Modern technologies are constantly becoming more demanding and complex. This increases the vulnerability of electronic components to electromagnetic disturbances. To protect against such interactions, we offer two different approaches for EMC cable glands. Our EMC cable glands are equipped either with an earthing cone or a contact spring insert. Both versions ensure an effective 360° shielding concept as well as permanent sealing performance with IP68 / IP69 protection.
New in our range is our EMC locknut: The MagikNUT®. This is a polyamide locknut with an integrated stainless steel clip for EMC shield contact. Find out more about our MagikNUT®.
EMC (Electromagnetic Compatibility) refers to the ability of electronic devices to operate in an electromagnetic environment without interfering with other devices or being affected by them. Electromagnetic compatibility is essential to ensure the smooth functioning of electrical equipment.
WISKA EMC cable glands are characterised by their immunity to electromagnetic interference (resistance to external disturbances). They are often used in sensitive areas such as medical technology, industry and mechanical engineering, the automotive sector, marine applications, and telecommunications. WISKA offers a broad range of shielded cable glands with EMC according to DIN standards with high interference resistance.
In the production of WISKA EMC cable entry, either an earthing cone or a contact spring insert is used. The advantage of these EMC gland designs is an effective 360° shielding concept combined with permanent sealing performance of IP68 / IP69. They ensure reliable dissipation of interference currents and significantly contribute to compliance with electromagnetic compatibility in sensitive applications.
Thanks to their robust design and high-quality materials, WISKA cable glands with EMC standard are suitable for use in demanding industries. They offer the required mechanical strength and long-term operational reliability.
The EMC Directive 2014/30/EU regulates in Europe how resistant electrical equipment must be to electromagnetic interference (immunity). It also defines how much electromagnetic emissions devices are allowed to produce. EMC testing therefore generally applies to all electrical devices and systems that may be affected by such electromagnetic disturbances.
Devices covered by the EMC Directive include, for example, industrial installations, control cabinet components, household appliances, and IT and communication equipment. Special regulations and standards apply, among others, to radio modules or systems as well as medical devices.
EMC testing is necessary to ensure that electronic devices and their components have sufficient immunity to interference. The key requirement is that they function reliably in an electromagnetic environment. EMC testing evaluates the resistance of an electrical or electronic device to electromagnetic influences.
The development of EMC procedures, guidelines and updates plays a crucial role in the safety and reliability of electronic devices across various application areas. EMC testing is based on the EMC Directive 2014/30/EU as well as standards such as DIN EN 61000. WISKA complies with these standards, and regular verification of EMC conformity ensures smooth and long-term operation of the equipment.
The basis for EMC certification is either laboratory EMC testing or a technical assessment of the product. During immunity testing, the device is deliberately exposed to various interference factors. These include electrostatic discharges, surges, or high-frequency electromagnetic fields.
The device is tested in a standardised setup that closely simulates real operating conditions, including typical wiring and operating states. This ensures that the device operates reliably and in compliance with standards even under real-world interference conditions.
The most important aspect of EMC testing is whether the device or system continues to function properly or whether malfunctions or failures occur. The evaluation is carried out in accordance with DIN EN 61000.
In addition to immunity testing, emissions are also usually measured to ensure that the device itself does not generate unacceptable electromagnetic interference.
