Abstract：To address the limitationsof traditional mechanical contactors in intellgent control systems，an intelligent contactless contactor based on the STM32 microprocessor has been designed and implemented.The STM32 is utilized as the core controller. Its 1/0 port resources and powerful embedded processing capabilities are utilized to construct a human-machine interaction interfaceand realizereal-timeacquisitionand processing of contactor control signals.Meanwhile，a passive filter circuit is designed to effctively suppresselectromagnetic interference，ensuring the system's stable operation incomplex electromagnetic environments.Electromagnetic compatibility（EMC） tests and impulse voltage withstand tests are conducted on core components.The test results show that it exhibits excelent control accuracyand stabilityunder various operating conditions，which can meet the design requirements.
