EMC Metric Long Thread Metal Cable Glands
EMC Metric Long Thread Metal Cable Glands are designed for cable entry, mechanical retention, and electromagnetic compatibility in electrical enclosures and industrial equipment. Featuring a metric threaded mounting section with an extended thread length, these glands support installation in compatible panels and enclosure walls where additional thread engagement is required. The metal body and EMC contact components help establish electrical contact with cable shielding, supporting shield continuity when correctly installed. Available in different metric thread sizes and cable diameter ranges, they are suitable for control cabinets, automation systems, communication equipment, and industrial electrical installations.
Hangzhou Gordon Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of emc metric long thread metal cable glands in China, also supports custom service. Please feel free to wholesale advanced emc metric long thread metal cable glands made in China here from our factory.
EMC Shielding & Electromagnetic Compatibility
EMC Metric Long Thread Metal Cable Glands are designed for use with compatible shielded cables to help reduce low-frequency electromagnetic interference in electrical equipment. The gland's shielding contact structure supports electrical continuity between the cable shield and the metal enclosure when correctly installed. Effective EMC performance depends on proper shield contact, installation, and the overall system grounding design.
- Shielded Cable Compatibility: Designed for applications using compatible shielded cables.
- EMC Contact Design: Helps establish an electrical connection between the cable shield and the enclosure.
- Interference Reduction: Supports electromagnetic compatibility in low-voltage electrical and control systems.
Material Construction & Chemical Resistance
The gland uses nickel-plated brass for parts A, C, D1, and F, UL-approved PA66 for part E, and EPDM rubber for parts B and D, according to the supplied component specifications. This material combination provides a metal mounting structure, polymer clamping components, and elastomeric sealing elements for industrial cable entry applications.
- Nickel-Plated Brass Components: Provide mechanical strength and a protective plated surface.
- UL-Approved PA66 Component: Offers a lightweight, electrically insulating polymer structure.
- EPDM Sealing Components: Support sealing performance under the specified operating conditions.
- Resistance to Common Media: Designed to resist salt water, weak acids, alcohol, oil, grease, and common solvents; confirm compatibility with the specific chemical, concentration, temperature, and exposure duration.
Protection Rating & Operating Temperature
Designed for demanding electrical installations, the cable gland has a specified protection rating of IP68 at 10 bar and an operating temperature range of -40°C to +100°C.
- IP68 Protection: Helps protect the enclosure entry against dust and water ingress when correctly installed under the applicable test conditions.
- Operating Temperature: Suitable for the specified range of -40°C to +100°C.
- Secure Cable Entry: The clamping and sealing components work together to support cable retention and environmental protection.
- Installation Requirements: Actual protection depends on cable diameter, enclosure mounting, assembly, and the specified test conditions.
FAQ
Can an EMC cable gland be used with an unshielded cable?
An EMC cable gland can sometimes provide mechanical cable entry for an unshielded cable, but its electromagnetic shielding function requires a compatible shielded cable and suitable shield contact. Choose the gland according to the electrical and mechanical requirements of the application.
Can the gland be installed on a painted or powder-coated enclosure?
It may be necessary to provide a suitable conductive contact area between the gland and the enclosure. Paint or powder coating can electrically isolate the metal surfaces, so follow the equipment design requirements for achieving reliable bonding.
Does using an EMC cable gland eliminate all electromagnetic interference?
No. The gland is one component of an overall EMC design. Cable shielding, grounding and bonding, cable routing, connector interfaces, and equipment layout all influence the final result.
Can the cable gland be removed and installed again during equipment maintenance?
The supplied design indicates that the sealing nut can be reopened. Before reinstallation, inspect the threads, clamping claws, and sealing components for wear or damage, and follow the manufacturer's instructions to ensure the assembly remains suitable for service.
