Magnetic door sensors, also known as reed switches, are essential components in home and commercial security systems, offering reliable protection against unauthorized entry. Their simple yet effective design has made them a popular choice for securing doors, windows, and other entry points. This comprehensive guide will delve into the world of magnetic door sensors, exploring their functionality, benefits, and practical applications.
Magnetic door sensors comprise two main components:
When a magnet is brought into close proximity to the reed switch, the reeds become magnetized and align with the magnet's field. This alignment completes an electrical circuit, triggering a signal that indicates the door or window has been opened.
Magnetic door sensors are commonly used in various applications, including:
When selecting magnetic door sensors, consider the following factors:
