1.7mm pitch, Low Profile Wire-to-Board Connectors for Power Supplies DF65 Series (UL, C-UL, Listed) Lock structure and operation Socket Latch Header Latches are deflected slightly during mating. Features 1. Enhanced contact reliability and lock structure The unique locking structure reinforces the engagement between the wire side portion and the header. This prevents the wire side from becoming misaligned due to stress from poorly routed wiring. (Fig.1) (Patented) 2. Vertical mating provides superior handling The use of vertical mating style reduces assembly time and maximizes precious board space which gives designers more freedom when designing other components on the PCB. (Fig.2) 3. Highly reliable contact structure The two point contact structure provides optimum Fig.1 reliability, a low mated height of 1.8mm and an effective mating length of 0.35mm. Vertical mating provides superior operability and maximizes board space. 4. Increased cable retention The header is designed to press the terminal lance down during the mating operation this Side view of the PCB Vertical mating type prevents the lance from moving and enhances Vertical mating style allows other parts to be mounted. its strength. (Enhances freedom in designing PCB) 5. High current of MAX 4A (24 AWG) By utilizing highly conductive material for the female terminals and suppressing the contact resistance, the DF65 series can handle a maximum of 4A with 24 AWG wire. The mating face is easy to see, resulting in proper insertion. 6. Solder wicking prevention Molding is done in a way that removes the gap between the contacts and the housing to prevent wicking. Unused, open area Horizontal mating type 7. Prevents Accidental unmating The molded structure is designed to prevent accidental unmating due to poorly routed wiring and harsh loads. 8. UL and C-UL Certified The mating face can be hard to see, which can lead to awkward insertion.
