PIDG spade terminal, 16-22 AWG, #10 stud
The 52931-1 is a PIDG-series insulated spade terminal from TE Connectivity AMP Connectors, accepting 16-22 AWG wire and terminating to a #10 stud. The tin-plated copper contact is crimped onto the wire; the nylon insulation sleeve is color-coded red for the wire range and covers the crimp barrel with a 0.080" to 0.125" insulation diameter window.
Serrated crimp and insulation grip
The serrated termination bites into the conductor strands during crimping, increasing pull-out force compared to a smooth barrel — the nylon sleeve then grips the wire jacket to reduce strain at the crimp transition.
