With free heights from 1.8–2.5 mm, working ranges from 0.85–2.4 mm, and operating temperature of -40 to +85°C, FCN-118X Series is suited for smartphones, tablet PCs, and wearable devices. Side-wing construction prevents form deformation by outer force in handling, while stop point prevents further displacement if excessive contact force is applied. In addition to providing frame grounding, some grounding springs can also function as power contact between printed circuit boards.
