Board to Board Connectors

5861 Series

Robust type Metal tab Power

The 5861 Series are space-saving Board to Board Connectors featuring a fine pitch of 0.35mm, stacking height of 0.6mm (between boards) and a width of 1.95mm. With the metals covering both ends, the connector, with narrow pitches and low profile though, realizes the structurally high robustness and smooth guiding function for mating to prevent breakage of the insulator housing and contact caused by misaligned mating. The metals at both ends of which rated current is 5.0A/metal tab enable to carry a large current.

0.35mm Pitch

Typical Applications

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

  • High robustness and structure for smooth mating with top face covered by metals.
  • Space-saving connector with a fine pitch of 0.35mm, stacking height of 0.6mm, and width of 1.95mm.
  • Anchoring metal tabs are available for power connection with a rated current of 5.0A(/metal tab).
  • A pinching structure (two-point contact design), which is highly resistant to vibration and drop shocks, has been adopted for the contact structure. Furthermore, the plug contacts have an original structure featuring a wiping effect which eliminates foreign matter with concentrated load, thus realizing high contact reliability.
