D4N-9E72

Snap Action, Limit Switches

The D4N-9E72 snap action switch is an electrically operated switch that can detect the presence or absence of objects. These switches provide accurate and repeatable output when an object passes within the sensing range. They are typically used in a variety of applications, such as controlling the operation of motors and solenoids, sensing the position of objects, and monitoring temperatures, pressures, and levels.

Applications

The D4N-9E72 is commonly used in industrial automation, robotics, automotive and aerospace applications. The switch has a narrow, long sensing range and is designed for harsh environments. It can be used in a wide range of applications, including but not limited to:

• Monitoring the movements of objects
• Detecting the presence of parts on an assembly line
• Detecting the presence of fluids
• Measuring the progress of production
• Measuring the position of a component
• Detecting the position of a limit switch
• Monitoring temperatures and pressures in hazardous environments

Working Principle

The D4N-9E72 is a stand-alone device that is composed of two main parts: a body and a head. The body houses two switches, each with its own contact, and the head contains a sensing element. When a moving object passes through the sensing range, the contact inside the head closes, activating the switch.

The size of the sensing range can be adjusted using an external potentiometer. This allows the switch to detect objects of different sizes. The switch is rated for a maximum of 10A at 250VAC, 50/60Hz, making it ideal for controlling motors, solenoids, and other high-power applications. The contact is also rated for over 1 million cycles, ensuring the switch’s long-term reliability.

The D4N-9E72 is designed for harsh environments, and is UL and CSA certified for safety and quality assurance. Its housing is IP67 rated for dust and moisture protection, and its contact is made of stainless steel for corrosion resistance. The switch also features an LED indicator for easy troubleshooting.

Conclusion

The D4N-9E72 is a reliable and versatile snap action switch that is perfect for a variety of industrial and robotics applications. It is designed for harsh environments and offers repeatable and accurate output when an object is detected. Its adjustable sensing range allows for the detection of objects of different sizes, and its contact is rated for over a million cycles, ensuring its long-term reliability.
