Intrinsically-safe connectors for potentially explosive atmospheres
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 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. 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.
