施邁賽接近開關按其外型形狀可分為圓柱型、方型、溝型、穿孔（貫通）型和分離型。園柱型比方型安裝方便，但其檢測特性相同，溝型的檢測部位是在槽內側，用于檢測通過槽內的物體，貫通型在我國很少生產，而日本則應用較為普遍，可用于小螺釘或滾珠之類的小零件和浮標組裝成水位檢測裝置等。

SCHMERSAL接近開關接線圖
1）接近開關有兩線制和三線制之區別，三線制接近開關又分為NPN型和PNP型，它們的接線是不同的。請見下圖所示：
2）兩線制接近開關的接線比較簡單，接近開關與負載串聯后接到電源即可。
3）三線制接近開關的接線：紅（棕）線接電源正端；藍線接電源0V端；黃（黑）線為信號，應接負載。負載的另一端是這樣接的：對于NPN型接近開關，應接到電源正端；對于PNP型接近開關，則應接到電源0V端。
4）接近開關的負載可以是信號燈、繼電器線圈或可編程控制器PLC的數字量輸入模塊。
5）需要特別注意接到PLC數字輸入模塊的三線制接近開關的型式選擇。PLC數字量輸入模塊一般可分為兩類：一類的公共輸入端為電源0V，電流從輸入模塊流出（日本模式），此時，一定要選用NPN型接近開關；另一類的公共輸入端為電源正端，電流流入輸入模塊，即阱式輸入（歐洲模式），此時，一定要選用PNP型接近開關。千萬不要選錯了。
6）兩線制接近開關受工作條件的限制，導通時開關本身產生一定壓降，截止時又有一定的剩余電流流過，選用時應予考慮。三線制接近開關雖多了一根線，但不受剩余電流之類不利因素的困擾，工作更為可靠。
7）有的廠商將接近開關的“常開”和“常閉”信號同時引出，或增加其它功能，此種情況，請按產品說明書具體接線
