The tin finish on the brass contact suits moderate-cycle-count applications where cost per termination is a factor — think industrial control panels, automotive harness junctions, or power distribution within an enclosure where the mating cycle count stays under a few dozen over the product life.
The 18-22 AWG wire range covers the typical signal and moderate-power circuits in industrial and automotive harnesses. The crimp termination is field-reliable with standard tooling — no soldering or special equipment required. The stamped construction keeps the per-contact cost low for volume builds, and the bulk packaging (not tape-and-reel) means it ships loose for hand or semi-automated crimping.
What is the difference between 66592-1 and 66592-2?
The 66592-1 carries a tin contact finish, while the 66592-2 is gold-plated. For a harness that sees frequent mating cycles or operates in a corrosive environment, the gold variant (66592-2) is the better choice. For a fixed installation where the contact is mated once or cycled only during maintenance, the tin 66592-1 saves cost without sacrificing performance.
