What it is
The Molex 431600105 is the 5-circuit member of the Sabre 43160 series — a single-row male-blade PCB header with a 0.295" (7.50 mm) pitch and through-hole solder termination. The contacts are brass with 60.0 µin (1.52 µm) tin plating. The body is black glass-filled Polyamide (PA46, Nylon 4/6), the locking ramp provides positive retention during insertion, and the insulator is rated for operation from −40 °C to 75 °C.
What the ratings mean
At 18 A per circuit the Sabre 43160 sits above typical power-header ratings at comparable pitch — the tin plating (60.0 µin) supports that current but is graded for permanent installation rather than high-cycle reconnection, so confirm the mating half's plating spec if your application involves frequent plug cycles. The 600 V rating covers industrial three-phase and high-voltage DC bus positions at this pitch; the −40 °C to 75 °C operating window is appropriate for enclosed-panel use but leaves thermal headroom above 75 °C unused — for unventilated or elevated-ambient enclosures a cooler-running alternative may be warranted.
Where it's used
The Sabre 43160 series is deployed as a board-to-wire power interconnect in industrial automation enclosures and motor-drive panels. The 5-position count maps to low-density power rails, contactor coil drives, or three-phase + neutral + earth bus-takeoff points where the 600 V rating and the locking ramp retention are both needed. Bulk packaging is standard for panel-builder purchasing lanes.
