Description
K-LC5 is an extended range dual channel
Doppler Radar module with an asymmetrical
beam for short distance sensors. It is ideally
suited for person movement sensors.
Dual IF I and Q allow movement direction
detection and high performance signal
processing. FM input allows FSK ranging
applications.
An extremely slim construction with only 6mm
depth gives you maximum flexibility in your
equipment design.
Powerful starterkits with signal conditioning
and visualization are also available. (see
