Product Description
DF65 Series 1.7mm Pitch Low Profile Wire-to-Board Connectors for Power Supplies
The DF65 Series connectors are designed for power supply applications, offering a low profile and 1.7mm pitch for space-saving PCB designs. They feature enhanced contact reliability, a secure lock structure to prevent wire misalignment, and vertical mating for improved handling and assembly time. The two-point contact structure ensures high reliability with a low mated height of 1.8mm. These connectors are capable of handling high currents up to 4A (24 AWG) and incorporate features to prevent solder wicking and accidental unmating. They are UL and C-UL certified.
