The tin-plated copper contact is crimped onto the stripped wire, and the nylon insulation barrel restricts the insulation to keep the conductor visible at the crimp window. Overall length is 0.866\" (22.00mm) with an outer edge width of 0.283\" (7.20mm). The insulation accepts wire diameters from 0.049\" to 0.070\" (1.25mm to 1.78mm). ## Sibling ring in the PIDG line The 131648-1 is the same PIDG ring terminal for a #4 stud but accepts 20 AWG wire and measures 0.311\" (7.90mm) wide and 0.917\" (23.30mm) long. The 131644-1 handles the heavier 18-22 AWG range and is slightly narrower and shorter — match the wire gauge to the terminal before crimping.","metaTitle":"TE 131644-1 Ring Terminal, 18-22 AWG, #4 Stud, PIDG","metaDescription":"TE Connectivity AMP Connectors 131644-1 PIDG ring terminal, 18-22 AWG, #4 stud, tin-plated copper, insulated, 0.866 in overall length.
