EMI back-shells for Harwin mini power connector

“These back-shells will stop undesirable EMI leaking out from the connector-cable meeting into the encompassing system,” in line with the corporate. “The 2-part building of the Kona backshells permits engineers to up-grade their current cable assemblies with 360° EMC shielding.”

Kona connectors are available 2, 3 and 4 contact variations with an 8.5mm pitch, and might carry as much as 60A per contact. In addition to cable finish variations, board and panel-mount variations can be found – the latter permitting full shielding with steel enclosures.

Cable finish shell sorts are designed to accommodate versatile steel braiding (left), and are equipped with tie-bands to connect the braiding to the shell, and the back-shells set up with easy instruments.

Development is 6061 aluminium aerospace alloy, nickel-plated for corrosion safety.

Use is foreseen in area, unmanned aerial autos, robotics and electrical autos.

“In conditions the place energy connectors are located close to a dc-dc converter, corresponding to in car charging infrastructure, the excessive currents being transported could cause distortion waves that may place stress on the converter,” stated Harwin v-p of merchandise Ryan Sensible. “By having a back-shell shielding choice we’ve added an providing that may handle issues of this type.”

Kona connectors have 2mΩmax contact resistance and are rated for 250 mating cycles and 1.5k dc (or peak ac) at sea stage. Max voltage is 3kVac (1minute), or 500Vac at 70,000ft (21km/44mbar).

Harwin merchandise are manufactured within the firm’s facility in Portsmouth, England.
