UHF transmitter secures wireless control links
KTX2
Miniature PCB-mounting UHF radio transmitter module incorporates a code-hopping encoder with more than 4 billion unique codes.
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 315, 433.92 or 434.42MHz, it offers a usable in-building range up to 75m or 300m over open ground.
Each transmitter module is preprogrammed and unique.
The 32bit encryption level creates more than 4 billion hop-codes for security, and four control lines allow up to 15 user-defined controls to be transmitted.
Designed to be used with the company's KRX receiver-decoders, the KTX2 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 EN300-220-3 and EN301-489-3 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 (1uA 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.
