K-LC5 is ideally suited for person detection and movement sensors.

K-LC5 comes with a new antenna design and an LNA input stage. The unsymmetrical antenna pattern is similar to our K-LC1a and K-LC2 devices.
K-LC5 is pin compatible with the K-LCx family.

IF outputs I and Q allow movement direction detection and high performance signal processing. I and Q processing is also very helpful for eliminating unwanted signals like vibrations and fluorescent light influences.

An extremely slim construction with only 6mm depth gives you maximum flexibility in your equipment design

A powerful starterkit with signal conditioning and visualization is available.

I/Q and LNA

Built in LNA RF preamplifier boosts the sensitivity of the dual channel K-LC5 to more than the level of a single channel transceiver (e.g. K-LC1a)
