With a compact layout and stable connection, it is suitable for the miniaturization needs of electronic devices.

introduction：

The 1.27mm spacing 8-pin dual row direct insertion female connector is a basic interconnect device used for signal and low-power power transmission between PCB boards. Its core features are compact, stable, and highly adaptable; It adopts a precise 1.27mm pin spacing and a dual row 8-pin (4-pin per row) layout, which can achieve multi-channel transmission in limited PCB space, saving about 36.5% space compared to a 2.0mm spacing. It is suitable for compact scenarios such as smart wearables and small modules. It is installed as a through-hole direct insertion type, with high mechanical strength and anti vibration impact after pin insertion board soldering. It is also convenient for manual soldering and maintenance, taking into account both prototype production and mass production; In terms of material, the shell is made of flame-retardant materials such as PA66 and PBT, which can withstand high welding temperatures of 260 ℃. The terminals are made of copper alloy substrate plated with tin or gold, with low contact resistance and oxidation resistance, ensuring long-term conductivity stability. It also has a plug-in life of ≥ 25 times and can effectively prevent loose connections. It is widely used in consumer electronics, industrial control and other fields.
