The 4th generation of Control 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 750V.
Pin and socket inserts are numbered front and back to assist wiring and avoid termination errors. Crimp and solder inserts available.
Eases accessibility for termination as tube fitted after termination complete, along with allowing easy installation into the required keyed position (See 4)
Optional locking pin provides the facility for mated connectors to be permanently locked, via the use of a padlock, ensuring they cannot be separated under load. (Padlock not supplied)
The unique visual 5 position insert keying system (3 on Ex16) along with the integral machined keyways prevent contact damage and ensures safe use by eliminating the possibility of misconnection of adjacent circuits.
Allows the connector to be installed onto a pre-assembled cable gland. Connector is rear loading and includes locking engaging nut.
Unique ACME thread offers a smooth and quick fully mating action.
Provides direct inspection of the flameproof seal and offers users the peace of mind that the connector is safe for installation.
Connector plugs and receptacles come complete with anti-rotation ring, which when fitted between the connector and gland, helps to eliminate the possibility of the gland loosening, locking this in position.
The flameproof cap must be fitted to the connector before the power is restored to the disconnected circuit. The receptacle cap and plug cap are available in acetal and provide an IP rating of IP66/67. They may only be used when the socket or plug is not re-energised following disconnection. For connector plugs and connector receptacles cable glands are required to terminate incoming cables. Hawke recommend the ICG 653/UNIV cable gland is used.

Hawke Control connectors have a maximum working voltage of 750V DC (750V AC) as standard.
3rd & 4th generation Control connectors can be connected together within certification.
Other voltages available on special request.
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 below for the maximum allowable dissipated wattage per connector size).
|Connector Size||Upper Ambient
Temperature of +40°C
Temperature of +50°C
Temperature of +60°C
|Temperature Class||Temperature Class||Temperature Class|
|Maximum allowable dissipated wattage|
|Other ambient temperature options can be extrapolated from
table 1 above, or contact Hawke International for more information.
|Contact Size||Combined Cable And Contact Resistance (Ohms)||Contact
W = Dissipated wattage factor of the connector
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 above).
R = The combined cable and contact resistance (see table 2 above).
Values pertinent to these definitions must then be input into the relevant fields below to calculate the dissipated wattage (W) of your chosen arrangement:
(Note: The results must be lower than the maximum figure shown in table 1 above, for the appropriate temperature class and ambient temperature).
e.g. T6 40°C ambient application with 9 x 1.5mm² conductors running at 7 amps.
N = 9 contacts
I = 7 amps
R = 0.0166 Ω (1.5mm² soldered combined cable and contact resistance)
Therefore W = 9 x 49 x 0.0166 = 7.32 watts.
Therefore an Ex25 Connector should be specified for this application as the shell size can accommodate the required 9 x 1.5mm² pin / socket inserts (see insert selection table) and the resultant dissipated wattage (7.32 watts) is below the maximum permitted 8 watts (see table 1 above).
This equation can also be transposed to facilitate the calculation of the maximum number of conductors permitted in your selected connector (calculator 2 below ) and the maximum allowable current within the upper ambient temperature of your location (calculator 3 below).
Note: Unless otherwise requested, connectors will be marked as T5 with an upper ambient temperature of +40°C.
Hawke International does not recommend the use of their ControlEx Connectors in applications where rigid PVC/SWA/PVC power cabling (typically to BS 6346 standards or equivalnts) is used in portable/semi-portable applications.
