KJT All-metal proximity switch detects various metal objects, fast, no contact, extremely long life, reliable action, stable performance, fast frequency response, long service life, strong anti-interference ability, waterproof, shockproof, corrosion resistance and other characteristics . The integrated stainless steel shell including the sensing surface is absolutely free from any liquid or gas (cannot corrode stainless steel) during the entire working period. The material at the sensing surface is relatively thick, so it has better pressure resistance. The full metal housing makes them more mechanically resistant than traditional sensors. Therefore, it overcomes the weakness of traditional inductive sensors that are easily damaged.
