Overview

Termination sleeves consist of a heat-shrinkable, transparent, polyvinylidene fluoride sleeve with an inner, pre-fluxed, solder preform and two thermoplastic sealing inserts. When heat is applied, the solder melts and flows to provide a superior connection between the ground lead and the shield. At the same time, the two thermoplastic sealing inserts melt and the outer sleeve shrinks to provide an environmentally protected termination. Otherwise, they are essentially the same.

Excellent way to join wires and have a solid connection. You must watch for some possible solder leakage that could result in a short. Just clean up the end.

Q: For the soldering sleeve 11-07902, what does the .125 mean? Is that the length of the sleeve or diameter of the inside? How can you tell what wire gauge can be used with the sleeve?

For 11-07902 the .125" is the diameter of the opening. You can fit between 2 and 4 22 gauge wires inside. After placing under a heat gun the sleeve will melt to the exact size of the wire.
