A 10-12 AWG power pin in the Universal MATE-N-LOK family
The 770234-3 is the 10-12 AWG pin contact in TE's Universal MATE-N-LOK crimp series, carrying a tin-plated mating surface and crimp termination for power and signal circuits. The contact is rated for the 10-12 AWG wire range, and the tin finish supports moderate mating-cycle applications in dry environments.
Wire gauge difference from a series sibling
Within the Universal MATE-N-LOK pin family, the 770234-3 accepts 10-12 AWG wire, while the 926883-1 accepts 14-20 AWG wire — the crimp barrel and contact body are sized accordingly, so each serves a different wire-range bracket.
