Re: DEC backplane power connectors

I have found this catalogue useful to browse when trying to find the appropriate housings and pins. https://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv=82181_SOFT_SHELL_CATALOG=CS=EN It covers both the commercial Mate-n-lok used in the PDP-11 and universal Mate-n-lok used

Re: DEC backplane power connectors

I have a feeling there are two shell designs for the 6 pin. The one on my DD11-DF that I want to mate has detents in the corners while the catalog picture for the 6 pin on your part number shows a square in the center of the side. I'm pretty sure I've seen that style 6 pin on some of my other

Not at all a waste. I have that page bookmarked. Doc On 1/27/21 11:51, Noel Chiappa via cctalk wrote: > Are the power connectors on the DEC PDP-11 backplanes (e.g. DD11-DF > 15pin and 6pin) Molex or other? > Are they still commonly available?

I wish I had seen it before I ordered. I may have gotten the wrong 6pin shell. --tom On 1/27/21 11:51 AM, Noel Chiappa via cctalk wrote: > > Are the power connectors on the DEC PDP-11 backplanes (e.g. DD11-DF > > 15pin and 6pin) Molex or other? > > Are they still commonly available?

Re: DEC backplane power connectors

Well, they vary for what you may need of course, but in my case, I wanted to connect to existing DD11-DF female shell/male pin 15 and 6 contact connectors. Searching the te.com site, there are some similar parts, but the ones which look correct are: Commercial MATE-N-LOK-S, 1-171196-0 (digikey

DEC backplane power connectors

Are the power connectors on the DEC PDP-11 backplanes (e.g. DD11-DF 15pin and 6pin) Molex or other? Are they still commonly available? --tnx --tom
