HRS DF20A 20DS 1C 1 mm pitch low profile double rows board to cable connector for electronic devices
DF20 Series: 1 mm Pitch Double Rows Low Profile Board-to-Cable Connectors
The DF20 Series offers compact and reliable board-to-cable connection solutions with a 1 mm contact pitch. These connectors are designed for low-profile applications, featuring narrower external dimensions and metal fittings that enable end-to-end mounting. They are suitable for automated equipment board placement and support AWG #28, #30, and #32 conductors, making them ideal for a range of portable and small electronic devices.
