Use the 3M Scotchlok UR-2 connector with its special insulation displacement contact to create a reliable electrical connection to wires in communication cables. The conductor is inserted into the U-contact connector, creating a spring-loaded connection. This removes the insulation and presses all conductors together with a firm, elastic pressure in one motion. The conductor insulation does not need to be removed. 3M Scotchlok connectors are factory filled with sealant that protects against corrosion and moisture. They are also available in a dry version for indoor use. Various sizes and wire combinations are available to meet all requirements. Solid wire size 0.4 mm to 0.9 mm with a maximum insulation diameter of 2.08 mm.
