SDS004R Switches

Snap Action, Limit Switches

Snap action, limit switches are widely used in many industries due to their ability to provide cost-effective, accurate and reliable switching functions with a high degree of repeatability. The SDS004R is a widely used snap action and limit switch that is ideal for applications such as machine control, process monitoring and detection, automation, and security.

Working Principle

The SDS004R is a single pole, double throw switch that uses a spring and actuator to open and close the electrical contacts. The actuator moves the switch from its open position to its closed position when a predetermined force or pressure is applied. The same pressure or force must be applied to the actuator in order for the switch to move from its closed position to its open position.

When the switch is in its operating position, the actuator is engaging a stop arm which holds the contacts open. The spring, which is connected to the actuator, is responsible for providing the force required to move the actuator along its track. The moment the predetermined force is reached, the actuator springs into the "closed position," and the switch is activated.

The SDS004R is designed to be mounted in any position, allowing for flexibility when integrating the switch into a system. The switch can also be configured for either normally open or normally closed operation, depending on the application.

Application Field

The SDS004R limit switch is used in a variety of applications that require switching functions such as machine control, process monitoring and detection, automation, and security. It is often used as a failsafe measure that cuts power to a system when certain conditions are met, such as a limit being exceeded. This can help to ensure machine safety and is essential in many industrial processes.

The switch is also ideal for use in security systems, as it can detect the presence or absence of a pressure point, and has a high degree of accuracy. It can be used for door interlocking, security systems, and other applications that require a dependable switching mechanism.

The SDS004R is also suitable for use as a machine control switch. It is highly reliable and accurate, allowing for precise control of machines. It is commonly used for controlling the speed and position of moving parts, as well as for controlling the sequence of operations in automated processes.

In addition, the SDS004R is often used in process monitoring and detection applications. The switch can be used to detect the presence or absence of pressure, temperature, or other conditions that must be monitored in industrial processes. This allows the switch to be used as a safety feature that can shut down a machine if it detects an unsafe condition.

Conclusion

The SDS004R limit switch is a reliable and cost-effective solution for applications that require reliable switching functions. It is suitable for a wide range of applications such as machine control, process monitoring and detection, automation, and security. The switch is easy to install and can be configured for either normally open or normally closed operation, depending on the application.
