The 3M 7100165190 is a specialty terminal designed to create a permanent electrical and mechanical connection to stranded copper wires. This snap plug connector features a round tongue for mating with a receptacle, enabling separable and reusable connections. It's suitable for applications requiring secure wire termination and is often used in building wire installations. The nylon insulation provides insulation grip, and the brass terminal with tin plating ensures reliable electrical contact. Proper installation using a 3M Scotchlok crimp tool is crucial for optimal performance and strain relief may be required to prevent accidental separation.
