HRS DF4-9P-2C
DF4 Series 2mm Pitch Connector Directly Mounted on Board
The DF4 Series is a 2mm pitch connector designed for direct mounting on PCBs. It offers cost savings by eliminating one header in typical board-to-board configurations, miniature size with a broad range of contact options (up to 32 contacts), and a board pre-fixed mechanism for easy assembly. Applications include PCs and small business equipment.

Precautions
Soldering Condition: Manual soldering: 29010C for 2 seconds. Recommended Flow: 250C for 3 seconds. Ensure adequate bending radius for cables near the connector to prevent jacket breakage. Avoid applying stress to the cable while the connector and cable are still hot after soldering.
Cleaning Condition: Refer to Nylon Connector Use Handbook. Avoid solvents like trichloroethylene and heat cleaning.
Connection Condition: Refer to the Nylon Connector Use Handbook.
