521743-1 is a natural nylon connector housing manufactured by TE Connectivity. The housing is produced with natural nylon resin, which may display color variations ranging from white to green or yellow due to the hygroscopic nature of the material and the presence of copper ion heat stabilizers. These color variations do not affect the Form, Fit, and Function of the product as validated by the resin supplier and TE Connectivity's testing. The product undergoes validation testing including visual examination, contact retention force, insulation resistance, dielectric withstanding voltage, thermal cycling, and humidity testing. This connector housing is suitable for household appliance and white goods applications where high safety performance materials are required.
