Product Description

MDF6 Series 3.5mm Pitch Miniature Double Row Connector for Secondary Power

The MDF6 Series is a miniature, space-saving double-row connector featuring a 3.5mm pitch. Designed for secondary power applications, it offers a robust 7A current capacity with 16 AWG wire and incorporates a box-type, polarized header to prevent mis-insertions and resist twisting. An internal latch mechanism ensures a secure and stable connection, protecting against accidental un-matings.
