Nickel-plated copper contact, 0.032\" (0.81mm) thick, accepts wire insulation diameters from 0.035\" to 0.075\" (0.89mm to 1.91mm). ## Same-series peer contrast: non-insulated Solistrand The 1577618-1 is an insulated PEEK terminal; the Solistrand, Strato-Therm 133521-1 is non-insulated, gold-plated, and uses a #8 stud for 18-22 AWG — the 1577618-1's PEEK insulation and serrated termination suit applications requiring a dielectric barrier at the crimp.
