1 Sturdy Construction: Made of brass shell material, the reed switch is resistant to high temperatures and deformation, making it highly reliable and sturdy, ensuring long lasting use. 2 Accurate Response: The magnetic switch features transmission distance of 10 to 20mm, featuring fast reflection and accurate detection, designed for superior accuracy and reliability. 3 Versatile Use: The door sensor swith is suitable for all access control and anti theft alarm systems, can be installed on wooden or aluminium alloy door and window. 4 Improved Control: Switch is normally closed design, the circuit is connected (light on) when the switch is near the magnet, and the circuit does not conduct electricity (light off) when the switch is separated from the magnet, ensuring reliable control. 5 Enhanced Performance: When the magnetic door is energized, the voltage is controlled at DC 12V to 24V, and the load current must not exceed 100mA. Red wire connects to the positive terminal, and white wire to the negative terminal.
