Installation instructions Baumer Installation instructions INFO You can find the suitable installation accessories on the Baumer website. Go to www.baumer.com for this. Then enter the item number of the sensor in the search field of the website. For measurement objects with shiny surfaces: Tilt the sensor 6 to 10° to the side so that the light directly reflected by the surface does not hit the receiver of the sensor. - Page 19 Prevent the detection ranges of the receivers from overlapping. Only the sensor’s own laser spot may be in the detection range of the receiver. ü û Mounting for round measurement objects: Align the sensor on the same axis as the measurement object to prevent reflections.
