Insulated ring terminal for 16-22 AWG
The 55936-2 is a PIDG-series circular ring terminal from TE Connectivity AMP Connectors, accepting 16-22 AWG wire with a #1/4 stud size. The tin-plated copper contact and 0.031" (0.79mm) thickness suit general-purpose power and signal termination where corrosion resistance is secondary to cost.
Black nylon insulation, serrated barrel
The insulation is black polyamide (nylon), covering an insulation diameter range of 0.080" to 0.125" (2.03mm to 3.18mm). Serrated termination inside the crimp barrel grips the conductor to improve pull-out force.
