Ex Connectors Selection Overview
Our connectors are ideal for use in gas hazardous areas commonly found in Oil and Gas exploration, production and process plants. Their features, however, also offer numerous benefits in explosive dust environments as well as harsh and hostile non-explosive applications where temporary but safe disconnection of power is critical.
Our Ex range of Connectors permit the safe and rapid service, repair and replacement of key plant, provide quick connection to temporary equipment and greatly reduce hook-up time in capital-intensive processes.
The Ex range of Connectors cover three main application areas: instrumentation, control and power. For a guide as to which Ex Connector may be best suited to an individual application the table below outlines the main variables.

InstrumEx
This revolutionary design allows the live mate and de-mating of signal and low power in hazardous areas safely and quickly. The InstrumEx connector is available with two insert options: the 4-way option will accept cores ranging between 0.5mm² and 2.5mm² and can operate up to a maximum current of 10A (AC1) at 250V AC & 2.5A (DC1) 60V DC. The 8-way option, designed predominantly for Ethernet applications, will accept cores ranging between 0.14mm² and 0.37mm² and can carry 1A (AC1) at 60V AC & 0.5A (DC1)60V DC. InstrumEx connectors include an integral Hawke cable gland for easy termination of both armoured and un-armoured cables.
ControlEx
The 3rd generation of ControlEx connectors include many features and refinements as a result of consumer feedback, which makes them particularly suitable for control and low/medium power applications. The robust stainless steel body can hold up to 60 contacts and will accept conductor sizes ranging between 0.5mm² and 35mm², operating up to 125A and 660V.

PowerEx
The PowerEx range of connectors have been designed specifically for the extremely demanding requirements of higher power applications. Inserts are available with 1 to 4 contacts with a conductor acceptance range of between 50mm² and 630mm² operating up to 780A and 750V as standard. Other voltages available on special request.
