Board to Board Connectors

5857 Series

Robust type Metal tab Power

The 5857 Series are Board to Board Connectors with a fine pitch of 0.35mm. These products feature a low stacking height of 0.7mm and a space-saving design with a width of 1.9mm. With the fine-pitch and low-profile features, the connector achieves high robustness by covering both ends with metals, which prevents the connector from damage caused by misalignments. The new product has a unique contact structure like the Kyocera's existing products, attaining high contact reliability against vibrations or drops.

0.35mm Pitch

Typical Applications

Smartphone, Tablet PCs / Notebook PCs, Wearable Devices, DSCs / DVCs, Audio Players etc.
