Understanding Safety Door Limit Switches and Traditional Door Sensors

1. What is a Safety Door Limit Switch?

A Safety Door Limit Switch is a device that ensures a door is in the correct position. It helps in detecting whether the door is open or closed, thereby providing a safety measure that can prevent accidents. These switches are often used in industrial settings and automated systems where precision is critical.

2. What are Traditional Door Sensors?

Traditional door sensors, on the other hand, are devices that detect the presence of a door and provide information on whether it is closed or open. They often use infrared, magnetic, or pressure-based technology to achieve this. These sensors are common in security systems and can be found in various residential and commercial applications.
