The BM57 is a flexi-to-PCB connector for 5 A power applications and 300 mA signal applications. With 0.3 mm pitch, 0.6 mm stacking height, and a width of only 1.9 mm, it is the perfect design solution for space-critical applications such as within handheld devices, laptops, and wearables. Guidance ribs on the connector allow for smooth mating, and an armoured design significantly mitigates damage from misalignments. For peel resistance, there are solder retention tabs at each power contact with measures to prevent solder wicking at the contact area.
