MC-38 Wired Door and Window Sensor Module

The Wired Door And Window Sensor Module – MC-38, commonly known as a magnetic reed switch, is used for detecting the open or closed status of doors, windows, or other objects. The normally open (NO) configuration means that the switch is open when the door is closed and closes (activates) when the door is opened, allowing it to signal an open 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 open configuration: closes when the magnet is away
• 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 Open)
• Contact Configuration: Normally open (NO)
• 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.

This door/window sensor modules are useful in detecting the state of doors, windows, drawers or cupboards. It can be easily interfaced directly to a microcontroller or an Arduino.

• Normally open reed switch
• Easily installed on doors, windows and drawers with screws
