The Molex 431600102 is the 2-position member of the Sabre 43160 series, a through-hole header with male blades designed for wire-to-board power interconnects in harness assemblies.
The 600 V rating at 7.50 mm pitch supports industrial-grade isolation; the tin plating (60.0 µin on the contact surface) is suited for moderate mating-cycle applications — gold would be needed for frequent reconnect duty, but tin holds up well in a permanent or semi-permanent harness install.
The 431600102 shares the same 7.50 mm pitch, 18 A per position, 600 V rating, tin plating, and locking ramp as the 431600105 — the only difference is position count.
