What this header is
The Molex 431600304 is the 4-circuit member of the Sabre 43160 series — a single-row, through-hole PCB header built around a 0.295 in (7.50 mm) pitch. The locking ramp on the housing body differentiates it from a plain friction-fit blade header and is the detail that governs vibration retention in harness-level interconnects.
Key ratings and what they mean
Where the Sabre class is used
Sabre 43160 headers sit in wire-to-board and board-to-board power interconnects inside industrial automation equipment, motor control cabinets, and commercial appliances. The 7.50 mm pitch provides generous spacing between circuits for high-current paths while keeping the board footprint manageable compared to fully discrete wired terminals.
