Cardas GRFA Double RCA measurements?

[dsavitsk]

Does anyone have measured dimensions for the Cardas GRFA DBL RCA jacks? I am trying to do a PCB and case layout, and Cardas doesn't give quite enough information away to actually accomplish this. Even better, anyone have an Eagle part library for these?

Drawings for an alternative part from another manufacturer (Vampire?) that is of decent quality would be fine, too.

You might try asking Headroom if they'd share this information sine they've long used these parts in their amps.

I'm also curious what information you think you're missing? Maybe I can help.

I need pin diameters, spacing between those ground pins, and space from pin to panel, and probably vertical distance from board to drill centers. If you can measure some of that, that would be very appreciated.

Thanks

FWIW

Thanks, Nate!

Please be aware that while the dimensioning program that I used matched what Cardas had shown on their drawing Cardas also state right on the image that it isn't a technical drawing. I'd guess what I show will get you close, but wouldn't bet my life on it.

Peter Daniels uses these in his builds so contacting him on DIYAudio could help. I quite like this Vampire part, I have a few which I bought from Justin and I could measure them for you.

Has anyone tried emailing Cardas to see if they could provide a technical drawing? And yes, if Headroom would share, that would be great. Tangent doesn't happen to have these in his Eagle stuff does he (can't remember the link).

No, I wouldn't either -- some of your numbers don't add up. The width of the whole thing is listed as 0.63", but you have the pins that are within this being 0.81" apart. Same with the distance between the L and R signal pins -- you have 0.7", but it must be at most less than 0.622", and if the original drawing is to be believed, it should be exactly 0.273". Are these off by some multiplier perhaps?

Those would be fine -- a little more expensive, but not enough to break the bank.

I did, and they said they don't have a better drawing, though they were able to provide a few more numbers. And, I shouldn't say it as I know how these things get abused, but they are sending me a sample to measure.

Here are some numbers from Cardas
