RoHS compatibleTough Contact Advanced


  • 2.5 mm wide ultra-slim two-piece connectors
    The ultra-compact and slim body contributes to further miniaturization and functionality enhancement of target equipment.
    <Compared with our existing model (F4S, 40 contacts, when mated)>
    Width: 30% down, Footprint: 30% down


  • "TOUGH CONTACT ADVANCED" structure adopted to ensure high resistance to various environments in spite of the ultra-slim and low profile body


    • Bellows contact construction improved the ability to withstand twisting and increased resistance to shock of dropping
      “High-precision metal processing”, which is one of our core technologies, provides the contact with adequate flexibility and thereby high impact resistance while achieving the 0.8 mm ultra-low profile.

    • Anti-solder-rise efficiency increased due to Ni barrier
      An area where the nickel-plated layer is exposed has been secured.
      This area prevents solder rise, which conventional ultra-lowprofile connectors are prone to.

    • The V-notch and the double contact structure ensures high-level contact reliability.
      By making contact with the edges and thus increasing the contact pressure, this product can eliminate flux and other foreign matters more effectively.
      In combination with the double contact structure, high-level contact reliability can be ensured.

    • Improved resistance to corrosion by gas, etc., due to porosity treatment
      This treatment consists of coating surface with a very thin film to seal pinholes in the gold plating. We have developed this porosity treatment technology, which ensures the same contact reliability for thin gold plating as that of thick gold plating.



  • The simple lock structure gives tactile feedback that ensures a superior mating/unmating operation feel.

    *The connector gives the tactile feedback when inserted, allowing reliable mating.

  • Mated heights of 0.8 and 1.0mm are available for same foot pattern.
  • Connectors for inspection available.


Recommended for board-to-FPC connections of mobile equipment, such as cellular phones, smart phones, notebook PCs, and portable music players
