Application Field

The D4NL-4CFG-B-NPT Snap Action, Limit Switches are suitable for a wide range of applications, such us industrial automation, machine tools, motor control, robots, vending machines, and door interlocks, among others. They are also a great choice for applications where space is limited, such as compact equipment, where its small profile allows for easy installation in even the tightest of places.

Working Principle

When the plunger of the D4NL-4CFG-B-NPT Snap Action, Limit Switches is actuated, an electrical circuit is opened or closed by the switch, depending on the specific application. This is the basis of the working principle of these switches, which is very simple yet highly reliable.

The plunger is operated by mechanical means, such as a lever, cam, or other mechanical device. When this is actuated, it travels until it contacts the electrical contacts on the switch body. This creates an open or closed circuit, depending on the specific configuration.

The switch is equipped with a durable actuator, making it highly resistant to mechanical shock and vibration, which is often a factor when installed in high-vibration environments. Additionally, the electrical contacts are securely protected in rugged housings to ensure continued operation under the harshest of conditions.

Conclusion

The D4NL-4CFG-B-NPT Snap Action, Limit Switches are a reliable, durable switch solution for any application. Their plunger design allows for reliable on/off limit switch operations in even the harshest environments, and their small profile makes them a perfect solution for spaces where space is at a premium. Finally, their UL listing, FM approval, and CSA certification provide confidence in the quality and safety of using this switch in your application.
