Intrinsically-safe connectors for hydrogen applications (Han-Ex®)
- 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.
- Han-Ex® connectors are designed especially for the named explosion protection method.
- The intrinsic safety protection technique is based on the limitation of energy supply, thus ensuring a safe operation of electrical equipment in hazardous areas.
- The limitations may relate to current, voltage, capacitivity and/ or inductivity.
- 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.
Connectors guide with all variants
- Introduction
- The Han-Ex® connectors are available in large number of variants. For details see Han-Ex® product portfolio guide – click here.
- 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.
