Description

Wired magnetic door and window sensor that integrates directly with home alarm systems. The sensor uses a simple magnetic switch mechanism—when the magnet stays close to the switch, the circuit remains closed and inactive. When a door or window opens and the magnet separates from the switch, the circuit opens and triggers your alarm. Each sensor pair works without external power, connecting straight to the GND and N.C ports of your alarm control panel. The magnetic switch is rated for 15mm working distance and handles up to 300mA at 100VDC, with a lifespan of 1 million open-close cycles. The normally-closed output design means the sensor signals an intrusion the moment contact breaks. This pack contains 10 sensor pairs, enough to monitor multiple entry points throughout a home. Not recommended for iron doors, as metal interference reduces sensor sensitivity. Install on standard wood, composite, or aluminum doors and windows for reliable perimeter monitoring.
