Scotchlok 3M type “Red Button” K3/UR3 Connectors are used for general butt splicing with 2 or 3 wires 19-26 AWG air core with maximum insulation O.D. of .066", and do not require any special tools. Designed for butt splicing voice and data communication cables with solid copper single-conductor wire. Double "U" contact in the button clamps down on the wire, strips the insulation, and grips the conductors in a moisture resistant connection. The connectors are filled with corrosion-resistant sealant at the factory to protect the connection against air and moisture.
Simply insert the matching pair of cables needed to be joined then press the connector closed using a flat surface or pliers. If using pliers, ensure to press evenly on connector surface to apply even pressure around full surface.When inserted, there are two internal connection bars to ensure a reliable connection to signal wires.
There is no need to strip the insulation on the individual wires as the IDC (Insulation Displacement Connectors) will cut into the cable just enough to make a moisture-resistant connection. Ideal for outside work as they are gel filled makReing them self-sealing, and will work equally well inside.
