carlo gavazzi瑞士佳樂接近開關回路的鐵質接近開關，首先24V是個開關量，中間要經過一個繼電器才到現場的接近開關，我就是想不通，以往我搞過的一般的限位開關，是24V-串聯在各各繼電器用，而24V+和另外一根線送到現場設備 是一個開關 這個我理解 可是接近開關呢 它又不是干接點 要有個回路才能工作的啊， 如果是24V+和-直接接到現場的 那繼電器不就一直是吸和的嗎接近開關分電感式、電容式，接線有三條的，有兩條的，電壓有24V、220V交流和直流的很多種；
  carlo gavazzi瑞士佳樂接近開關不管哪種，它們的工作原理都是接近物體后它里面的感應回路就產生一個電信號，它的放大電路放大這個信號后就輸出（開關）電壓，來啟動連在上面的中間繼電器動作
