What it is
The Molex 1720420502 is the 5-circuit member of the Super Sabre 172042 series — a single-row power header with male blade terminations, 0.295 in (7.50 mm) pitch, and through-hole solder mounting. Silver-over-copper contacts are plated 100 µin (2.54 µm) on the mating face, rated 30 A per circuit at up to 600 V. The housing is black glass-filled LCP, the locking ramp mechanically secures the mated pair, and the board-lock feature plus finger-proof shrouding protect the assembly during field handling and vibration exposure.
What those ratings mean
Fitting it into the BOM
Five positions at 7.50 mm pitch means a board footprint roughly 30 mm wide — check your clearance between adjacent components before committing. The through-hole solder footprint is the standard industrial power-header land pattern; no SMT reflow profile needed. The board-lock legs anchor it without a separate screw or adhesive — a real advantage when the enclosure sees thermal cycling. The finger-proof shrouding satisfies the touch-safety requirement in exposed panel sections without adding a separate guard. Confirm the mating half carries the matching locking ramp feature; if it doesn't, the ramp won't engage and the connection relies entirely on contact normal force.
