D4N-1131

Snap action, limit switches are commonly used in a variety of industrial applications, and the D4N-1131 series is no exception. These small, reliable devices are popular for monitoring and controlling industrial machinery, especially in automated processes. Here is a look at their application fields and the working principle behind them.The D4N-1131 series is designed for a variety of industrial applications, including the safe stopping, starting, and reversing of machinery. They can also be used for signaling, positioning, and controlling operations. These switches are designed for a long operational life and are often used for long-term and high-criticality operations, such as pressure monitoring and valve/pump/motor control.The main feature of the D4N-1131 series is their high-sensitivity snap-action design. This means that they can sense and respond to very slight changes in pressure, temperature, or mechanical force. When the pre-set trigger point is reached, the switch snaps into place, prompting the control system to take the appropriate action. The force to move the switch can be set by the user, allowing for more precise control.The D4N-1131 series also has another notable feature: it is a non-contact switch. This means that the switch uses magnetic force to detect the trigger point, rather than physical contact. This increases the accuracy, as well as the durability, of the switch. It also makes them ideal for use in hazardous areas, where contact with volatile, or potentially explosive, materials is a hazard.The D4N-1131 series switches can be used in a wide range of applications, from complex machines in harsh industrial environments to delicate equipment in demanding medical and laboratory settings. The combination of strength, reliability and accuracy ensures that these switches will provide reliable operation for many years in any application.Finally, let’s take a look at the working principle of the D4N-1131 series switches. The basic principle is simple: a small plunger is pushed by a control system and the switch is triggered when the force of the plunger reaches the pre-set band. The plunger triggers a micro-contact snap action, which serves to activate or deactivate the circuit. The snap action relieves the plunger of the force so that it can reset itself and be ready to trigger again. This continuous operation repeats until the power to the switch is turned off.In short, the D4N-1131 series switches are designed for precise, reliable operation in a variety of industrial and medical applications. With their high-sensitivity, non-contact design, they are ideal for monitoring and controlling automated processes. They can also provide years of unrelenting performance for high-criticality operations.
