• What is magnetic door contact?

  as alarms to form a door and window monitoring system, achieving real-time monitoring of the status of doors and windows. In the field of smart home, Home Alarm Systems, door magnetic sensors are usually used in conjunction with smart door locks and other devices to effectively enhance home safety.

• 

• Door magnets are used to detect whether doors, windows, drawers, etc. have been illegally opened or moved. It consists of two parts: a wireless transmitter and a magnetic block. The door magnet is composed of two parts: a wireless transmission module and a magnetic block. There is a component called "steel spring tube" at the two arrows of the wireless transmission module. When the distance between the magnet and the steel spring tube is kept within 1.5 centimeters, the steel spring tube is in a disconnected state. Once the distance between the magnet and the steel spring tube exceeds 1.5 centimeters, the steel spring tube will close, causing a short circuit. When the alarm indicator light is on, it will emit an alarm signal to the host.

• What is a door magnet?
  

  A door magnet is a magnet and a switch that usually closes under the action of a magnet. After the door is opened and there is a certain distance from the magnet, the switch loses the force of the magnet and jumps open. Trigger a signal to the host. The difference between access magnet and access control:

  1. A door magnet is a small sensor used to detect whether a door is closed, and many electric locks come with a door magnet function. The security of the access control system is not only the security of the identification method, but also includes the security of the control system, software system, communication system, and power system. The entire system is a whole. For example, some fingerprint access control systems have an integrated controller and fingerprint recognition device, which should be installed outdoors. This way, the wire controlling the lock switch is exposed outdoors, making it easy for people to open it.

  
  

  2. Once the distance between the magnet and the steel spring tube of the door magnet exceeds 1.5 centimeters, the steel spring tube will close, causing a short circuit, and the alarm indicator light will light up while emitting an alarm signal to the host. Access control can effectively prevent external salespeople from entering the company and disrupting office order, and its practicality is relatively good. Working principle of door magnet:

  How to install the door magnet

  Installation method for door magnetic switch

  1. Select a wide gap switch for embedded installation.

  2. Drill installation holes for magnets horizontally at the outer edge of the door. Apply RTV fixing substance to the magnet. Then, insert the magnet into the hole. If a wide gap switch with bare magnet is used, the red end of the magnet should be pointed towards the outer side (the switch is sensitive to polarity).

  3. Remove the threshold.

  4. Fix the switch inside the threshold using RTV fixing material. Adjust its position so that it is directly below the magnet (and parallel) after the door threshold is installed.

  5. Install the door sill. Use an ohmmeter to test the switch for both open and closed doors. Connect the switch to the alarm circuit.

• The principle and working mode of door magnetic sensor

  A door magnetic sensor or Magnetic Alarm Contacts, is a contact type sensor typically composed of a switch body and a magnet. When the door is closed, there is an attraction between the switch body and the magnet, and the two fit tightly together. When the door is opened, the magnet and switch body will separate and disconnect, thereby changing the state of the switch body and outputting a door status signal.

  Door magnetic sensors are usually installed on the frame or door leaf of doors, with high sensitivity, fast response speed, and long service life. Door magnetic sensors can generally be divided into two categories: wired door magnetic sensors and wireless door magnetic sensors. Wireless door magnetic sensors are mainly used in fields such as smart homes.

  
  

  Application fields of door magnetic sensors

  Door magnetic sensors are widely used in security fields, smart homes, commercial buildings, and other places. In the field of security, door magnetic sensors can be connected to devices such.
