Easy-to-use certified connectors for hazardous firedamp environments

26 August 2010

A range of explosion-proof connectors that simplifies the commissioning and decommissioning of electrical equipment installed in hazardous firedamp environments, including underground mines is now available from Cooper Crouse Hinds.

The new eXLink mining connector enables the commissioning and decommissioning of a wide range of electrical equipment in underground mines, without having to use any special tools and without having to isolate, then disconnect the equipment. This means the installation, maintenance and repair of any electrical apparatus in firedamp areas can be carried out in a simple, safe but cost-effective manner.

eXLink is designed with armoured cables, which are certified for use in hazardous firedamp areas. This means that any electrical device with power consumption up to 16A – light fittings, alarms, sensors, motors and drives – can simply be plugged in and out using the connector.

Light fittings, for example, which are connected using eXLink can be serviced or replaced at any time without having to disconnect the complete lighting circuit. Actuators and sensors that use eXLink connectors can now be replaced quickly and safely at all times. Similarly, components on large machines can be replaced much faster and more safely, with minimal effort.

By using the eXLink 6+1 connector, current consumers with 3 phases up to 16A, PE and 2-wire control lead can be connected by using just a small plug.

These Ex-de protected plugs and couplers are easy to handle and compact. The contact sockets are fitted with well-proven CEAG lamellar contacts made from punched, specially treated copper beryllium tape, which, due to a large number of contact points, ensures proper electrical connection at all times. An Ex-d housing and the plug pins ensure reliable protection against firedamp in hazardous areas, both during connection and disconnection of the connector. As with other eXLink products, the plugs and sockets can be coded.

Depending on the application, the customer can choose between 4-pole plus PE (eXLink 4+1) or 6-pole plus PE (eXLink 6+1) versions. The enclosures are available in nickel-plated brass or stainless steel.
