磁性溫度開關(guān)技術(shù)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(dāng)溫度上升時，開關(guān)由OFF變?yōu)?/span>ON，則為NO常開型；當(dāng)開關(guān)由ON變?yōu)?/span>OFF時，則為NC常閉型。
2.動作溫度 Temperature
F30 – 130 ：以阿拉伯?dāng)?shù)字表示動作溫度，范圍為-30 ~ +130攝氏度。當(dāng)小于零度時，加前綴“F”，代表“負(fù)”。
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
