2.0mm Dual-Row 20-Pin IDC Female PCB Connector for Signal & Power Wire Harness
Product Description
This 2.0 mm dual-row 20-pin IDC female connector is designed for reliable electrical connection between PCB and wire harness in compact electronic equipment. The connector uses precision stamped terminals with gold-plated contact areas to ensure low contact resistance and stable signal transmission for both power and signal lines.
The blue UL94V-0 thermoplastic housing provides high mechanical strength and heat resistance for automated soldering processes. Through-hole solder tails offer robust retention on the PCB, making it suitable for vibration-prone applications such as automotive control units or industrial controllers. With 20 contacts on a fine 2.00 mm pitch, the connector achieves high-density routing while maintaining adequate creepage and clearance distances.
This connector mates with matching IDC or crimp wire harness assemblies, supporting mixed power and signal transmission in one compact interface. OEM/ODM customization is available for pitch-compatible layouts, plating thickness, keying options, and special locking features to fit your specific board and cable design.

Any compact PCB that requires a 2.0 mm multi-pin signal and low-power connector for wire-to-board transmission
Precautions
Confirm PCB footprint, hole diameter and pitch match the connector drawing before layout.
Keep maximum current within the recommended rating and consider derating for high ambient temperature.
Avoid excessive bending or pulling of the mated cable; provide strain relief in the harness design.
Follow proper wave or hand-soldering profiles to prevent housing deformation and maintain terminal coplanarity.
For outdoor or high-humidity environments, consider conformal coating or sealing to enhance corrosion resistance.
When using for high-speed signal lines, keep trace impedance controlled and minimize stubs around the connector.
