Four Core Subsystem Architectures

Application-specific interconnect stacks validated for the thermal, vibration and ingress demands of each vehicle platform domain.

01

Commercial Vehicles & Heavy-Duty Off-Highway

Sealed, vibration-hardened interconnect systems engineered for heavy-duty duty cycles — mud, slurry, oil contamination and continuous mechanical shock on trucks, construction and agricultural equipment.

Vibration standard: rated to SAE J2030 (20G) random vibration profiles with IP68 sealing and mechanical secondary lock — connector retention validated for continuous off-road shock loading.
02

Electric Vehicles (EV) & Battery Management Systems

High-current, high-isolation interconnect architectures for EV three-electric systems and BMS, engineered for 1500V-class platforms and ultra-low-resistance power paths.

Electrical performance: 1500V AC dielectric withstand voltage and <2.5 mΩ ultra-low contact resistance for high-current, high-isolation EV power and BMS circuits.
03

Automotive Lighting, ADAS Radar & Engine Sensors

Compact, reliably sealed interfaces for lighting modules, millimeter-wave radar units and engine sensor networks — where space is tight and ingress protection is non-negotiable.

Sealing & mating: IP67 silicone single-wire seal (SWS) system with tactile quick-latch feedback for reliable one-hand mating in restricted installation spaces.
04

Body Electronics, Cockpit & Power Distribution

Overcurrent protection and modular power distribution components for body electronics, cockpit modules and in-vehicle accessory circuits.

Material & reliability: flame-retardant PA66-GF30 housing rated UL94 V-0, with vibration-resistant contact retention for in-cabin and under-hood power distribution.
