Standard dimensions of panels (thickness and Dzus holes)

I thought I should start this thread so we can easily find this info.  This thread is only for listing the standard dimensions of all the panels.  So lets list the standard thickness of the panels and the dzus locations.


PANEL THICKNESS
Light plate thickness is spec’d at .230 ±.023”. The length and width is spec’d to be 0.047±.016” smaller than the mounting plate the light plate overlays.  Typically mfgs use a light panel thickness of .250" (1/4")

The backplate is .062" (1/16") thick.

DZUS hole distance:

The Dzus rails have holes every 0.375 inches

Thanks guys this is very useful information.
Do you mind putting them in 'real' measurements please  
You know...  mm  

[falcon24]

That would be 9.5mm in real measurements  :wink:

Thanks Dave, good to see people here speak real English.   :wink:

I put all available info in a drawing, together with the Dzus T and L rails.

All panel widths are multiples of 9.53, they are like rack mount audio equipment, so I use U (4U, 6U etc) to describe them.

The smaller ones are 4U (Audio 2 and some blanks), the bigger are 13U (UHF and FltCtrl).
Dimensions with (-) are absolute maximum (panels touching). Actual values are 0.3-0.8mm smaller. For the difference between the lightplate and backplate see Jim's post above.

If I forgot a dim let me know.

I have a few panel design questions relating to screws, switches and lights. What are the cutout sizes for both the lightplate and the backplate for these? I'm pretty new to this stuff atm. Are there standard names for the specific types of switches and lights I should be looking for? I whipped up an initial try at getting the layout of the Test Panel done, but I'm missing the above hole dimensions. Thanks.

I forgot to mention, I'm doing my panel layout in Adobe Illustrator. Will I be able to export that out to a format that a CNC machine can use with a little tweaking? My plan is to do the layouts of all the panels in Illustrator while I slowly build my first CNC machine. Thanks

I haven't used Illustrator but since it's a vector graphics program it should be able to export to *.dxf or *.dwg (you can check this out). Even if it can't, I could import them into Corel Draw and translate them to *.dxf or *.dwg for you.

Nikolas

P.S/ Those are pushbuttons, not lights (the white, round ones). I'll see if I can find some dims.

Well, if you want, I have a Solid Works file for this back plate and light plate.  I took the dims from the real deal.  I can export them however you like, just let me know.

Version 9 and 10 of Illustrator will do a dxf export, however you would need to be careful about the layers of the Illustrator files.

If I were you, I would take up Dr. Creases' offer.

Standard toggle switches need a 0.484 inch (31/64) diameter mounting hole.  That should work for both the mounting plate and the illumination panel.  

If you want to use the locking/indexing ring a second hole is required in the mounting plate only.  0.125 inch (1/8) in diameter, the center of this hole is located 0.370 inch from the center of the toggle switch hole.

The back side of the illumination panel will also require a counterbore or chamfer around the toggle switch hole of the illumination panel to allow for the switch mounting nut.  The counterbore should be 0.688 inch in diameter and 0.100 inch deep give or take.  Some guys are just putting a chamfer around the hole.

The illumination panel mounting screws are usually No.6 and would have a 0.149 inch diameter hole (#25 drill bit).  But this only applies if you are just going to use the screws with nuts on them.  The MIL-SPEC panels normally have gromments installed to prevent the screw from crushing/shattering the illumination panel.

[oldman]

Just curious, are you going to be using MIL-SPEC components or commercial substitutions?  Some items have similar dimensions, but not exactly the same.

[Nikolas_A]

Does anyone know the diameter of the white push buttons? Also their height (measure from the backplate or the lightplate).

Nikolas,

I have seen different types of those Otto pushbuttons, the difference was mainly the way they attached to the panels (Front or back)

The ones i have here on my TEST panel are of the following dimensions:

white button diameter: 9.36mm
scew inner diameter: 14.75mm
screw outer diameter: 21.57mm (it's hexagonal. Side to side is 18.94mm)
thread from resting plate (that comes behind the backplate panel hole) to the button: 11.4mm
the button is 6.97mm high. Depressed it's only 4mm high
diameter of the resing plate is 22.2mm



Hope that helps
