Baumer Ltd. Ultrasonic Proximity Sensor UNDK 09 (Beam Columnator)

Most ultrasonic sensors are based on the principle of measuring the propagation time of sound in the air. Ultrasonic frequencies outside the range of human hearing are emitted by the sensor. Sonic energy reflected by an object or target is picked up by the sensor’s receiver. The highly integrated and extremely powerful Baumer sensors are capable of sensing objects irrespective of their color, surface properties or transparency and of measuring the distance from the sensor to a target. Ultrasonic sensors are extremely resistant to dirt. They are not impaired by dust, smoke, vapors or other contaminants. Distance measuring sensors featuring a high resolution of 0.3 mm and measuring ranges of up to 2.5 m Proximity sensors; retro-reflective sensors; through-beam sensors starting from sugar cube size enclosures Fill level sensors for smallest containers capable of measuring fill levels in test tubes and even in microwell plates
