Radar sensors are not a specific brand but a category of devices used across various industries for detection, measurement, and monitoring. These sensors are produced by multiple companies worldwide, such as Siemens (Germany), Honeywell (USA), and SICK AG (Germany). They are widely used in automotive, aerospace, industrial automation, and security sectors. Key products include Doppler radar sensors, LiDAR systems, and proximity sensors, which enable applications like collision avoidance, speed measurement, and object detection. Companies like Banner Engineering and Pepperl+Fuchs also offer radar sensors tailored for harsh industrial environments.
