What This 5-Pin Header Does on Your Board
The 0026644050: This is a Molex KK396 header, 5 circuits on a 3.96mm pitch, single row, vertical through-hole. It mates with a KK396 crimp receptacle housing to make a wire-to-board connection.
Friction Lock and Shrouding – Fit and Retention
The 1-wall shroud guides the receptacle into position and protects the pins during unmated handling. A board guide aligns the header during insertion, reducing pin damage on automated assembly lines. The 0.446" (11.33mm) insulation height leaves clearance for the mating receptacle body — check your enclosure z-height if the connector sits near a cover.
Where This Header Gets Used
The brass pins with 60µin tin finish carry signal or moderate power; typical per-contact current is 5A, limited by the tin interface temperature rise.
