ZV-NA2-2

ZV-NA2-2 Application Field and Working Principle

ZV-NA2-2 snap action limit switches are one of the most commonly used and versatile types of limit switches. As its name implies, these switches are pre-set to meet the needs of specific application fields and often used in various industrial automation processes.

These switches are highly versatile and can be used in a multitude of applications. Examples of such applications include sensing door, lid, and drawer closure, ensuring proper parts placement, actuating circuit breakers, and protecting against damage caused by overloads.

Mechanical Operation of the ZV-NA2-2

The mechanical design of the ZV-NA2-2 snap action limit switch allows it to actuate by using a snap action mechanism. This is accomplished through the use of an actuator push rod which is connected to the switch. As the actuator rod is moved, it causes the switch to move from the “off” to the “on” position. As the switch moves to the “on” position it causes a contact to open or close.

Electrical Operation of the ZV-NA2-2

The electrical operation of the ZV-NA2-2 is dependent upon the type of contacts used. If the switch is switched to the “on” position, it may either open or close depending on the type of contact used. If the switch is switched to the “off” position, then the contacts will open, thus resulting in an open circuit.

Environmental Protection

The ZV-NA2-2 snap action limit switch is designed to operate reliably in a wide range of environmental conditions. This includes temperature, moisture, and shock, as well as in hazardous locations subject to dust and other debris. The switch is designed to be resistant to corrosion and designed to maintain reliability and safe operation in high vibration and extreme temperature conditions.

Conclusion

The ZV-NA2-2 snap action limit switch is a highly reliable and versatile limit switch that is well suited for a wide range of industrial automation applications. Its snap action mechanism ensures reliable operation over a wide range of environmental conditions. In addition, its contact types make it suitable for either open or closed circuit applications which makes it an ideal choice for many industrial applications.
