磁性溫度開關技術說明 Description
1.觸點形式 Contact Form
NO: Normal Open 常開型,溫升閉合
NC: Normal Close 常閉型,溫升斷開
定義:當溫度上升時,開關由OFF變為ON,則為NO常開型;當開關由ON變為OFF時,則為NC常閉型。
2.動作溫度 Temperature
F30 – 130 :以阿拉伯數字表示動作溫度,范圍為-30 ~ +130攝氏度。當小于零度時,加前綴“F”,代表“負”。
3.安裝方式 Mounting Method
M14: 螺紋為M14*1.5
M16:螺紋為M16*1.5
1/2NPT: 螺紋為1/2-14NPT
D8:Φ8*30mm圓柱體,線長300mm
