Connectors meet intrinsic safety requirements for use in potentially explosive areas

to overview

11.07.2014 | The new Han® Ex range of connectors from HARTING meet all the requirements for the implementation of high-quality connectivity solutions in application areas with explosion protection requirements. This includes applications in mining and the chemical and process automation industries.

The connectors are designed to meet the intrinsic safety requirements for ignition protection class in explosion hazard areas classed as 1 and 2. In intrinsically safe circuits, energy is limited in such a manner that even a potential spark cannot ignite an explosive environment.

The Han® Ex product 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. They also offer ignition protection class 65 in the mated condition.

The housing’s blue colour indicates that an intrinsically safe circuit is present. The contact inserts provide a high number of pins and meet the standards of the ignition protection class even in the tightest of spaces.

The termination technology used in the Han® Ex is based on HARTING’s patented Han-Quick Lock® technology. This allows time-saving and easy assembly without the need for special tools, and provides a reliable and vibration-proof contact for maximum safety in the most demanding applications. HARTING’s proven crimp technology can also be selected as the termination method, allowing the connection of wires with cross-sections from 0.14 to 2.5 mm2.
