Stopping plug maintains enclosure sealing

A new push-in EExe stopping plug for harsh environments, the ExPress from Hawke International, has received Baseefa accreditation.

A new push-in EExe stopping plug for harsh environments, the ExPress from Hawke International, has received Baseefa accreditation.

The ATEX compliant plug is suitable for enclosure seals in Zones 1, 2, 21 and 22 hazardous areas and meets IP66 ingress protection requirements.

The plugs are certified for operation in temperatures from -40 to +80C.

The ExPress plug is easy to install in all types of instrument enclosures.

No special tools are required and they eliminate locknuts and serrated washers that can be difficult to install in confined spaces.

Manual pressure only is sufficient to engage the plug and ensure complete sealing.

The new plug complements Hawke's EZE hazardous area enclosure, a radical clam-shell design.

Users in control and instrumentation will find that using these products together offer greater safety and productivity.

Hawke will offer the ExPress plug as a component to other manufacturers such as OEMs, instrumentation suppliers and control panel builders seeking high integrity seals.

The introduction of the ExPress stopping plug coincides with the extension of the EZE enclosure range with the introduction of the EZE 62.

This enclosure has a face area of 624 x 319mm and a depth of 183mm to accommodate 60 M20 cable entries and a maximum of 190 WDU 2.5 terminals.

There are three models in the EZE range with one, two or three factory-fitted gland plates.

These can remain blank for on-site drilling or be predrilled and plugged to the customer's specification.

Inside the cabinet, removable brackets hold the terminals, DIN rails, or instrumentation away from the back plate to make assembly and under wiring easy.

For access, the single-piece lid is hinged to allow vertical opening.

This gives the technician full access from the front and side, with the open lid also acting as a temporary weather-shield while the enclosure is being wired, inspected or modified.

Hawke's Mike Connelly explained: "Unused cable entries in the gland plates can now be sealed using the EExe certified ExPress plug, which eliminates the need for special tools, but remains completely tamperproof in that it can only be removed from inside the enclosure".

"The push-in plugs allow users to modify wiring more easily and seal any unused entries with complete confidence".
