Telephone Insulation Displacement Butt ConnectorThe UP2 connector is dry for flame retardant applications where moisture resistance is not needed.It accepts two wires within wire range of 0.4-0.7 mm (26-22 AWG) and insulation diameter up to 1.52 mm/.06″.It is made of polycarbonate and is UL Listed.These butt connectors employ a specially designed, wire insulation displacement contact to make a reliable electrical connection to each wire. A live-spring joint is made by driving the wire down into the U contact connector. This simple process displaces the insulation and grasps all conductors with a firm, resilient pressure, all in one motion. No stripping of wire insulation required.Picture is representative of the product. Actual product may vary slightlyTEL CON UP2
