TTI is now stocking CHD (Circular Heavy Duty) connectors from Amphenol Industrial. The robust, high-performance CHD14 series is designed for demanding commercial and off- road vehicle applications like EV battery pack, inverter and power distribution systems where electrical connections must be secure and resistant to harsh environmental conditions.
Rated at 1500VDC for currents up to 500A the connectors have an operational temperature range of -40 to 125°C and at least 50
mating cycles. Available in one and two-pin options, the unmated socket is IP67 rated. The aluminium housing and silver-plated copper alloy contacts are highly resistant to corrosion, providing a long service life. When mated, the interconnect is sealed to IP6K9K.
TTI Europe’s industry marketing director transportation, Dermot Byrne, said: “High- voltage DC powertrain applications, such as those used in electric vehicle battery pack, inverter and power distribution unit systems, require connectors specifically designed for high-voltage and high- current DC power transmission.”
