MMJ Stranded

I need a couple MMJ (and probably a couple spares in case I screw one up) connectors for stranded wire. I can use flat or round wire insert for this application.

None of my old sources seem to have them, and my last couple orders from Digi-Key got "lost".

I'll gladly pay for them and a flat rate envelope if you can get them in the mail today. I do PayPal.

I thought I had some but they didn't work. When I put my reading glasses on to actually look at them I realized they were for solid wire. Oops.

For those who don't know. MMJ is an offset locking tab modular connector that looks similar to an RJ-12 phone cord plug. It has 6 pins. Stranded type pins puncture the connectors through the center, and solid type pins skin the insulation off the sides. If you have good eyes or good reading glasses and plastic isn't to fogged and scratched from riding around in a box in your truck you can see the difference through the plastic.

Its looking like I am going to have to make an adaptor of some kind. Digi-Key and MCM don't even have them.

BlackBox has them. I ordered a few from them a couple weeks ago.

Thank you. This comment makes me nervous however.

"6-wire cable is for stranded or solid cables."

The Problem:

  1. If you use a penetrating stranded wire type on solid wire you risk it breaking the conductor and having a bad connection.
  2. If you use a skinning type solid wire type on stranded wire you risk the conductor just forming an oval and slipping between the skinning points and having a bad connection or even no connection.

No problem with the ones I have. The connection pins in the ones I have look like the same style as a punch down contact with a staggered split. I used them with stranded with no problem.

I think you got lucky. The staggered split ones are for solid wire. That's what I have. Or maybe the wire you used is a larger gauge and it made contact anyway. I've been doing phone work for a long time, and I've trace many a problem to somebody using the wrong modular plug over the years.

P.S. I could be wrong. I was wrong once before so it might happen again. LOL.

There is a variant that will work with stranded or solid, not sure if anyone but AMP (I think it was AMP) had them.

I was about ready to just make some jack and cord adaptors to use the solid wire MMJs I have when a little gold magic bag appeared in my mail box. I closed my eyes and wished for stranded wire MMJ connectors. I opened the draw string on the magical little gold bag. Several little stranded wire MMJs tumbled out on my desk.... Along with a steel 1943 penny, a USB card reader, and a power connector for an iPod. Weird.

Anybody need an iPod cord, or a USB SD card reader? The money I am keeping. Sorry.
