Intelligent Contactor

The intelligent contactor developed by Vicvac Electronics Technology (Changzhou) Co., Ltd. integrates high-precision current detection, over-current alarm, and temperature sensing into a single compact unit. It offers four key advantages:

• Intelligence: Equipped with integrated current monitoring, it enables active disconnection driven by the BMS under abnormal current conditions.

• Integration: Multiple functional components are consolidated into a small form factor, simplifying system layout.

• Cost Efficiency: Reduces overall component and system costs, including busbar, wiring, and installation expenses.

• Enhanced Safety: Provides high short-circuit resistance and reliable high-current breaking capability, ensuring system safety.

Widely applicable in automotive, charging/swapping infrastructure, and energy storage systems, the product has successfully passed bench testing at a European automotive components supplier.

Eddy Current Sensor

The eddy current sensor utilizes the eddy current effect generated in metal objects within an alternating magnetic field. Through its built-in transmitter and receiver coils, it enables precise detection of target angles and linear positions. With advantages such as high-speed measurement, exceptional accuracy, strong anti-interference capability, compact size, and flexible installation, it is widely applied in new energy vehicle systems including e-drive motors, braking systems, and chassis steering systems.
