Accurate & reliable laser distance sensors

24 February 2020

The latest range of OM70 laser distance sensors from Baumer is designed to provide reliable, precise inline measurements, even on challenging surfaces and materials. They also include the latest connectivity options and fast analysis for quick and easy adjustment via the intuitive Baumer web interface feature.

Compared to other types of laser sensors, OM70 sensors feature one of the thinnest beam shapes, helping to ensure a more precise measuring focus. For example, most point type lasers typically only go down to 0.2mm x 0.75mm whereas the OM70 goes down to 0.05mm x 0.05mm. This feature optimises the sensor’s receiving array enabling it to fully exploit the information content and minimises measuring impairments caused by irregularities such as machining marks, tiny scratches or dents which can impair the performance of other types of laser sensors.

The range includes options which cover a wide range of measuring and sensor applications.  For example, the OM70 offers the highest precision at the closest ranges with precise inline measurement and a selectable range with a ‘sweet spot’ up to 250mm. This means reliable measurement regardless of the object thanks to its point and line beam shapes. A second option is available which ensures reproducibility of long distance measurements up to 1500mm.

Along with these is the OM70-T which provides tolerance measurement and dimensional accuracy checks, essentially an even more high performance option for the most demanding measuring applications.

This is crucial in helping to improve product quality with non-contact dimensional accuracy checks and can also be quickly adjusted to the measurement task using the integrated web interface.

The precise and reliable performance characteristics apply across the OM70 range. This means users have the confidence of unrivalled measurement, compared to other options available, particularly in the most challenging environmental conditions like poor ambient light, or dusty environments. For example, OM70 sensors have high ambient light immunity up to 28kLux whereas most other options only go up to 7.5kLux. In addition an automatic light adaption function which can power itself up means the sensors can see through dark or dusty environments and receive a stable reflection back. Finally, reliable results and measurements can be achieved, even on demanding surfaces, thanks to the extra fine line beam and stable measurement signals, thanks to functions such as automatic exposure control and adjustable filters.
