HARTING Han Ex, Class 1 Div II Connector Series

The product portfolio for the Han® Ex offers complete connector systems able to supply up to 90V and 16 amps with various hood and housing sizes and pin counts from 3 up to 24. The housings’ alloy was selected so that it can be used in pulverized methane-coal dust atmospheres. Furthermore, they offer an IP 65/67 protection class in the 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 choice of connectors has increased and the size and cost is significantly lower, it allows our customers to look at the benefits of connectorization vs hardwiring again!
