Kona Connectors

8.50mm pitch High-Reliability Connectors

Kona expands the Harwin High-Reliability portfolio into new levels of current – 60A per contact. Designed to withstand testing environments and conditions. Currently offered in 2, 3 or 4 single row configuration, for vertical cable-to-board or cable-to-cable. Vibration and shock resistant, compact power future-proofed.

About Kona

  • 60A max per contact
  • 6-finger contact design to maintain electrical contact through high vibration and shock
  • Beryllium Copper contact for improved temperature range: -65°C to +150°C
  • 8.5mm pitch achieves up to 3,000V without flashover
  • Individually shrouded contacts with a recessed design (avoids accidental touch contact)
  • Thumbscrew mate-before-lock fixings for ease of use
  • Metal backshells for cable, panel and PCB mounted connectors provide EMI/RFI shielding

Other useful features include reverse fix screws, polarization, and identification of the #1 position. Harwin provides CAD Models and Test Reports to assist with your design activities.

Heart of the Connector

A compact yet powerful 6-fingered male Beryllium Copper contact, turned in Harwin’s state-of-the art HQ facility. Capable of 60A per contact, with minimum PCB footprint and height above board. Maintaining the high quaility standard set by other High-Reliability connectors in the range. Capable of power connections for demanding applications on land, sea and air.
