1. Product Overview
The MAIYUXIN NACS AC Charging Inlet is engineered for North American electric vehicles and charging equipment manufacturers. As the industry transitions to the SAE J3400 standard, this inlet provides the essential AC charging interface for Level 1 and Level 2 applications. Unlike legacy connectors, the NACS design uses a streamlined, single-plug architecture, eliminating redundant pins and simplifying the user experience.

3. Key Features & Industrial Benefits
-
Precision Contact Engineering: Featuring silver-plated copper alloy terminals, this inlet minimizes contact resistance, ensuring that even during high-current 80A sessions, heat dissipation remains highly efficient.
-
Advanced Thermal Monitoring: Every NACS AC inlet is equipped with dual temperature sensors on the primary power terminals. This allows the vehicle’s onboard charger to monitor real-time thermal data and prevent overheating during long-duration charging.
-
PLC Communication Compatible: The Control Pilot (CP) and Proximity Pilot (PP) pins are designed to support both analog pulse-width modulation (PWM) and digital Power Line Communication (PLC), as required by ISO 15118 standards.
-
Rugged Construction: Built to withstand North American climates, the inlet is salt-mist tested and UV-resistant, ensuring the exterior housing remains crack-free for the life of the vehicle.
-
Compact Integration: Its lightweight, modular design is perfect for EV conversions and new vehicle platforms where interior space behind the charge port flap is limited.
