The Molex 0431600105 is a 5-circuit male header from the Sabre 43160 series, a power interconnect family built around a 7.50 mm pitch. The black glass-filled PA46 insulation handles the -40°C to 75°C operating range typical of industrial cabinet and power distribution environments.
Each blade has enough cross-section to carry bus-level current — this is a power rail connector, not a signal header. The 60.0 µ" tin contact finish is thicker than standard tin flash, which matters for corrosion resistance in humid or mildly corrosive environments, but tin is a low-cycle finish: expect a few hundred mating cycles, not thousands.
Locking Ramp and Mating Half
No secondary lock or TPA is built into the header itself — the ramp is the sole retention, and it's sufficient for the vibration levels typical of industrial control panels and power supplies.
