KMY24

www.DataSheet4U.com Microwave Motion Sensor KMY 24 Description The KMY 24 is a microwave rader motion sensor based on the Doppler effect. It transmits a low energy microwave radiation at 2.45 GHz which is reflected by objects. If the object is moving relative to the sensor, a Doppler shift occurs. The shifted wave is mixed with the original wave in two mixers, resulting in two output voltage signals. The phase shift between these two signals is negative or positive depending on whether the target is approaching or receding from the detector. Features High sensitivity Dual Mixers enabling direction detecting High reliability Low power consumption Low harmonic emission Small size Light weight Low cost Marking KMY 24 Ordering Code Operating Frequency Q62702-R323 2.45 GHz License No. BZT G127520H Typ KMY 24 Pin Configuration 1 2 3 4 − VS (GND) VD1 (output voltage D1) VD2 (output voltage D2) + VS SIEMENS KMY 24 Notes: 1 2 3 4 1. Solder pads must not be perforated, as this will damage, EHA07260 and may destroy the multilayer PC Board. 2. Regulations on the use of High frequency devices. The use of high frequency devices is regulated in most countries and certain frequencies can be subject to restrictions. The use of the KMY 24 should be clarified with the respective authorities in each country to ensure compliance with the prevalent legislation.
