Product Core Functions
Advanced engineering solutions that deliver measurable reliability advantages and reduce total cost of ownership for your customers.
Design
Platform-Based Design
The products are designed using platform approaches featuring a gear transmission system with high reliability. By leveraging shared platform architecture, product competitiveness is improved through lower investment and reduced cost -- enabling faster deployment across a wider range of vehicle applications.
Angle Sensor
Non-Contact Angle Sensor
The unit design of the high-reliability non-contact angle sensor delivers significant advantages in durability, signal integrity, and electromagnetic compatibility for demanding automotive environments.
PCB-Free Structure
Eliminates the PCB board entirely, delivering excellent weather resistance and extending operational lifespan in harsh environments.
Single-Chip + Integrated EMC
Single-chip packaging with an integrated EMC (Electro Magnetic Compatibility) anti-noise loop delivers superior anti-electromagnetic interference performance.
Mechanical
Structure
High-Reliability Mechanical Structure Design
The product's mechanically robust structural design incorporates needle roller bearings at both ends, which reduces frictional resistance during shaft rotation. This design effectively prevents throttle body jamming even under severe carbon deposition conditions -- significantly lowering after-sales costs and enhancing product competitiveness.
