R35K (0.35 mm pitch)

The ultra-small ( width 1.3 mm ) , robust yet high mating force connector that can energize 3 A.

Features

  • Slim: width 1.3 mm

  • Low profile construction: mated height 0.6 mm

  • “TOUGH CONTACT” construction withstands tough environments despite being slim and low profile.

  • Double contact with a simple lock structure made this connector realize low profile, make a good clicking feel and high removal force.

Applications

  • Wearable devices, hearable devices
    (Battery, Side Switches, various sensor module connection)
