10-Position Shrouded Header with Locking Ramp
The 4-794631-0: The 3.00mm pitch and 0.118" row spacing set the board footprint — a standard spacing that matches the Micro MATE-N-LOK receptacle family. In a vibration environment — say, an industrial cabinet or a vehicle interior — that latch keeps the pair mated without relying on friction alone. You should hear it click. For a connector that sees quarterly field-service disconnects, the gold interface resists fretting corrosion and maintains contact resistance over decades of service.
Termination Options and Board Fit
The header accepts both press-fit and solder termination through the same through-hole footprint. Press-fit is useful for backplane or high-reliability assemblies where solder reflow is undesirable; the compliant pin compresses into the plated through-hole without wicking solder. Solder termination is the conventional route for wave or hand-soldering. The contact length after the board is 0.125" (3.18mm) — enough to protrude through a standard 1.6mm PCB and accept a solder fillet. The insulation height of 0.364" (9.25mm) above the board surface leaves clearance for the mating receptacle and wire exit. In a tight enclosure, check the z-height budget against the mated stack height of the receptacle.
In the Micro MATE-N-LOK system, typical per-contact current is 5A with 20 AWG wire at a 30°C temperature rise. Derate above 85°C ambient per the series derating curve. Voltage rating is 250V, suitable for signal and low-power distribution within that ceiling. The header is rated for general-purpose applications; not intended for high-voltage or mains isolation without additional clearance checks.
