PoorHippo Magnetic Reed Switch – Normally Closed, 5m Wired Door Sensor For Garage Doors, Roller Shutters, Glass & Iron Doors (with Connector)

About This Product

Need a simple, reliable way to know if a door or window is open or closed?

This PoorHippo magnetic reed switch is a no-nonsense solution.
It's a normally closed (NC) wired sensor that comes with a 5-meter cable, so you've got plenty of length to run it back to your alarm panel or controller without needing extensions.

It's designed for all sorts of doors – garage doors, roller shutters, glass doors, wooden doors, and even heavy iron entryways.

Installation is genuinely easy – no technical degree required.
Just mount the two pieces (the magnetic part and the switch part) on the door and frame, run the wire, and you're done.

It's perfect for DIY security setups or automation projects.
The metal construction is tough too – it resists compression and erosion, so it holds up fine in garages, warehouses, or outdoor environments where weather and bumps are part of daily life.

The switch gives you stable, consistent performance over the long haul.

Use it to trigger lights, sound alarms, or just monitor entry points in your home or business.

It works with glass, wood, iron – basically any surface you can attach it to.
No fuss, no frills, just a solid sensor that does its job every time.
