1.25-3P Double-Head Connection Cables

Product Overview

The 1.25-3P double-head connection cable is an electronic interconnect cable primarily used for connecting circuit boards. The 1.25mm pitch connector with 3P (3-pin) configuration comes in single-head and double-head types, with cable lengths typically ranging from 15cm to 50cm. This compact connector design saves approximately 45% of printed circuit board space compared to 2.00mm pitch products.
