Board-to-wire header for 6.35mm pitch harnesses
The 1318699-3 uses 3.00µin gold plating versus the 350737-4's 30.0µin gold — a tenfold difference in plating thickness that translates to significantly fewer mating cycles before contact wear becomes a concern. For applications requiring frequent disconnect, the 350737-4 is the more durable option.
Mating receptacle and termination
The 0.250" (6.35mm) pitch receptacle contacts are available in both tin and gold plating — match the plating grade to the header for optimal corrosion resistance and contact resistance over the service life.
