HARTING Technology Group

The Han® Ex , an extension of the Han® product line, meets all the preconditions for the implementation of high-quality connectivity solutions in application areas with explosion protection requirements.

Han® Ex – product offering

The product portfolio for the Han® Ex offers complete connector systems approved for Class I Div 2 environments. These connectors handle up to 90V and 16 amps with various hood and housing sizes and pin counts from 3 to 24. The housing‘s alloy was selected so that it can be used in pulverized methane-coal dust atmospheres. Furthermore, they offer IP 65/67 protection class in mated condition. The housing’s blue color indicates that the connector is being used in a potentially hazardous location.

The Han® Ex product offerings come in various termination technologies, including the traditional crimp and screw varieties, along with the patented Han-Quick Lock® technology. This termination allows for time-saving and easy assembly without special tools. The reliable and vibration-proof connection provides maximum safety even in demanding applications.

Now that the connector options for the Class I Div 2 environment has expanded and the size and costs are significantly lower, our customers able to look at the benefits of connectorization vs hardwiring again!
