The 3-794638-4: This 4-position, 2-row header uses a 3.00mm pitch on both rows, setting the board footprint for the mating wire receptacle. The shrouded 4-wall housing guides the plug during blind mating and prevents contact damage from off-angle insertion. In a vibration-prone environment—like an industrial cabinet or automotive interior—this latch keeps the pair mated without relying on friction alone.

Product details
Frequently asked questions
What is the mating connector for 3-794638-4?
This header mates with a Micro MATE-N-LOK receptacle housing (e.g., 3-794637-x series) that accepts crimp terminals.
What is the recommended PCB layout for 3-794638-4?
The footprint uses a 3.00mm pitch between positions and 3.00mm row spacing. The SMD pads should match the solder tail dimensions; the shrouded housing requires a keep-out zone around the 9.25mm insulation height for clearance above the board. Refer to the product drawing for exact pad geometry and stencil aperture.
