2 Sets Magnetic Reed Switch DC12 to 24V NC Wired Door Window Sensor for Home Security Alarm Systems

Feature: 1. Reliable Material: Made of iron, the door window switch housing is robust and reliable. It features a high temperature and deformation resistant leaf switch, ensuring the longevity of the sensor. 2. Normally Closed (NC): The circuit is switched on (light is on) when the switch is near the magnet, and the circuit is switched off (light is off) when the switch is separated from the magnet, providing easy and efficient control. 3. Transmission Distance: With a transmission distance of 10‑20mm, the contacting point of the magnetic switch reacts quickly and detects accurately, ensuring effective operation. 4. Working Conditions: Designed for a voltage range of DC 12V‑24V when the magnetic door is powered. The load current should not exceed 100mA, thus maintaining safety and efficiency. 5. Wide Application: The magnetic door switch is suitable for all access control and anti theft alarm systems. It can be installed on wooden or aluminum alloy doors and windows, catering to a variety of needs. Specification: Item Type: Magnetic Door Switch Set Material: Iron Connection Method: Normally Closed (When the door switch is closed, it is in a conducting state) Rated Voltage: DC12-24V Package List: 2 x Pairs of Magnetic Reed Switch
