The development of miniature laser distance sensors which provide exceptional measurement performance are a vital component in today’s more compact machines and systems, helping manufacturers to meet the ever-present demands for optimum efficiency. The new miniaturised OM20 and OM30 laser sensors available from sensing and instrumentation specialist BAUMER are a good example being perfectly suited to handling precise measurement tasks, despite their ultra-compact size.

These sensors are distinguished by their ability to provide reliable, surface-independent measurements with a repeat precision of up to 1µm combined with an impressive measurement speed of up to 5 kHz despite their miniature size. They measure just 37 mm x 35 mm x 13 mm.
For applications requiring measurements on structured surfaces such as processed metal or wood, the OM30 option is an ideal solution thanks to its line beam shape with a range of up to 550 mm. The standardised IO-Link interface allows for easy integration into control systems along with simple parameterisation of the sensor.
Apart from providing standard process data, such as the distance value or the signal quality, the sensors offer additional data including the measurement rate and the illumination reserve of the sensor. The latter can also be used as an indicator for the soiling of the sensor, helping to support preventative maintenance regimes.
The precise and reliable performance characteristics of these new miniature sensors apply across the entire Baumer OM sensor range giving users the confidence of unrivalled measurement, compared to other options available. This is particularly important in applications where the most challenging conditions prevail such as poor ambient light, or involve dusty environments. For example, OM70 sensors have high ambient light immunity up to 28 kLux whereas most other options only go up to 7.5 kLux.
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.
