K-LC6 is a dual channel Doppler Radar module with an asym-

metrical narrow beam for short to medium distance sensors.

Itisideally suited for person and vehicle movement and pre-

sencesensors.

This module includes an RF low noise amplier ( LNA ) for best

signal to noise performance. Dual IF I and Q allow movement

direction detection and high performance signal processing.

The optional internal IF amplier is available in version

K-LC6-RFB-01x.

An extremely slim construction with only 6 mm depth gives you

maximum exibility in your equipment design.

Powerful starterkits with signal conditioning and visualization

arealso available. ( ST100 / ST200)

OUTLINE DIMENSIONS Figure 3: Outline dimensions X2 X1 A P P L I C AT I O N N O T E S Sensitivity and Maximum Range The values indicated here are intended to give you a ‘feeling’ of the attainable detection range with this module. It is not possible to define an exact RCS (radar 4 cross section) value of real objects√σ because reflectivity depends on many parameters. The RCS variations however influence the maximum range only by 4√σ .

I N T E G R AT O R S I N F O R M AT I O N Installation Instruction Mechanical enclosure It is possible to hide the sensor behind a so called radome (short for radar dome) to protect it from environmental influences or to simply integrate it in the case of the end product. A radar sensor can see trough different types of plastic and glass of any colour as long as it is not metallized. This allows for a very flexible design of the housing as long as the rules below are observed. –– Cover must not be metallic.

United States (FCC) and Canada (ISED) This module has been granted modular approval for fixed and/or mobile applications. The modular approval allows the end user to integrate the module into a finished product without obtaining subsequent and separate FCC/ISED approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user’s authority to operate the equipment.

Europe (CE-RED) This module is a Radio Equipment Directive assessed radio module that is CE complaint and have been manufactured and tested with the intention of being integrated into a final product. According to the RED every final product that includes a radio module is also a radio product which falls under the scope of the RED. This means that OEM and host manufacturers are ultimately responsible for the compliance of the host and the module.
