after 30 mins I see that either, my wire diameter is inappropriate or they do not have the right numer of pins. \$\endgroup\$ Commented Jun 5, 2019 at 9:44

    \$\begingroup\$ Use Digikey, their parameteric search is good. Start with 'connector', then 'circular connector, then 'more filters'. The 'ingress protection' filter actually throws up zero hits for all connectors with IP67 in the rating, but shows more than 3000 with IP68, which is a better rating. Within those, you can now use the 'number of positions' filter to exclude those with too few, or way too many. Filter on current and voltage as well. I don't see a 'wire size' filter, but current will get you close. \$\endgroup\$ Commented Jun 5, 2019 at 9:53
