In industry and construction sector plug connectors are usedwidely. The operational requirements for which have increased. These connectors should have higher reliability and safety than conventional plugs and sockets. In general industrial plug in connectors necessarily meet the following criteria, exclude the possibility of accidental shutdown which can lead to an accident, they are protected from dust, moisture, and corrosive media, special connectors are suitable for explosive and fire hazardous conditions, special connectors for operation in high humidity conditions, the connectors differ in different nominal voltages, currents and the number of phases.Some industrial connectors can be used in everyday life for example for connecting diesel generators.
How to choose the capabilities?
There are many outlets and plugs differing in size, number of pins which is related to the current as well as the number of phases supplied. Connections have a minimum degree of protection of the shell IP44that allows them to be used in the open air. Along with the ability to transmit large currents industrial connectors prevent the possibility of accidentally connecting household appliances to sockets that are not intended for them, the shape of the plug simply will not work. For the manufacturing precision feedthrough products such as these, the options are open now.
Both plugs and sockets are color coded to indicate the range of voltages and frequencies used in a particular network. For example, the yellow color indicates a range from 100 to 130 volts at a frequency of 50 to 60 Hz. The blue color indicates a range from 200 to 250 volts at a frequency of 50 to 60 Hz. Red means a range from 400 to 480 volts at a frequency of 50 to 60 Hz. The color code refers to the highest voltage value between phases. Most often the blue connectors serve as weatherproof external sockets for connecting external devices. Yellow is for a transformer supply voltage of 110 volts use in construction sites to protect workers from electric shock, using electric tools on the construction site in the open air.Typically, large 32 amp blue connectors provide power to the structure such as a hovel and mobile trailers feed small 16 ampere blue sockets.
Conclusion: Power Connectors
Connectors are available in several versions designed so that a plug of one particular type can be connected only to a specific type of socket. The diameter of the annular body is different for currents of 16, 32, 63 and 125 amperes. The combinations of frequency and voltage differ in the location of the ground, allocated by the key groove.The first pin can be located in one of the 12 positions located under 30 degree on the circle on which the pins are mounted. The position is determined by the socket. The first pin has a larger diameter than all the others.
