Eltako FTKE-rw Wireless Window and Door Contact Sensor

The Eltako FTKE-rw is a highly efficient wireless transmitter assembly designed for window and door monitoring. This smart home sensor utilizes an integrated energy generator that creates power from lever pressure, meaning it operates entirely without batteries or connection cables. This eliminates standby loss and the need for periodic battery replacements. Measuring 48 x 32 x 12 mm in pure white, this compact device is versatile enough to monitor drawers and other moving facilities. It sends a radio telegram whenever the contact is opened or closed, providing reliable status updates for your home automation system. Installation is straightforward, as the unit can be attached via gluing, screwing, or using the included mounting brackets.
