Snap Action, Limit Switches - D3V-64M-2C24 Application Field and Working Principle

Snap action, limit switches refer to industrial mechanical switches designed to turn ON and OFF electronically controlled circuits when reached a particular physical location. The D3V-64M-2C24 is a reed switch-based snap action, limit switch by Omron, a well-known industrial controls manufacturer. Even though a reed switch is a normally open type switch, the D3V-64M-2C24 is a SPDT (single pole double throw) switch that includes a “pull open” feature, allowing it to act as a normally closed (NC) switch.

Application Field

The D3V-64M-2C24 is primarily used for industrial applications where reliable open-closed switching is a must. Some common applications include: industrial machinery, motorized doors and gates, automatic water tanks and level control, switch boards, and manufacturing machinery. The D3V-64M-2C24 is commonly used in these applications because its design is highly reliable, accurate, and low cost when compared to other types of switches.

Working Principle

The D3V-64M-2C24 is a reed switch-based snap action, limit switch. Reed switches are small cylindrical tubes made out of a glass-like material and filled with a non-corrosive gas. Inside these tubes, there are two magnetic, spring-loaded components, such as a reed armature and a ferromagnet. When an external magnetic field is applied, the spring-loaded components will be attracted to the magnet, thereby closing the circuit. Releasing the external magnetic field will cause the spring-loaded components to open the circuit.

The D3V-64M-2C24 is more advanced than a basic reed switch in that it includes a “pull open” feature, which allows it to act as a normally closed (NC) switch. The “pull open” feature is a type of spring mechanism that can force the switch contacts open, allowing the switch to act as a NC switch. When the external magnet is released, the spring mechanism will force the contacts open and turn the circuit off. This feature makes the D3V-64M-2C24 an incredibly useful switch for when a NC type switch is required.

Conclusion

The D3V-64M-2C24 is a reed switch-based snap action, limit switch by Omron with a built-in “pull open” feature, making the switch suitable for use as a normally closed (NC) switch in industrial applications. The D3V-64M-2C24 is used frequently in various industrial applications, such as industrial machinery, motorized doors and gates, and automatic water tanks and level control.
