Product details

Board-Edge Power Header for Harness Integration

18 Circuits, Dual-Row, Fully Loaded

The header carries 18 positions arranged in two rows with 0.165" (4.20mm) row spacing. Compared to a 16-circuit sibling in the same series, this 18-position version adds two more circuits for applications needing extra power or signal lines without increasing the board footprint beyond the dual-row layout.

Mounting and Mating Details

The mounting flange provides additional mechanical retention to the PCB. Mates with Mini-Fit Jr receptacle housings (series 5557) using the matching crimp terminals (series 5556).
