Meeting the requirements for the implementation of high-quality connectivity solutions in application areas with explosion protection requirements, HARTING has introduced the Han Ex range of connectors. These are suited for use in applications in mining and the chemical and process automation industries.

These connectors meet the intrinsic safety requirements for ignition protection class in explosion hazard areas classed as 1 and 2. Energy is limited, even in intrinsically safe circuits, so that even a potential spark cannot ignite an explosive environment. The housing's blue colour indicates that an intrinsically safe circuit is present.

Providing ignition protection class 65 in the mated condition, the Han Ex portfolio portfolio offers complete connector systems consisting of housings and inserts, including housings made from an alloy that can be used in pulverised methane-coal dust atmospheres. The contact inserts provide a high number of pins and meet the standards of the ignition protection class even in the tightest of spaces.

With termination based on HARTING's patented Han-Quick Lock technology, the Han Ex connectors enable time-saving and easy assembly without the need for special tools. They also provide a reliable and vibration-proof contact for maximum safety in the most demanding applications.

HARTING also allows crimp technology to be selected as the termination method, allowing the connection of wires with cross-sections of 0.14-2.5mm2.
