Snap Action, Limit Switches are used in a wide range of applications ranging from controlling motors and conveying systems to pressure and level monitoring. The 201EN9-RB format is a micro-switch that excels in applications requiring maximum durability and a high degree of shock resistance. This article will discuss the field of application and working principle of the 201EN9-RB.

Field of Applications

The 201EN9-RB is designed for environments where medium-to-heavy duty performance is required. Its superior design and construction gives it outstanding resistance to shock and vibration, making it ideal for a wide range of industrial and commercial applications. Examples of such applications include:

• Cooling and heating systems
• Ventilation systems
• Process control systems
• Manufacturing systems
• Auto industry
• Furnace switches
• Security systems
• Lifting devices
• Pressure & flow control systems
• Packaging machinery

The 201EN9-RB is capable of withstanding intense shocks caused by mechanical operations such as door slamming or reversed polarity. It is also designed to operate in wet or dirty environments. Furthermore, the snap switch actions make the device ideal for applications where fast response time is necessary.

Working Principle

The 201EN9-RB is a basic snap-action switch that uses a lever design to switch between the switch\'s two poles. The switch is activated when a current is supplied to its terminals. As the current moves across the terminals, the lever is rotated by an external force, causing the contacts to close and the switch to activate. The device is then considered to be "On".

When the external force is removed from the lever, the contacts open, and the switch is considered to be "Off". The switch is designed to operate with short electrical impulse lengths, so that once the amount of current applied is below a certain threshold the switch will automatically reset to "Off".

The 201EN9-RB is designed for high reliability, with mechanical life rated up to 10 million operations. The unit features a robust, robust brass or stainless steel body and silver alloy contacts, and is rated to operate over a wide temperature range of -40°C to +105°C.

Conclusion

The 201EN9-RB is a robust snap-action switch that is capable of withstanding shock, vibration and wet or dirty environments. Its reliable, robust design and long mechanical life make it an ideal choice for a wide range of industrial and commercial applications. Its fast operation and reset time make it suitable for applications requiring quick response time.
