| Cable Diameter Range | 5–9mm / 9–12mm Dual-range flexibility | Fixed sizes only |
| Voltage/Current | 24A / 450V | 16A / 250V |
| Certifications | CE, RoHS, TUV, SAA | Basic safety compliance |
CE Certified RoHS Compliant TUV Approved SAA Certified
Solar/Wind Power: Resists salt corrosion and UV degradation in coastal installations.
Solar Water Heaters: Maintains integrity in high-heat, high-humidity environments.
LED Public Lighting: Protects circuits in streetlights, tunnel lights, and billboards.
Mining & Marine: Survives submersion, vibrations, and chemical exposure.
Smart Agriculture: Prevents moisture ingress in outdoor irrigation control systems.
Water Treatment Plants: Withstands constant humidity and chemical exposure in pump stations and filtration systems [9](@ref).
Amusement Rides: Ensures electrical safety in high-vibration, weather-exposed attractions [6](@ref).
Industrial Vehicles: Provides reliable connections for charging ports and power systems in harsh operating environments [10](@ref).
Acid/alkali resistance, impact-proof, and non-degrading in temperatures from -40°C to 120°C. IP68 protection prevents dust and water ingress even under 1 meter of water for 30 minutes [11](@ref).
Transparent shell enables visual fault inspection without disassembly. Dual-range cable glands (5–9mm and 9–12mm) accommodate different wiring needs without additional adapters.
PC+PA66 composite provides 3× longer service life than standard nylon connectors in chemical exposure tests. UV-resistant formulation prevents degradation in direct sunlight applications [7](@ref).
Apply silicone gel to threaded ports before tightening glands
Torque connectors to 0.8–1.2 N·m to prevent overtightening cracks
Use cable glands compatible with jacket material to prevent slippage
"Use ferrules on stranded wires to avoid shredding under PA66 clamps"
Mixing metallic/non-metallic glands (causes galvanic corrosion)
Exceeding 24A load with ambient temperatures >60°C
Using in hazardous areas without proper explosion-proof certification [8](@ref)
Replacing bulky metal enclosures, the GM series cuts installation time by 40% and maintenance costs by 60% for LED tunnel projects in Zhejiang's high-humidity regions. Its PA66 connectors outperform nylon rivals in lifespan tests by 3×.
