Re: [time-nuts] Special connector for Symmetricom X72 rubidium standard

Chris,

One source of that connector is an HP C8231A cable for a Deskjet 450.
It's used to connect the printer to a DB-25 parallel port. The connector
fits the X72, but there are only 25 leads in the cable.  I haven't tried
to use it so I don't know if the missing lead is important or not.  The
cable isn't molded so it might just be possible to add the extra wire. I
opened it up, but I can't tell.  It looks like it's an IDC connector.
The connector is stamped with the manufacturer's logo of 'JST' (
www.jst.com ).  No part number, though.  I looked at the web site, but
didn't see anything close.

Dear all time-nuts list members,

I am looking without any success for some Molex plugs (52660-2651) to
connect to my X72 time standard.
Molex told me that these connectors are obolete since 2010.
I made some recherches at the Molex competitors but all told me that
they do not have 1mm pitch connectors in
their program.
Is there anybody who can help me getting some of these connectors?

That would be very kind and you will set me happy again...

Best Regards

Chris

If you have it open, can you tell which is the pin that's missing?
Maybe that one isn't needed and thus can be ignored.
