10-32 to 3.5mm Cable For DPA SMK4060
« on: February 24, 2013, 01:41:01 AM »
I wanted to be able to connect my DPA 4060s to a battery box with 3.5mm jacks so I could run directly into my R09HR without a pre.  Last night I put together a cable with 10-32 RF (aka microdot) connectors and a 3.5mm plug.  I learned a lot and I think the cable came out decent.  Below are a few pics and notes.

Pasternack carries a bunch of RF connectors and will sell you them in quantities of 1 or 2, but they are not cheap and they will add service fees and shipping to orders under $100.  Here's a pic of a few 10-32 connectors (L to R: PE44357, PE44359, PE44360) along with a 4060 and Neutrik right angle 3.5mm plug.

I decided to use the vertical PCB Mount connectors PE44359 http://www.pasternack.com/10-32-female-standard-thru-hole-pcb-connector-pe44359-p.aspx and had some Mogami 2368 single conductor shielded wire that is nice and thin.  http://www.markertek.com/Cables/Bulk-Wire-Cable/Bulk-Audio-Cable/Mogami-Wire-Cable-Corp/2368.xhtml

After tinning the wire I soldered it to the 10-32 connectors and added some heatshrink.

Next I wrapped the base of the 10-32 connectors with copper foil to shield the open part of the assembly and also create a "cup" to hold epoxy potting.   I soldered the copper foil to the edge of the 10-32 connectors.

I wrapped both connectors with masking tape to make sure no epoxy would leak out of the copper cup onto the threads, then partially filled them up with 2 part epoxy using a baby medicine syringe.   ;D

Once the epoxy partially set, I crimped the copper foil around the cable and started to build up a few layers of heat shrink.

I finished the 10-32 connector ends off by covering the whole thing with adhesive lined heat shrink.

I tied the two lines together in a couple spots along their length with adhesive lined heat shrink.

Finally I added a Neutrik NTP3RC-B 3.5mm Stereo Right Angle Mini Plug http://www.markertek.com/Connectors-Adapters/Audio-Connectors/3-5-2-5mm-Mini-Connectors/Neutrik-USA-Inc/NTP3RC-B.xhtml

Finished cable shown with DPA 4060s.  Tested fine.

Nice work! I had Chris Church make me the same thing which works well for my 4061s. This is a very informative how-to if you have the skills, tools, and DIY mentality.

Thanks for sharing.

Nice.

When I had the 4060's I wanted to do a cable like that for super low-pro operations where the DPA pre-amp was too big. Never wanted to do the straight 4060 > 1/8" because I wanted to use the DPA amp most of the time.

Never got around to it though.

Thanks guys.

Yea I wanted to still be able to use the mics with the P48 XLR adaptors into a full size mic pre. 

4060 > Batt Box > R09HR has a nice size to quality ratio though.   ;D

looks good

any problems getting two of those cables into the neutrik end?

also, anyone know of a similar cable to the mogami but a different brand? (no mogami in europe as far as i know)

No the Mogami 2368 is very thin. No issues.
