Han-Ex® connectors are designed to meet the intrinsic safety requirements for ignition protection in explosion-hazard areas zoned 1 and 2. In intrinsically safe circuits, a limit is set to energy so that even a spark would not ignite an explosive environment.

With the Han-Ex® series, HARTING offers a comprehensive and well-matched connection systems consisting of hoods/housings, inserts and cable glands.

• Introduction
  • The Han-Ex® connectors are available in large number of variants. 
  • Hoods and housings are made from an alloy that can safely be used in a methane-coal atmosphere.
  • In addition, hoods and housings offer protection IP65 (in mated position).
  • Furthermore, the hood’s/housing’s blue colour indicates that an intrinsically safe circuit is present.
  • The inserts compatible with Han-Ex® allow for high-density contact arrangements, meeting the standards of the category intrinsically safe even in the tightest of spaces.
  • Finally, a Han-Ex® connector is always part of a comprehensive supply system for devices in the field, including current transfers between Ex and Non-ex areas.
