The door magnetic switch has a small size and is suitable for various door types 5.Wide range of use: suitable for installation and use of doors and windows in various fields such as urban security, banking, telecommunications, electricity, justice, residential areas, factories, companies, schools, homes, villas, warehouses, etc Product Principles The door magnetic switch is mainly composed of two parts: a switch and a magnet. The switch part is connected by a magnetic spring switch through a lead wire and packaged in a fixed shape; The magnet part is encapsulated in a plastic or alloy shell by a magnet with corresponding magnetic field strength. When the two are separated or close to a certain distance, it causes the switch to open and senses changes in the position of the magnetic switch of the object door Parameters: Model: RC-33 Embedded Door Magnetic Switch Wired Door Magnetic Alarm High quality imported ABS, imported dry reed tube 1007 #/24 # 300mm UL wire Action distance: 12MM plus or minus 5MM Switching withstand voltage: DC100V Load current: 80mA Normally closed: When the magnet approaches, it is conductive, and when the magnet leaves, it is a circuit breaker. Normally open: When the magnet approaches, it is closed (circuit breaker), and when the magnet leaves, it is a circuit breaker Appearance size: The diameter of the magnet part is about 10X14mm, and the diameter of the switch part is about 10x18mm Installation method: Concealed installation on wooden doors and windows or aluminum alloy doors and windows Attention: If the door magnet needs to be powered on, the voltage should be controlled between DC0-24V, and the power supply current should not exceed 1A. The load current should not exceed 150mA Package include: Package 1: Door magnetic switch * 1 Package 2: Door Magnetic Switch * 5 _x000D_
