Uxcell 5-Pack Recessed Wired Security Door/Window Contact Sensor – Normally Closed Magnetic Reed Switch (RC-35), White

About This Product

These magnetic reed switches are a solid choice for DIY security setups or access control systems.

You get five sensors in this pack, each with a magnet and a recessed switch body that mounts flush into the door or window frame.

They're Normally Closed (NC), which means the circuit is conductive when the magnet is together – when the door opens and the magnet separates, it breaks the circuit and triggers your alarm panel.
Max actuation distance is about 15mm, and they handle up to 0.
1A at 200V DC.

The housing is white ABS plastic, and each switch comes with about 27cm of 24AWG wire.

Just a heads-up: these provide a switch signal only – they can't power a load directly, so you'll need to connect them to a proper alarm or access control system.

Great for home or business security.
