Dubox 34-Position Dual-Row Receptacle — Board-to-Board Fit
In a production board that gets mated during test and again in the field, this holds up. For a board stack that doesn't see vibration, this is fine; if the assembly gets bounced, you want a locking header.
Housing and Compliance — UL94 V-0, Active Production
The housing is glass-filled polyester rated UL94 V-0 — the highest common flame class for connector bodies inside equipment enclosures. No derating needed for flammability in most industrial or commercial gear.
