A-20GQ limit switches are widely used in a variety of tasks, from simple operations to complex processes. These switches are known for their reliabiliy, durability and accuracy. In this article, we will discuss the application field and working principle of A-20GQ limit switches.

Application Field

A-20GQ limit switches are primarily used in the industry for instance, in machine tooling and in process control applications. These switches can detect the presence or absence of an object, such as a tool or part, and send a signal to a machine or system. Typically, A-20GQ switches are used to trigger machine operations when an object reaches a certain position, such as when a part enters or exits a machine. They can also be used in conveyor systems to indicate when items of a certain size or shape pass along the conveyor.

Another significant application for the A-20GQ limit switch is in safety systems. These switches can be used to detect when a dangerous situation is occurring, such as when a machine has stalled or become overloaded. The presence of an overload or insufficient supply of power can be detected and the switch will send a signal to the safety system to shut down the machine.

Working Principle

The A-20GQ limit switches are easy to install and operate. They are available in two main types: snap action and limit switches. Snap action switches rely on a compression spring to perform their function, while limit switches use a plunger or other mechanism to make contact with the target.

The basic working principle of the A-20GQ limit switch is the same for both types. When a target object reaches the switch, the contact is made and the switch will send a signal to the control unit or safety system. The signal can be in the form of a voltage, current or other form of data, depending on the system and application.

The A-20GQ switches have a number of features that make them attractive for industrial applications. They have a long service life and are resistant to shock and vibration. The units are extremely reliable and are UL and CSA approved.

The A-20GQ switch is designed for use in a variety of environments and can be installed in damp or wet locations. If necessary, the enclosure can be sealed to protect the switch from water or other liquids. The units are available in both stainless steel and plastic housings.

Conclusion

The A-20GQ limit switch is a reliable and durable switch that is suitable for a variety of industrial applications. The switch is available in two types: snap action and limit switches. The unit is easy to install and operate, and is resistant to shock and vibration. The switch is UL and CSA approved and can be used in damp or wet environments. With its wide range of features, the A-20GQ limit switch is a great choice for any industrial setting.
