Electromagnetic Compatible (EMC) Plugs & Sockets

Electromagnetic Compatibility (EMC) is the ability of a product to operate satisfactorily in its electromagnetic environment without introducing electromagnetic interference itself. But what does this mean concretely for the industrial sector?

The Electromagnetic Compatibility Directive (EMCD) ensures that electrical and electronic equipment does not generate, or is not affected by, electromagnetic disturbance

The MARECHAL solutions are made up of a DECONTACTOR™ EMC industrial plug and socket outlets range, specifically designed up to 400 A and 1000 V. They help to avoid accidental shutdowns due to electromagnetic interference.

➡️ Thorne & Derrick have been appointed as official distributors and stockists of Marechal plugs and sockets in the UK, as of the 1st March 2023. Our demonstrated knowledge and expertise in the industry enables us to deliver the complete Marechal product offering in both Industrial and Hazardous Areas.

Where do these interference come from?

Disruptions can have many causes:

Natural factors, such as lightning
Devices designed to transmit/receive waves, such as mobile phones, radars, radio, television, etc
Devices that generate emissions, such as engines, digital circuits, etc

CONSEQUENCES OF ELECTRO-MAGNETIC WAVES

Electromagnetic waves can disturb a signal, causing the electrical installation, a robot or machine to malfunction or transmit an incomplete or erroneous message (data, ignition order, etc.) or even completely block an industrial manufacturing process.

As a result, these disruptions can impact the proper functioning and productivity of a plant as well as the safety of the site.

The best way to protect yourself from electromagnetic pollution is by ensuring the continuity of the shielded cable and thus the non-disruption of signals, using EMC products.

FIGHT ELECTROMAGNETIC INTERFERENCE WITH MARECHAL® SOLUTIONS:

Complete EMC Protection & Automatic IP55

Boxes and installation accessories in metal
All the mounting surfaces ensure optimal electrical conductivity
Special seals in metallic material in order to ensure an IP55 protection (waterproofness) as well as optimal EMC performances. The IP protection degree is obtained automatically when connecting the plug or shutting the lid. No other operation is necessary
On request, the plugs and socket outlets can be supplied with armoured cable glands

Power & Control

The DECONTACTOR™ EMC auxiliary contacts allow the process control such as connection control, motor thermal control, programmable logic controller (PLC), signal transmission, etc.
The EMC option allows a reduction in the power (in dB) of their inherent emission of electromagnetic waves. The electromagnetic compatibility (EMC) trials are carried out on all products according to the IEC 62153-4-5 : 2016 norm. In a frequency range between 30 MHz and 1000 MHz, the EMC option offers a reduction between 30 dB and 70 dB of electromagnetic emissions.

OPTIMAL TRANSMISSION OF POWER

The socket-outlets resist to corrosion and chemical agents. The silver-nickel butt contact tips with springs ensure a permanent contact pressure and an optimal conductivity even after years of intensive use. The specifically designed cable terminals provide our socket-outlets with optimal resistance to vibrations (especially preventing cable loosening) and temperature variations as well as outstanding cable anchoring.

RED All the external surfaces of the devices are not treated so as to ensure optimal electrical conductivity.

ORANGE The conductive sealings are made of either metallic fibers, Monel wires silicone or graphite-loaded wires silicone, ensuring excellent EMC performances.

MARECHAL has developed a simple and reliable solution with outstanding performances in electromagnetic environments. This solution is available for MARECHAL® industrial or hazardous area device ranges, for high currents up to 1 250 A or for signal and control up to 37 contacts. This solution is particularly adapted to electromagnetic environments involving variable frequency drives for electric motors.
