“Built with high vibration resistance, the connectors’ rib design provides a secure fit when mating the plug and receptacle. When mated correctly, there is a clear tactile click,” said the company, adding: “The series passed the 2,000 Hz vibration test [and] it is a UL/C-UL standard-certified product.”

Called KW30, the contacts have two-point contact, and effective mating length of 0.7mm, and the “plug crimp contact has a box shape that does not easily get caught or deformed”, it continued.


Rating is 100V and -55 to +105°C.


Contact counts are:

  • 2 – 15 for 800mA 32AWG contact types
  • 2 – 15 for 1A 28 – 30AWG contact types
  • 2 only for 3A 28AWG contact types

Contact resistance is 30mΩ and estimated life is 30 mating cycles.

Use is foreseen in office equipment, medical devices, home appliances and industrial robots. I

Established in 1937, Hirose is a Japanese manufacturer with European headquarters in Amsterdam and branches in Germany, UK, France and Italy.

The company has been busy recently, announcing automotive flexi-to-board connectors only two weeks ago.
