UHF Code-Hopping Data Transmitter secures wireless control links
03 July 2008
Radiometrix announces the release of the KTX2 code-hopping data transmitte, designed to provide secure wireless control links.
The Radiometrix KTX2 is a miniature PCB mounting UHF radio transmitter module with onboard code-hopping encoder designed to provide secure wireless control links in a variety of industrial/commercial applications. Operating at 315MHz, 433.92MHz or 434.42MHz, it offers engineers a usable range of up to 75m in-building or 300m over open ground. Each transmitter module is pre-programmed and unique. The 32-bit encryption level creates more than 4 billion hop-codes for security, whilst four control lines allow up to fifteen user defined controls to be transmitted. Designed to be used with the company’s KRX receiver-decoders, it is a crystal controlled PLL based transmitter with 2mW RF power output (10mW version also available) in a module format allowing OEMs to integrate it into their customised remote controller. The device is fully compliant with both EN 300 220-3 and EN 301 489-3 standards.
It can be employed in tasks such as automotive remote keyless control, building security, and unidirectional remote process control. Its compact dimensions (36.2 x 15.2 x 4.5mm) and low power consumption (1µA current during standby or 8mA while transmitting, from a 3 – 6V supply) make it particularly attractive for use in battery-powered keyless remote control products.
