COMET INDUSTRIAL PLUGS & SOCKETS :

Comet brand industrial plugs & sockets combine simplicity, convenience & reliability through their unique design which makes use of the concept of spring-loaded butt-type contacts, instead of the conventional concept of Pin-and-sleeve type. They are available in several contact combinations both for power as well as control circuits and have advantages like positive, bayonet-type fitting between plugs & sockets shrouding of live parts from accidental human touch reliable earthing through butt-type sliver tipped contact, suitability for out door application and for use under conditions of high vibrations. Plugs & sockets up to 5 pins for power circuit and rated for 30A at 500 volts and those meant for use on control circuits up to 12 Pins, have ratings of 12A at 500 volts.

THEY PROVIDE THE FOLLOWING ADVANTAGES :
* Pre-determined optimum contact pressure for high conductivity.
* Low contact-resistance-low temperature rise.
* Infinite plug interchangeability with consistent contact pressure no difference in contact-   
   pressure with new or old plugs.
* Non deteriorating contact carrying surface.
* Self aligning self wiping contacts and wipe align when the plug has been fully inserted.
* Reliability of silver contacts unaffected in high temperature conditions.

Conventional sliding pin-and-sleeve contacts require pin-and-sleeve contacts pressures to be at right angles to the force necessary to insert and remove the plug and these pressures often make it difficult to insert and remove the plug. However, comet plugs & sockets have butt-type contacts where the contact pressure is Parallel to the forces required to insert and remove the plug as contact force is directly opposite to that required to insert the plug, the contact pressure springs assist the removal of plug from the socket.

* INTERCHANGEABILITY OF INTERIORS : The interiors of plugs & sockets are inter changeable and are retained by circlips. The easy interchangeability enables many different arrangements to be made up from a minimum stock of components.
* EARTHING : The earth control is always in the central position thus eliminating the possibility of inadvertently connecting a live contact to earth it is also impossible to lodge or wedge bare conductors in the socket to obtain a supply.
* SOCKET COVER : The socket is fitted with a strong spring closed gasketted cover making the unit suitable for out door use.
* SELF LOCKING DESIGN : The plug cannot be pulled out of the socket, by its cable or fallout due to positive bayonet type fitting.
