Edge connector for dbx 900 Series cards
« on: May 16, 2017, 05:25:15 PM »
I have a couple of dbx 903s to rack up. The contact pitch is 4 mm, as close as I can measure it, which seems odd for a US-made product. The closest thing I can find at Farnell is a 3.96mm pitch connector

The dbx connector has 15 ways. I have found a couple that look close:

Any suggestions as to the ideal part? Or does anyone have a couple?

Many thanks

It's 0.156"  = 3.96mm

That should get you started.

The standard API car edge connector is working fine. 15pins @ 3,96mm.
Attached a pic of my dbx 900 measuring adapter for my 51x measuring adapter :-)

Those card edge adapters are way cheaper with PCB pins purchased from Jeff Steiger or me, you might ask Cemal in the UK.
SSLtech: No bypass, I don't believe in it.
Gus: I think this build might have problems with DIY builders that don't know things like ohms law.

Ah, many thanks. I didn't know it used the same connector as API cards.
I wonder where 0.156 inches came from? It's not an obvious pitch - or not to me anyway

5/32" = 0.15625", FWIW.

Five thirtyseconds of an inch - that's as oddball a measurement as I've ever heard!

Thanks, Gene

There are a couple of complete racks on ebay for pretty cheap (one under $100usd).  Dont know if you're looking for a full rack but you could certainly part it out.

Thanks for that. Sadly by the time they get to the UK they will have doubled or tripled in price. I believe they are quite heavy so shipping + purchase + VAT on the whole lot will make one quite expensive
