This part is a ring-shaped core frame with multiple grooves and slots that must be precisely stamped to properly fit with the two internal cores — assembly must ensure the cores don’t fall out and the fitting clearance meets spec (checked with a Ø20.05 pin gauge).
The 2.6mm thickness directly affects the magnetic gap during assembly, so it requires 100% inspection at 6 points around the circumference rather than sample checking, needing a dedicated measurement step after plating to account for plating thickness variation.
