Contact system and reconnect duty
The 0015249187 is the 18-circuit member of Molex's Mini-Fit BMI 42404 shrouded header line, designed for board-to-board or cable applications. Mating contacts are gold-plated (30.0 µin / 0.76 µm) on a brass square pin — the gold finish supports repeated mate-unmate cycles without contact fretting, suited for field-service or modular assemblies.
Mounting and board retention
Through-hole right-angle mounting with board locks holds the header in place during wave solder and resists shear from cable strain. The 4-wall shrouded housing with latch holder prevents mis-mating and secures the cable plug. Blind-mating geometry eases alignment in enclosed or rack-mounted assemblies where the connector pair is not visible during engagement.
