    FAQ

    1,Can inductive proximity switches sense stainless steel or aluminum alloy materials?
    The principle is that aluminum alloy or stainless steel can be induced, but the induction distance will decay, for example: the induction metal iron distance is 2mm, the induction aluminum alloy or stainless steel distance is 0.5mm.
    2, How to fix φ4φ3 without thread?   
    Usually fixed with glue or rivets
