Features
1. Reduces the cost of the headers.
Extractable socket and board-in connector provided with the dual-
sided harness eliminate one of the two headers required for a dual-
sided socket harness, with the board separating function remaining
unchanged.
2. Space-saving

The rated current varies depending on the size of wires connected to the connector.
Includes temperature rise when power is on.
"Storage" refers to a long period of storage without use of the product before being mounted on a board.
The operating temperature and humidity ranges apply to when the product (power off) is mounted on a board.
The above standards are typical for the DF2 series. The formal standards are stated in the delivery specifications.

Notes on use
1. Recommended soldering
conditions
s
Flow conditions for automatic soldering device: Solder temperature: 250±5°C, soldering
time: Within 3 seconds
s
Manual soldering conditions: Solder temperature: 290
±10°C,
soldering time: Within 3
seconds
s
If a load is applied to the cables while the connectors and cables are hot after soldering,
the coating clamps tend to be loosened. Wait until the connectors cool off to room
temperature after soldering.
See "GUIDE TO HIROSE NYLON CONNECTORS."
Do not use a solvent such as trichloroethane that damages the cable coating.
Also, do not use heated solvent for cleaning.
