MAGNETIC REED SENSOR

The magnetic reed sensor is a contactless switch that operates using a magnet. It consists of two thin metal reeds inside a sealed glass tube that close when exposed to a magnetic field. The sensor provides a simple on/off digital output, making it ideal for security systems, door/window sensors, and automation projects. It is widely used in burglar alarms, position sensing, and proximity detection. The reed sensor has a long lifespan due to its contactless operation. It operates with low power consumption, making it suitable for battery-powered applications. The module is available in normally open (NO) and normally closed (NC) configurations. It is commonly used in automotive applications and industrial machinery for position sensing.
