What this header does and where it fits
The 4-794638-6: This is a 16-position, dual-row, surface-mount header from the Micro MATE-N-LOK series, designed for board-to-wire connections. Its 3.00mm pitch and 3.00mm row spacing give you a compact but routable footprint for signal and low-power distribution on a PCB. The locking ramp fastening provides a positive mechanical latch against the mating receptacle, which matters when the cable assembly sees vibration or accidental tugging. The header is fully shrouded on all four walls, so the pins are protected during handling and mating. Gold plating on the mating contacts (30.0µin thick) handles repeated connect-disconnect cycles without oxidation buildup, while the solder tails have a 100.0µin tin finish for reliable soldering to the PCB.
Mating and termination details
This header mates with Micro MATE-N-LOK receptacle housings that accept crimp terminals. The locking ramp engages with the corresponding latch on the receptacle side — you should hear it click when fully seated. The SMD solder tails are designed for reflow assembly; the solder retention feature helps hold the part in place during soldering. The square male pins accept female crimp terminals from the same series; the contact material is brass. Current rating varies by wire gauge used in the mating half, so size your wire for the load.
