The Metal Shielded Cable Gland is a professional-grade solution designed to provide electromagnetic compatibility (EMC) and ensure optimal cable shielding continuity. Built from nickel-plated brass or stainless steel, it delivers outstanding electrical conductivity, mechanical protection, and corrosion resistance, even in demanding industrial environments.
Equipped with an integrated 360° grounding structure, the gland securely clamps the cable’s braided shield, creating a continuous conductive path that eliminates electromagnetic interference (EMI) and radio frequency interference (RFI). This ensures stable signal transmission and enhanced system reliability.
With IP68-rated sealing performance, the gland prevents ingress of water, oil, or dust, providing both mechanical and environmental protection. Its robust design also offers excellent strain relief and resistance to vibration, ensuring long service life.
Ideal for automation systems, communication devices, power converters, and data transmission equipment, the Metal Shielded Cable Gland helps maintain signal integrity in high-frequency and high-noise environments.
Available in PG, NPT, and Metric thread types, and compliant with CE, UL, and ROHS standards, this gland is the professional choice for secure, shielded, and interference-free cable connections in modern industrial systems.
The EMC cable gland means the cable gland with Electromagnetic Compatibility, it has the ability of a device or system to operate in its electromagnetic environment without causing unacceptable electromagnetic interference to any device in its environment.
EMC cable glands contact the cable shield, compress the cable seals and provide electromagnetic(EMC) protect the throughout cables and the equipment at the joint point.
EMC cable gland normally made by the materials in stainless steel or brass, it provides ideal strain relief function, easy for installation and long and short entry available for customization. The thread type could be PG type, metric type and NPT type as customers need, all types of cables are in the clamping range of our cable glands.
The EMC cable gland has been specially designed to use cable gland as an end body. When the isolation cable enters the EMC cable gland, the metal contact piece attached to the cable gland can be used to make contact with the metal isolation woven mesh inside the cable. In turn, the electromagnetic waves of the interference are guided to the ground line, so that the electromagnetic interference source can be evacuated. This cable gland can be fully applied to all outgoing areas where anti-magnetic waves are required.
