2-channel radio key transmitter Type: RNK-02 EXF10000024

Radio key transmitter for smart home

This 2-channel radio key transmitter RNK-02 is an element of the Exta Free system, which allows for wireless control of various devices in your home. Thanks to it, you can conveniently turn lights on/off, dim them, raise and lower blinds, and even set schedules. The device is particularly useful in renovations where running additional cables is difficult or impossible.

Versatile application and easy installation

Small size and no need for external power supply make it possible to mount the transmitter practically anywhere – on glass, wood or plaster. Installation is simple and does not require specialized tools – just double-sided tape or a few screws. Therefore, both installers and end users will appreciate its ease of use. The device is ideal for residential buildings, offices or other facilities where remote control of lighting and other devices is needed.

Reliability and comfort of use

The RNK-02 transmitter offers a long operating range – up to 250 meters in open space. Optical signaling informs about sending the signal and battery status (CR2032), which ensures comfort of use and avoids unexpected situations. The ability to independently control two receivers increases the functionality of the device, and compatibility with other elements of the Exta Free system allows for future expansion of the installation. The operating range may be reduced by obstacles such as brick, concrete or metal – therefore, it is worth taking this into account when planning the installation. Additionally, using the RTN-01 repeater allows you to increase the signal range in difficult conditions.

The device is characterized by a rated supply voltage of 3V DC and works with a CR2032 battery with an estimated life of 3 to 5 years. It operates at a frequency of 868 MHz and has two control channels. The operating range is up to 250 meters in open area, and the degree of protection is IP20. The operating temperature is in the range of -10°C to +55°C, and the dimensions of the device are 90 x 80 x 11.5 mm with a weight of about 38 g. Transmission is one-way with addressing.

The device meets the standards PN-ETSI EN 300 220-1 and PN-ETSI EN 300 220-2 and has a CE mark. This is a guarantee of safety and compliance with applicable regulations.
