In-House Quality Control
We don't guess; we test. Every SFE industrial plug and socket is rigorously engineered and validated in our own laboratory to guarantee absolute IEC 60309 compliance.
Temperature Rise Test
Monitors heat generation under continuous full load to guarantee the temperature stays well below the IEC 50K safety limit. Zero risk of melting.
850°C Glow-Wire Testing
Ensures our PA66 plastic carriers are strictly self-extinguishing (0s ignition) and fully fire-proof under extreme electrical short-circuit faults.
Hi-Pot / Dielectric Test
Verifies extreme insulation strength. We apply high voltage surges to ensure zero dielectric breakdown, preventing electric shock hazards in harsh environments.
IP44/IP67 Waterproof Test
Simulates extreme weather conditions, from heavy splashing to high-pressure water jets, ensuring absolute waterproof integrity for outdoor applications.
Pendulum Impact Test
Applies concentrated kinetic strikes to the housing surface to verify extreme mechanical impact resistance, critical for heavy industry and mining operations.
Extreme Weather Simulation
From -30°C freezing cold to +80°C scorching heat. We cycle our products through extreme temperature chambers to guarantee reliable performance globally.
