    • About this item

  • 15mm Sensing Distance: With a working distance of approximately 15mm ±5mm, these window door sensors accommodate common installation scenarios for doors, windows, cabinets, and more. These window door sensors' sensitivity ensures consistent operation when the magnet and switch align correctly.
  • NC Magnetic Sensors: These door and window sensors use a normally closed magnetic switch configuration, making these door and window sensors suitable for connecting directly to GND and N.C ports of most wired or wireless alarm control panels. These sensors offer simple, effective perimeter protection with minimal setup.
  • No External Power Required: The door sensor system operates without the need for an external power supply, relying solely on the circuit path created between magnet and switch. This makes door sensor system a practical and efficient choice for DIY installations and low-maintenance security systems.
  • Durable Magnetic Switch Build: Each magnetic switch is constructed to withstand up to one million operational cycles, with a switching voltage of 100VDC and a 300mA load current. This durability makes them a dependable long-term addition to any security setup.
  • Installation Notes: For best performance, avoid mounting these magnetic door sensors on iron or magnetic surfaces, which can weaken the magnet’s effectiveness. Ideal for use on wood, plastic, or non-metallic doors and frames. Screws or adhesive (not included) may be used for secure mounting.
