Murphy VS94 （20700063）：沖擊和振動控制開關
VS94 (20700063): Shock & Vibration Control Switch

VS94 沖擊和振動控制開關，采用 NEMA 4/4X 玻璃填充聚酯外殼 （20700063）

VS94系列是一種機電設備，旨在保護設備免受破壞性沖擊或振動。這種靈敏的機制可以檢測到過度的沖擊或振動，并在發生進一步損壞之前關閉設備。一組觸點通過磁性閂鎖機構保持在閉鎖位置。隨著沖擊或振動水平的增加，慣性質量對閂鎖臂施加力并迫使其遠離磁性閂鎖，導致閂鎖臂分離并操作觸點。通過調整磁鐵和閂鎖臂板之間的氣隙量來獲得靈敏度。

VS94 系列安裝在 NEMA 4/4X 玻璃填充聚酯外殼中，并具有底座安裝座。它適用于非危險場所的應用。

VS94 型號的額定電壓高達 480 VAC。 （有關可用的型號和選項，請參閱如何訂購。

VS94 的應用包括所有固定類型的機械或設備，在這些機械或設備中，過度的沖擊/振動可能會造成損壞或對正常操作構成威脅：

VS94 (20700063): Shock & Vibration Control Switch

VS94 Shock & Vibration Control Switch In A NEMA 4/4X Glass Filled Polyester Enclosure (20700063)

VS94 Series is an electro-mechanical device designed to protect equipment from damaging shock or vibration. This sensitive mechanism can detect excessive shock or vibration and shut down the equipment before further damage occurs. A set of contacts is held in a latched position through a magnetic latch mechanism. As the level of shock or vibration increases, an inertia mass exerts force against the latch arm and forces it away from the magnetic latch causing the latch arm to separate and to operate the contacts. Sensitivity is obtained by adjusting the amount of air gap between the magnet and latch arm plate.

The VS94 Series is housed in a NEMA 4/4X glass-filled polyester enclosure and has a base mount. It is for applications in non-hazardous locations.

VS94 models are rated up to 480 VAC. (See How to Order for models and options available.)

Applications for the VS94 include all stationary types of machinery or equipment where excessive shock/vibration can be damaging or poses a threat to normal operations in:

Cooling fans
Pump jacks
Pumps
Engines
Compressors
Rotating and Reciprocating Machinery
