Chris, Have you considered using heat shrink tubing and potting compound? You shrink one end of the tube, then add some potting compound, then shrink the remaining part of the tubing. That would be weather proof Just my $0.02 Jean-Paul Forwarded Message: [EE] Potting bare cable connections (low volume)Friday, July 16, 2010 11:44 AM From: "Chris Smolinski" To: "Microcontroller discussion list - Public." Does anyone have suggestions for materials/techniques for potting bare cable connections? Basically, i'm going to have three audio cables (2, 3, and 4 conductors) connected to each other at central location (possibly with a resistor or two between some of the wires). Rather than use a junction box, I was thinking of just potting it. Has anyone done something like this before? I'll need to select a potting material, and figure out something to use for a mold. Any suggestions? Anything else I am overlooking? Does the cable jacket material affect the selection of the potting material? \ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
