Compared with mechanical switches, proximity switches have the characteristics of non-contact, spark free, noise free, reliable operation, long lifespan, low power consumption, high repeatability, fast response frequency, high operating frequency, and adaptability to harsh working environments. The company's proximity switches mainly include three types: KJDG series inductive proximity switches, KJH series Hall proximity switches, and KCG series magnetic reed proximity switches. Among them, cylindrical products have specifications such as φ 3, M4, M5, M8, M12, M18, M30, etc; Square products have specifications such as F5, F8, F16, F18, F22, etc.
