Snap Action, Limit Switches

The D4GL-4AFA-A is a type of snap action limit switch, which uses a dual–armature mechanism to actuate and detect mechanical action in response to certain conditions. The limit switch functions as an interface between an electrical connecting device, such as a circuit breaker, and an electrical load. It is designed to provide the user with reliable operation, durability, and safety while in operation.

Application Field

The D4GL-4AFA-A limit switch is ideal for a wide variety of industrial and commercial applications. These include automation, feeders, conveyors, elevators, material handling systems, safety systems, security systems, data logging, and maintenance systems.

The D4GL-4AFA-A is also used as an integral part of various machines, such as indexing tables, overhead doors, sorters, filling machines, and repair tools. It can also be used in laboratory and laboratory testing systems.

Working Principle

The D4GL-4AFA-A limit switch consists of two interconnected armatures, which create an electromechanical connection. When a change in condition is detected, the internal contact points open, breaking the electrical connection and preventing any current from flowing. As the armature continues to move, the contact points close, reactivating the circuit.

The D4GL-4AFA-A limit switch also incorporates an adjustable tension feature. This allows the user to control the switch’s sensitivity to various levels of pressure, ensuring the switch responds properly to changes in the environment. The user can also adjust the switch’s receptivity to noise, making it sensitive only to predetermined levels.

As its name implies, the D4GL-4AFA-A limit switch is quick and reliable in detecting and reacting to conditions that would otherwise require manual intervention. As a result, it reduces the time and effort associated with manual handling as well as improving the performance and reliability of the load.

The D4GL-4AFA-A limit switch is an essential tool for any industry dealing with electrical supplies, as it ensures safe and effective operation. It can act as an automatic switch for a variety of automated systems, ensuring the system is not overloaded or short-circuited. The switch is also useful in providing feedback to the operator, alerting them to any changes in the system.
