1 Flame Retardant Material: The switch housing of the wired door window sensor is made from flame retardant ABS material. It features a high temperature and deformation resistant switch, making it strong for long term use. 2 Normally Closed (NC): When the switch is close to the magnet, the circuit conducts (the light is on); When the switch is separated from the magnet, the circuit is non conductive (light is off). 3 Transmission Distance: With a transmission distance of 10-20mm, this wire magnetic sensor ensures quick response and accurate detection. It offers both reliability and accuracy in its operations. 4 Appropriate Working Conditions: The sensor is designed to operate at a voltage of DC 12V-24V when powered. The load current should not exceed 100mA, ensuring safety and efficiency during use. 5 Wide Application: The wired door window switch is compatible with all access control and anti theft alarm systems. It can be installed on wooden or aluminum alloy doors and windows.
