Faston PIDG 640174-1 — what it is
The contact is tin-plated brass; the non-mating end is insulated with a red/black-stripe sleeve. Overall length is 0.800" (20.32mm), insulation diameter 0.135" (3.43mm).
Crimp termination and wire fit
Crimp termination, free-hanging (in-line) mounting. The insulation support crimps onto the wire jacket — the 0.135" (3.43mm) insulation diameter matches the 18-22 AWG range. Tin plating on the brass contact keeps the interface corrosion-resistant for general-purpose signal and low-power circuits.
