The TE Connectivity 160644-3 is a tin-plated brass wire-to-board terminal, part of the 160644 series, designed for 16-20 AWG wire. It terminates by pressing through a hole in the PCB — a through-board style that locks into the board without soldering the contact itself, though the wire connection is crimped. The tin finish keeps cost down for applications that don't need frequent mating cycles, like a one-time harness assembly inside an enclosure.
Wire Fit and Insulation Clearance
The terminal accepts 16-20 AWG stranded wire. The insulation diameter must fall between 0.090" and 0.126" (2.29 mm to 3.20 mm) for the terminal to seat fully in its housing.
