Murphy VS94 （20700063）：沖擊和振動(dòng)控制開關(guān)
VS94 (20700063): Shock & Vibration Control Switch
VS94 沖擊和振動(dòng)控制開關(guān)，采用 NEMA 4/4X 玻璃填充聚酯外殼 （20700063）
VS94系列是一種機(jī)電設(shè)備，旨在保護(hù)設(shè)備免受破壞性沖擊或振動(dòng)。這種靈敏的機(jī)制可以檢測(cè)到過(guò)度的沖擊或振動(dòng)，并在發(fā)生進(jìn)一步損壞之前關(guān)閉設(shè)備。一組觸點(diǎn)通過(guò)磁性閂鎖機(jī)構(gòu)保持在閉鎖位置。隨著沖擊或振動(dòng)水平的增加，慣性質(zhì)量對(duì)閂鎖臂施加力并迫使其遠(yuǎn)離磁性閂鎖，導(dǎo)致閂鎖臂分離并操作觸點(diǎn)。通過(guò)調(diào)整磁鐵和閂鎖臂板之間的氣隙量來(lái)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(xiǎn)場(chǎng)所的應(yīng)用。
VS94 型號(hào)的額定電壓高達(dá) 480 VAC。 （有關(guān)可用的型號(hào)和選項(xiàng)，請(qǐng)參閱如何訂購(gòu)。
VS94 的應(yīng)用包括所有固定類型的機(jī)械或設(shè)備，在這些機(jī)械或設(shè)備中，過(guò)度的沖擊/振動(dòng)可能會(huì)造成損壞或?qū)φ２僮鳂?gòu)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
