The 1-966067-3 is an insulated wire end ferrule designed for reliable termination of 1.50 mm² (14 AWG) stranded and flexible wires. It features a black plastic sleeve for circuit identification and a copper sleeve for gas-tight, secured connections. The ferrule has a total length (L1) of 14 mm, an insulation length (L2) of 10 mm, an inner diameter (d1) of 1.70 mm, and an outer diameter (d2) of 3.50 mm, providing precise contact surfaces for screw, push-in, and spring connection technologies. These ferrules facilitate clean and reliable wire insertion into terminal blocks and control devices, making them ideal for industrial and commercial applications where contact precision and conductor protection are essential.
