DF33 Series 3.3 mm Contact Pitch Connectors for Internal Power Supplies

The DF33 Series connectors are designed for internal power supply applications, offering a 3.3 mm contact pitch. Key features include a 5 A maximum current rating with #20 AWG conductors, a reliable complete locking function to prevent accidental disconnection, and prevention of incorrect connections through distinct mating configurations and built-in guide keys for correct board placement. These connectors support encapsulation up to 10 mm and are designed to prevent short circuits between adjacent contacts with fully enclosed insulators. Enhanced retention force for crimped contacts and visual confirmation of insertion are also provided.
