Performance Advantages
✓ Superior Environmental Sealing – Integral grommet or individual wire seal designs ensure IP67/IP68/IP6K9K protection against dust, water, and high-pressure washdown
✓ Exceptional Vibration Resistance – Certified to SAE J2030-201506; withstands 20G vibration at 10-2000 Hz across three axes with no electrical discontinuity >1μsec
✓ Positive Locking Mechanism – Lever-driven coupling with CPA (Connector Position Assurance) provides tactile and audible feedback for secure mating confirmation
✓ Mixed Signal & Power Capability – Single housing accommodates both signal contacts (up to 13A) and power contacts (up to 30A), reducing connector count and installation complexity
✓ Harsh Environment Durability – Resistant to thermal shock (-55°C to +125°C), physical shock (50G peak), salt spray (96 hours), and extreme humidity
