Ex-protected plug connections

17 September 2008

Cooper Crouse-Hinds has extended its eXLink connector series for hazardous areas by a series of 6+1 pole connectors. The connectors, plugs, receptacles, inlets and elbows of the series eXLink are designed in the type of protection Ex-d. They are extremely small and can be used in the instrumentation technology for all active devices and sensors.

The contact pins feature CEAG contacts made of treated copper-beryllium tape. A large number of contact points guarantee a continuous electrical contact. A coupling ring integrated in the plug enclosure guarantees the mechanical strength of the connection. The user can choose between cold impact resistant moulded plastic, nickel-plated brass or stainless steel versions.

An Ex-d compartment round the connection pins ensures a reliable explosion protection to meet Zones 1,2, 21 and 22 requirements during the connection or disconnection of the plug connections.

The plugs and sockets can be coded for non-interchangeability and specific applications.

None of the components has screws. The available connection methods include crimping or cage-type spring-tension terminals.
