Product Details
| Product Features | Engineering Advantages | Customer Benefits |
| Extreme Temp Rating (170°C) | Utilizes advanced Nylon 6/6 materials designed to survive thermal stress that melts standard connectors. | Engine Bay Reliability: Perfect for placement near turbochargers or exhaust sensors, ensuring no melting or signal loss under the most intense heat conditions. |
| Clean Body MCON 1.2 Design | Optimized for the MCON 1.2mm terminal system with integrated primary and secondary locking (TPA). | Fail-Safe Performance: Guarantees terminals are locked securely, preventing terminal push-out during high-vibration off-road or heavy-duty trucking operations. |
| 48V Multi-Voltage Capability | Designed to handle the insulation requirements of modern 48V mild-hybrid and EV electrical architectures. | Future-Proof Design: One connector solution that works across 12V, 24V, and 48V systems, reducing inventory complexity for diverse vehicle fleets. |
| IP67 Rated Sealing Interface | Engineered with high-quality internal seals that prevent the ingress of water, oil, and road salt. | Zero Corrosion Maintenance: Protects sensitive power and signal circuits from environmental damage, significantly lowering the total cost of ownership. |
