“This addition makes it possible to bring male and female cables together for the first time in a cable-to-cable arrangement, whereas previously we were only offering Kona in cable-to-board options,” the company told Electronics Weekly.
“The additions are suitable for use with both standard cable connection and made-to-order cable assemblies,” it said. “Engineers can select housings with or without panel mount-fixings – compatible with the thumbscrew fixings on the female. Reverse-fix thumbscrews compatible with female reverse-fix panel mount fixings are also available.”
All fixings are designed to mate-before-lock.
Initially launched in November 2020, Kona connectors use six-fingered contacts to maintain electrical contact through vibration and shock, with beryllium copper allowing operation across -65 to +150°C.
Working voltage is 1,500V dc or peak ac, and pin pitch is 8.5mm to handle 3kV without flashover (60s test, sea-level – max at 21km altitude (70,000ft 44mbar) is 500Vac for 1 minute). Insulation Resistance is 10GΩ min (1kV). Maximum contact resistance is 2mΩ, and the quad contact version can handle a total of 240A.
To reduce the chance of accidental touch, contacts are individually shrouded and recessed.
The company sees them being used in space, electric vehicles, unmanned aeroplanes and robotics.
