Precision-engineered magnetic reed switch offers instant detection for doors/windows under 25mm gap. Waterproof IP54 rating allows stable performance in humid environments like basements or garages.

DIY installation requires no wiring – adhesive backing or screw-mount options included. Multi-scenario applications: secure smart homes, retail displays, warehouse equipment monitoring, or industrial safety triggers. Ships in bulk quantities with OEM customization available.
