Zhejiang Hongxiang EMC Shielded Cable Glands: Core Summary

Electromagnetic Compatibility (EMC) is critical for stable operation of equipment in industrial automation, new energy, and rail transit. With industrial intelligence advancement, sensors and controllers require enhanced resistance to electromagnetic interference (EMI/RFI). Backed by nearly 20 years of experience and ISO9001/IATF16949 certifications, Zhejiang Hongxiang independently developed EMC shielded cable glands. These glands feature optimized shielding and protection, effectively suppressing EMI and blocking pollutants. They have been applied in core equipment of Yutong Bus, ABB, Philips, and major projects like the "Liaoning" aircraft carrier, with proven performance in harsh conditions.

I. Product Positioning and Core Design

Tailored for high-EMI industrial scenarios, Hongxiang EMC cable glands integrate electromagnetic shielding, environmental protection, and strain relief. Compliant with EN50262 and UL 514B standards, they adopt optimized conductive shielding and high-performance seals, achieving reliable cable shield fixation and bidirectional EMI control. Integrating waterproof, dustproof, corrosion-resistant, and vibration-resistant functions, they fit harsh environments without additional accessories, simplifying installation and maintenance.

II. Material Composition and Key Performance

Core structural components (gland body, nuts) are made of nickel-plated high-purity brass, ensuring excellent conductivity, mechanical strength, and corrosion resistance. Shielding components include tin-plated phosphor bronze shrapnel and grounding rings for reliable signal conduction; high-end models add conductive elastomer seals. Standard seals use NBR, with EPDM, silicone rubber, or CR customizable for special conditions. Auxiliary parts (gaskets, clamping claws) ensure sealing continuity and cable protection.

Key performance: Shielding effectiveness 60dB@1GHz-10GHz, grounding resistance ≤5mΩ; IP68 protection (1m water immersion for 30 minutes); operating temperature -40℃~+100℃ (short-term 120℃, customized high-temperature version up to 200℃); tensile strength ≥1500N, vibration resistance compliant with IEC 60068-2-6; 96-hour salt spray resistance; flame retardancy UL94 V-2 (V-0 customizable). Certified by CE, RoHS, REACH, UL, etc., with ATEX explosion-proof options available.

III. Specification System and Dimensional Parameters

Compatible with metric, PG, G/BSP, and NPT thread standards, directly matching equipment openings without adapters. Core thread specifications: Metric (M6×1.0~M63×1.5), PG (PG7~PG48), G/BSP (G1/8"~G1-1/2"), NPT (NPT1/8"~NPT1-1/4").

Core model parameters for quick selection:

Customization services (special diameters, non-standard threads, explosion-proof, etc.) are available. Standard configuration includes nickel-plated brass body, seals, shielding components, etc.; bend-resistant tails and anti-pull-off structures are optional.

IV. Scope of Application and Usage Boundaries

Applicable to fixation, sealing, shielding, and strain relief of round non-armored/light armored shielded cables (control, signal, instrument, communication, low-voltage power cables), compatible with PVC, rubber, PU, PE sheaths. Not applicable to unshielded cables, high-voltage armored heavy cables, and ultra-high-voltage explosion-proof special cables.

Widely used in industrial automation, new energy (EV three-electric systems, inverters), rail transit, power distribution, communication/security, petrochemical (explosion-proof models), and general machinery. Suitable for indoor/outdoor environments, resisting humidity, salt spray, vibration, and high EMI. Prohibited in strong corrosive, uncertified explosive, and ultra-high-temperature (over 200℃) scenarios.

V. Selection and Installation Specifications

Selection principles: Match cable outer diameter (prioritize middle range), confirm shield component compatibility, select appropriate shielding effectiveness (≥60dB for high-sensitivity scenarios). Use matching threads to avoid adapters. Choose seals based on conditions (NBR/EPDM for outdoor, silicone for extreme temperatures).

Installation notes: Strip 5-8mm of cable sheath to expose shield, ensure tight contact with shrapnel/grounding ring; tighten nuts evenly without overforce; check sealing and shielding continuity after installation. Separate power and signal cables during wiring; use bend-resistant tails for outdoor/vibration scenarios.

VI. Core Advantages and Value Embodiment

Core advantages: Efficient EMI shielding, integrated IP68 protection, full-scenario adaptation (multiple threads/customization), and reliable quality (certified, verified by renowned customers). It improves equipment stability, reduces maintenance costs, and supports industrial intelligence upgrading.
