Titantek's torque wrenches are recommended for tightening coaxial connectors in order to obtain optimum repeatability and prolong connector life. They employ a "break" design so it is impossible to over-torque a coupled junction, and torque can be applied in either direction. 
Each MTJ torque wrench is factory preset to the proper in/lbs for tightening its coaxial connector type, and the color handles make it easy to select the correct wrench from your toolbox at a glance.

SMA 扭力扳手等同於 3.5 mm 扭力扳手嗎？

不，SMA 扭力扳手的結構不同於 3.5 mm 扭力扳手。他們形狀類似，但耦合扭力不同。

• 3.5 mm 接頭

  寬度與耦合螺帽扳手的平坦處相交叉：5/16"

  耦合扭力：90 N-cm (8 in-lbs)

• SMA 接頭

  寬度與耦合螺帽扳手的平坦處相交叉：5/16"

  耦合扭力：56 N-cm (5 in-lbs)

如要正確互連 SMA 公接頭與 3.5 mm 母接頭，請使用 SMA 扭力扳手。如要連接 3.5 mm 公接頭至 SMA 母接頭，請使用 3.5 mm 扭力扳手。

請注意，扭力扳手是用於標準的 3.55 mm 接頭。這和用於配有 3.55 mm NMD 式接頭的網路分析儀測試埠的扭力扳手不同。
