Question about DACT attenuators
« on: 16 Jun 2007, 03:03 am »
Specifically the stereo version...

Can anybody tell me what are the minimum clearances for all 3 dimensions on the inside of a box you need to accommodate the stereo attenuator?

What about maximum panel thickness for mounting hole, and diameter of the hole?

I'm trying to plan a project and am working on coming up with the basic overall dimensions.

Thanks,

Jim

Here's the front panel cut out in mm...



The rest of the spec sheet is here... DACT

HTH!

Gordy,

Thanks -- I got many of the dimensions like the shaft and mounting hole diameter, etc. but without being able to see, the rest of the dimensions don't do me much good as they seem to refer to the drawings -- which I can't see.

Hi Jim,

I didn't realize you were using a reader, here's the info you needed, I think! 

The shaft diameter is 6mm, the body height is 36.5mm / 1.44 inches, body width is 25mm / .98 inches, body depth after mounting looks to be 43mm / 1.69 inches and the maximum panel thickness would be 7mm as the thread depth is 9.5mm and the nut thickness is 2.5mm.  PM me if I missed something again or if you've anything else to add!

Gordy

edit:  you may need to allow for some height as the connector pins exit the bottom and are not included in the 36.5mm measurement...

Gordy,

Many thanks.  It looks like a cube 2.5" on a side should be enough clearance for everything.  Right now I'm just gathering rough dimensions so I can figure out the overall chassis size.  Now I'm just waiting for my power transformer, which I won't know the dimensions of until it arrives because Jack Elliano doesn't design to size restrictions -- he designs the transformer to be the right size for the electrical specifications -- which is as it should be.
Thanks again,

Jim
