With a response time of just 1.3 ms, Baumer’s new ultrasonic sensor UNAM 12 comes very close to a photoelectric sensor. Twenty times faster than conventional ultrasonic sensors it is destined for highly dynamic processes. This, and the additional ability to detect very closely placed objects, leads to a considerable increase in efficiency. The device detects ultra-transparent packaging materials such as foils or bottles as well as wafers and glass in order to ensure a smooth process flow. For maximum reliability, the ultrasonic sensing principle guarantees faultless operation regardless of the degree of soiling. Versions with a special beam columnator feature a very narrow sonic beam to identify individual objects with even the smallest of operation distances. This narrow beam also allows the sensor to be mounted behind a protective wall and detect objects through narrow gaps. The sensor’s lateral accuracy is 0.5 mm.
