Title: 1 pin molex
Post by: javila on May 21, 2010, 11:11:22 PM
where can I find a one pin molex connector. I have been looking at the tutorials but the only things I can find are the
ones for 2 or more pins.
Thanks

Erm, probably easier if you make your own by cutting a 3 or 2 pin molex up.
They do exist but are not very common.

Could you use a 2 pin molex but not connect one of the pins?

The idea behind molex connectors is that they lock into place, and also only connect correctly 1 way round so cutting one up defies the object of using a molex.

You could also use a single header pin and solder a wire to a header female connector.

For singles, I just use a pin with no molex housing - I just shrink wrap it.

I just did a search and couldn't find any single housings on mouser or digikey, but I've used them in the past so I know they exist.

There are also Molex connectors that do not have polarization (can be connected either way around).

You could either cut a 2 way or 3 way connector, or you could just use the crimp pin either as is (if there are no shorting issues) or covered with heat shrink tube (or whatchamacallit...)

Edit: Admin beat me to it :P That's why he's THE Admin i guess....

Hi,

SIngle pin connectors here (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=60_190&products_id=1740&zenid=cfdbb76cbb0418a64d609e105038d3a8) (and several other places).

Just using heat shrink around a single crimp connector will make it difficult to get it nover a pin.
