Battery Block Header — 3-Position, 2.00 mm Pitch
It's designed for low-voltage battery pack interconnects where a compact, keyed push-pull mate is needed. The single-row layout and 2 A per circuit rating suit it for cell-balancing lines, battery management system (BMS) signal paths, or low-power auxiliary connections inside a battery enclosure. The black thermoplastic insulation carries a -20°C to 80°C operating range, which covers typical consumer and light industrial battery compartments.
The 2.00 mm pitch is the dimension that locks the board layout — it's tighter than the common 2.54 mm (0.100") header pitch, so the PCB footprint is smaller and the routing density between pads is higher.
