What are the specs for J4, the AD2 external power connector?

[ledlighter]

What are the diameters for the barrel and pin of J4, the external power connector on the AD2? This connector is J4 in Figure 23 in the reference manual, but I can't find any specification. This type of connector has several common sizes for both parts. Thanks for the help.

Hello,

It is a coaxial connector 6mm x 2mm

Best regards,

Are you sure? Do you mean 6.0 X 2.0 mm or are these rounded numbers?  Digikey has a wide variety of this type of connector, but none are 6.0 mm OD. It would be strange for this to be a non-standard and hard-to-find size. The OD's near 6 mm that Digikey has are 5.5, 6.3, and 6.5 mm. The reference material available is really short-sighted for this connector.

Attached here you'll find the datasheet of the connector. The model used is DCCH-CAP-B. In the part list of the AD2 at J4 connector all the information I could see is its part number and the dimension which was 6mm x 2mm.

Thank you; that is helpful. It appears to me, from the drawing, that the entrance hole diameter is 6.0 +- 0.2 mm, so the 5.5 mm barrel size would be appropriate. I do not see a tolerance for the pin diameter, just the 2.0 mm diameter. This is subject to checking with real hardware, of course, but I'm going to try 5.5 X 2.1 mm.

I appreciate your help.

Hi Ledlighter,

Was this 5.5 x 2.1 connector the correct one?

Thanks a lot!

Hi Albert,

Yes, the 5.5 X 2.1 mm coaxial DC power connector is the correct size.

Thank you very much @Ledlighter , you’ve been very helpful! 
 

Asking to Digilent people is just useless .. 3 times I asked something .. not a clear response from them. 

Have a very nice Christmas!
