3M Scotchlok IDC 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 is required.

• The small size of the 3M™ Scotchlok™ Butt Connector UY2 reduces the splicing bundle size to a minimum. The connector’s two ports accept two solid copper conductors, and include a factory-installed sealant to protect against corrosion and seal out moisture.
• Recommended installation tool includes 3M™ Crimping Tool E-9BM.
