PJ-068 Microphone Connector
Hello everyone
My Telex Echelon 20 microphone connector broke, so I had to buy a replacement connector. This PJ-068 type connectors are a hard to find item (and expensive)! I'm trying to find a solution to connect the cables to the correct terminals. The microphone cord has only two connections, and the connector, according to the diagram, appears to have three terminals. Where do I weld each wire? Thank you very much in advance! Here are the pictures: http://s7.postimage.org/y4gs2xnx7/Photo_1.jpg http://s7.postimage.org/wrz311qhn/Photo_2.jpg http://s7.postimage.org/ahb812t7f/Photo_3.jpg http://s7.postimage.org/5wp1m59i3/spj068_drawing.jpg |
Hi
the tip is press-to-transmit, a hangover from the days of hand held mics. Mic connections are mic+, the ring behind the tip and mic-, the body of the PJ-068. So your blue wire goes to the ring, and braid to the body ('sleeve'). |
So, as the headsets doesn't have a PTT the tip terminal is useless, right?
The blue goes to the ring terminal, the braid to the sleeve terminal, and the tip remains empty. Am I correct? |
The photo you have shown LOOKS LIKE a stereo headphone plug, and IS NOT a PL-068 or equivalent. I'm pretty sure the shank of your plug is 0.250" dia. and not 0.206". Better to measure and be sure.
There are WWII surplus PL-068s still available, but not easy to install because of the wire connections used (very small ring-type lugs). |
Fair_Radio_dot_com has them - Cat. No. PL-68-U (doh!)
But as I've cautioned, making the connections isn't easy. |

If only I've found this earlier: XLR5 to GA headset adapter [Archive] - PPRuNe Forums GA 0.25" 2-pin jack (earphones) Tip - Ear+ Sleeve - Ear- 0.206" 3-pin jack (mic) Tip - No connect Ring - Mic+ Sleeve - Mic- |
OK - just wanted to be sure! :ok:
