VS94 冲击和振动控制开关，采用 NEMA 4/4X 玻璃填充聚酯外壳 （20700063）

VS94系列是一种机电设备，旨在保护设备免受破坏性冲击或振动。这种灵敏的机制可以检测到过度的冲击或振动，并在发生进一步损坏之前关闭设备。一组触点通过磁性闩锁机构保持在闭锁位置。随着冲击或振动水平的增加，惯性质量对闩锁臂施加力并迫使其远离磁性闩锁，导致闩锁臂分离并操作触点。通过调整磁铁和闩锁臂板之间的气隙量来获得灵敏度。

VS94 系列安装在 NEMA 4/4X 玻璃填充聚酯外壳中，并具有底座安装座。它适用于非危险场所的应用。

VS94 型号的额定电压高达 480 VAC。 （有关可用的型号和选项，请参阅如何订购。

VS94 的应用包括所有固定类型的机械或设备，在这些机械或设备中，过度的冲击/振动可能会造成损坏或对正常操作构成威胁：

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
