Coherent HeNe PSU Power Connector

Can anyone help me identify these connectors on Coherent HeNe power supplies? I'm not looking for the HV Alden, but the LV input one.

I've hunted through Digikey, but doing so is like searching for a needle in a haystack.

I want to price the crimper and connectors to setup several of these.

It's the same 4 pin connection used on P4 motherboards. I made a simple adapter to use a 12v DC adapter that has a standard 4 pin molex plug. I just used a P4 extension cable and a 4 pin molex -> SATA power adapter and soldered the needed connectors together. You can see it in this post:

I need to order the parts and another 12v adapter for my yellow head/PSU sometime soon.

Molex! Great clue, thank you. These are in the Mini-Fit Jr.™ Power Connectors family.

Modifying an existing cable may work, but I need male connectors to connect to the PSUs. Those cables I find by your description seem to provide female.

The cable i bought was a P4 extension cable and just cut it in half. It's kinda ghetto but I wasn't going to pay a small fortune for a pin extractor.

Newegg is out of the specific cable I bought but this is the same cable in a different brand.

To connect to the standard 4-pin computer PSU style molex I bought the cheapest cable I could find, a 4 pin molex -> SATA power, and chopped the SATA end off. Just make sure you join the correct wires if you build something like what I made. A reverse polarity can kill a HeNe PSU pretty quickly.

Yep looks like a Molex 4 pin. You could also just cut the connectors and hotwire them

Not everything we do has to be a hack.

And sometimes, the elegant solution is worth the cost.
