Temporary but safe disconnection of power is critical in many
industries. To meet this need Hawke International have introduced a new series of EExd connectors that are
ATEX approved, easy to use and exceptionally robust. They permit the safe and speedy service, repair and
replacement of key plant items or provide quick connection to temporary equipment. Their application is
beneficial in capital-intensive processes where minimum downtime is essential.
The new connectors are ideal for zones 1 and 2 explosive environments commonly found in oil and gas
exploration, production and process plants. However, their features also offer benefits in explosive dust
environments, or in harsh and hostile non-explosive applications.
In compliance with the ATEX Directive (94/9/EC), the new design retains many of the best features of
Hawke's previous connector range, but in addition adds innovations based on user feedback. The heavy duty
maintenance free stainless steel body construction is retained, as is the well accepted Acme mating thread
for speed of use and freedom from thread binding or galling.
Hawke's new ATEX connector is not dependent on tagging to identify the correct mating halves; this
removes the theoretical possibility of accidentally connecting adjacent circuits. Pin or socket inserts may
be located in either half of the connector and locked into one of five individually keyed positions. This
prevents accidental mis-coupling and gives up to ten unique connector combinations.
Another Hawke innovation enables terminations to fully comply with the strict heat cycling and explosive
pressure tests imposed by the ATEX Directive. Using technology already proven in their ICG barrier cable
glands, Hawke have included their revolutionary removable compound chamber concept into the connector
design. This feature enables quick and easy inspection of the flameproof barrier seal, saving time and
resources - important benefits given the ATEX demands for frequent inspection.
The connector is supplied as a piece of approved apparatus. It is therefore safe for immediate
installation into other certified 'EExd Flameproof' or 'EExe Increased Safety' equipment without having to
seek further third party approval.
The connectors are available in many sizes and configurations, varying from M16 to M63 and may have from
3 to 60 contacts. Each is deluge rated and offers IP66 and IP67 ingress protection. The ATEX certification
enables these connectors to be safely used in dust environments, zones 21 and 22 as well as zones 1 and 2
gas environments. The connectors are tested and certified for a safe operating temperature range of -40 to
+100 degrees C. The standard temperature classification of T6 at 40 degrees C ambient temperature is
supplemented by optional higher ambient temperatures and T5 classification.
