Crimp termination, accepts 20-24 AWG wire. The brass base material with gold finish resists corrosion in industrial and instrumentation environments where the connector sees field service.
Wire Range and Termination — Crimp for Field Harness Build
Rated for 20-24 AWG stranded wire. The stamped contact body uses a crimp termination — no solder, no special tooling beyond the standard HDP-20 crimp die. This makes the 66506-9 a field-replaceable pin: cut the old crimp, strip fresh wire, and re-crimp into the same housing cavity.
