Aeotec by Aeon Labs ZW120 ZW120-A Door/Window Sensor Gen5, Small, White

Aeon labs door/window sensor Gen5 is a battery-powered Z-Wave magnetic contact door/window sensor. The D/W sensor will send radio signals up to 5 associated Z-Wave devices within its own Z-Wave network when the main unit separates from the smaller unit (I.E. The door or window it is attached to is opened). bidirectional mounting plates and a push button release clasp allows for easy end-user installation. The Aeon labs D/W sensor also has tamper prevention capabilities and low-battery alerts. The sensor is 20% smaller than the first, and also includes the latest stable Z-Wave technology including Z-Wave explorer frames.
