D4GL-4FFA-A4-NPT

The D4GL-4FFA-A4-NPT is a limit switch belonging to the snap action family. A limit switch is a control device used to monitor physical movement of objects and is primarily used as protection and safety equipment. Limit switches are used on industrial production and automation systems to provide the operator with feedback concerning the safety and accuracy of the system in operation.

The D4GL-4FFA-A4-NPT is a micro switch designed for a variety of applications. It is suitable for controlling electronic relays, control circuits, and motor alarm circuits and is designed for use in dry or humid environments. Additionally, it features a wide variety of mounting configurations and a long minimum switching speed.

The D4GL-4FFA-A4-NPT features a standard snap-action, limit switch. Its arms (actuators) protrude from the switch’s body and must be manually depressed in order for the switch to be activated. When the actuator is depressed, the contacts open or close, depending on the design. This switching action is instantaneous and repeatable. The switch also has accuracy, which means it can perform operations up to 0.1 mm.

In terms of its construction, the D4GL-4FFA-A4-NPT is made up of a metal stator that houses an inner cartridge which is loaded with two contacts. These two contacts are connected by a nonmagnetic spring which has been preloaded to ensure that only a minimal amount of force is needed to cause the contacts to move. This means that a single motion is capable of switching the switch on and off.

Additionally, the D4GL-4FFA-A4-NPT is engineered with an anti-rotation feature, which allows the user to rotate the switch, while maintaining the same orientation. This is important as it eliminates the risk of misalignment of the contacts. Furthermore, the metal stator includes a protective cap to prevent dust and dirt from entering the switch and to protect the contacts in heavily vibrating environments.

The D4GL-4FFA-A4-NPT is also more precise than other limit switches due to its fast-travel design. This design allows the contacts to move with greater speed, which in turn helps the switch respond to changes quicker than other switches. This increases the accuracy of the switch and helps to ensure that the switch accurately responds to changes in conditions.

The D4GL-4FFA-A4-NPT can be used in many applications such as alarm systems, motor controllers, safety systems, position logic systems and motor control. It is suitable for dry, humid or dusty environments and has a wide variety of mounting configurations. It also features a long minimum switching speed and accuracy up to 0.1 mm. Overall, it is a reliable and precise limit switch suitable for a wide range of industrial applications.
