Power ring terminal for bolted connections
The TE Connectivity 63166-5 is a power ring terminal accepting 12-16 AWG wire, terminated by a screw through the ring lug. This is a bolted connection — the ring slides onto a stud or bolt and is torqued down, not crimped or soldered. It is the terminal end of a power cable that lands on a busbar, battery post, or equipment ground stud. The Tape & Reel packaging suits automated pick-and-place for high-volume harness assembly, though the screw termination itself is a manual step.
Wire gauge fit and termination workflow
The 12-16 AWG acceptance covers the common power distribution wire sizes in industrial and automotive secondary circuits. A 12 AWG stranded conductor carries about 20 A in free air; 16 AWG covers control and signal power runs. The screw termination means the installer strips the wire, inserts it into the barrel, and tightens the screw — no crimp tool, no die set. The ring ID is sized for the stud, though the exact stud diameter is not listed in the spec; the ring is designed to mate with a standard bolt or screw that fits through the lug eyelet.
