Door magnetic switch normally Closed

The Door Magnetic Switch, commonly known as a magnetic reed switch, is used for detecting the open or closed status of doors, windows, or other objects. The normally close (NC) configuration means that the switch is close when the door is closed (activate), and open when the door is opened, allowing it to signal a close door condition. This type of switch is commonly used in security systems, alarm systems, and automated door control systems.

Key Features:

• Magnetic reed switch for detecting door or window status
• Normally close configuration: closes when the magnet is close
• Compact and durable design
• Easy to install with adhesive backing or mounting screws
• Reliable and accurate detection of door or window positions

Technical Specifications:

• Type: Magnetic reed switch (Normally Close)
• Contact Configuration: Normally close (NC)
• Switching Voltage: Typically up to 100V DC
• Switching Current: Typically up to 0.5A
• Contact Resistance: Low, typically less than 100Ω
• Magnetic Activation Distance: Usually within 10mm to 25mm, depending on the strength of the magnet
• Operating Temperature Range: -10°C to +60°C
• Housing Material: Plastic or metal
• Size: Typically small, e.g., 40mm x 12mm x 8mm (varies by model)

Applications:

• Security alarm systems for detecting door or window status
• Home automation systems for monitoring openings
• Access control systems
• Industrial safety applications
• Appliance door status monitoring

Usage:

1. Mount the magnetic switch on the door frame or window frame.
2. Place the corresponding magnet on the moving part of the door or window.
3. Connect the switch to the alarm system or control system input.
4. Test the system by opening and closing the door or window to verify that the switch activates and deactivates correctly.
5. Adjust the position of the magnet if necessary to ensure reliable operation.

Caution:

• Ensure proper alignment of the magnet and reed switch for accurate operation.
• Verify the voltage and current ratings to ensure compatibility with your system.
• Avoid physical damage to the switch and magnet during installation and operation.
