2 mm Pitch, Direct-To-Circuit Board Connector, DF4 Series
Caution
Product Description
Connector for direct board-to-cable connection with 2-mm pitch. By directly attaching the terminal insertion socket into the circuit board, the header cost can be minimized.
[Features]
・Minimizes header cost: using a dual insertion-removal socket and directly attached connector terminal harness, both circuit boards can have their separate functions used as-is, reducing the required number of headers for a dual terminal socket harness from 2 to 1.
・Small type/multi-pin: a wide range of small types with a number of pins.
・Circuit board mounting height: 4.3 mm (1 crimp attachment array), maximum pin number: 32 (2 crimp attachment arrays).
・Temporary circuit board fastening mechanism: Connector can be temporarily affixed to the circuit board in order to make insertion easier.

Product Usage Precautions
Soldering precautions
- Flow conditions for automatic soldering devices - Solder temperature: 250°C ±5°C, Soldering time: within 3 seconds
- Manual soldering conditions - Soldering iron temperature: 290°C ±10°C, Soldering time: within 2 seconds
- If the cable neighboring the connector area is bent, the cable jacket may break due to solder heat, causing the cable core to be exposed. To prevent this, ensure a large bending radius (refer to diagram)
- After soldering, applying a load to the cable while the cable or connector is still holding heat may cause the jacket holding area to become loose. As such, be sure to return the connector to room temperature after soldering
Do not use solvents such as trichloroethane that may cause cable coating damage. Also avoid heated cleaning when using solvents.
