433MHz Wireless Door Magnetic Sensor Detector Switch For Home Garage Entry Chime Alarm Security System

About This Product

If you want to know when a door or window opens, this little magnetic sensor has your back.

It's a wireless 433MHz detector that works with most alarm systems (just make sure your main unit supports it—it can't work alone).

The sensor is super simple: two pieces stick on the door and frame, and when they separate, it triggers the alarm.

Transmitting range is up to 100 meters in open areas, so it's plenty for most homes or garages.

It runs on one LR03 AAA battery (1.
5V, included) that lasts about 8 months, and the standby current is crazy low—only 10μA.

Installation is a snap with the adhesive backing; no screws needed.
Built from tough ABS plastic, it works in temperatures from -10°C to 40°C.

Great for entry doors, windows, or anywhere you want an extra layer of security.

Reliable, affordable, and easy to set up.
