3 Ex Connector Benefits IMPLE TO UE - QUICK TO TERMINATE Temporary but safe disconnection of power is critical in many industries. To meet this requirement Hawke International has introduced a new series of EExd Connectors that are approved, easy to use and exceptionally robust. They permit the safe and rapid service, repair and replacement of key plant, 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 Zone 1 and Zone 2 explosive environments commonly found in oil and gas exploration, production and process plants. However, their features also offer benefits in Zone 21 and Zone 22 explosive dust environments, or in harsh and hostile non-explosive applications. In compliance with the 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, along with the acclaimed Acme mating thread; enabling quick connection whilst preventing thread binding or galling. Ex Connector Benefits Additional Benefits Include:- Faster Assembly An internal sleeve provides an extended installation keyway which assists connector assembly by making pin/socket insertion easier and quicker. This feature also helps to prevent insert misalignment and potential contact damage. Impossible to Cross-mate The unique visual 5 position keying system (3 on Ex16) prevents contact damage and ensures safe use by eliminating the possibility of misconnection of adjacent circuits. Fully Inspectable Flameproof Barrier The revolutionary removable compound chamber technology first seen on our compound cable glands is now incorporated into our Bulkhead Connector. This allows direct access for visual inspection of the flameproof barrier seal and offers users the peace of mind that the connector is safe for installation into Flameproof and Increased afety equipment. High Reliability Contacts Each Pin and ocket is fitted with Multilam Band Technology to ensure reliable low resistance connection on each coupling. Quick and Easy Fieldwiring The Pin AND ocket Inserts are numbered front and back to assist wiring and avoid potential termination errors. 2 International

7 Ex Connector Wattage Calculation To select the shell size of the connector, it is essential that you calculate the dissipated wattage of the arrangement. This ensures that the arrangement does not exceed the maximum permitted temperature classification with regard to the upper ambient temperature for the area of installation. (please refer to table 1 for the maximum allowable dissipated wattage per connector size). Connector ize Ex 16 Ex 25 Ex 32 Ex 40 Ex 50 Ex 63 W = Dissipated wattage factor of the connector TABLE 1 TABLE 2 Upper Ambient Temperature of +40 C Upper Ambient Temperature of +50 C Temperature Class Temperature Class T6 T5 T6 T5 5W 7W 4W 6W 8W 10.5W 12W 13W 11W 14.5W 17W 20W 6W 8W 9W 10W Upper Ambient Temperature of +65 C Temperature Class T6 T5 2W 4W 17W 29W 13W 24W 6.5W 13W Maximum allowable dissipated wattage Dissipated Wattage Calculation Equation Definitions 10W 12W 14W 17W 3W 4W 4W 5W 6W 8W 9W 10W Contact ize 1.5mm² 2.5mm² 6mm² 10mm² 16mm² 25mm² mm² Contact Resistance (Ohms) Ω Ω 0.00 Ω Ω Ω Ω Ω Contact Current Rating 10amps 17amps 30amps 78amps 78amps 125amps 125amps Other ambient temperature options can be extrapolated from table 1 above, or contact Hawke International for more information. Ex Connector Wattage Calculation N = The number of conductors to be terminated/number of contacts required. (Note: A contact comprises of a pin and socket). I = The current requirement per contact. (Note: This must be equal to or less than the maximum current rating of the contact, as shown in table 2). R = The contact resistance (see table 2). Values pertinent to these definitions must then be input into the following equation to calculate the dissipated wattage (W) of your chosen arrangement: W = N x I² x R (Note: The results must be lower than the maximum figure shown in table 1 for the appropriate temperature class and ambient temperature). e.g. T6 40 C ambient application with 4 x 1.5mm² conductors, running at 9 amps. N = 4 contacts I = 9 amps R = Ω (1.5mm² contact resistance) Therefore W = 4 x 81 x = 2.37 watts. Therefore an Ex25 Connector should be specified for this application as the shell size can accommodate the required 4 x 1.5mm² pin/socket inserts (see page 3 - Insert election Table) and the resultant dissipated wattage (2.37 watts) is below the maximum permitted 8 watts (see table 1). This equation can also be transposed to facilitate the calculation of the maximum number of conductors permitted in your selected connector 1 and the maximum allowable current within the upper ambient temperature of your location 2 1 N = W R x I² 2 I = W N x R (Note: The result of equation 2 must not exceed the maximum current rating of the contacts (see table 2). Note: Unless otherwise requested, connectors will be marked as T5 with an upper ambient temperature of +40 C. 6 International
