Big benefits in small-scale sensors

Miniature laser distance sensors with exceptional measurement performance are now essential 

Importantly, such sensors help manufacturers to meet the ever-present demands for optimum efficiency, in an age of increasingly compact machines and systems.

The new miniaturised OM20 and OM30 laser sensors available from sensing and instrumentation specialist BAUMER are said to be a good example, “being perfectly suited to handling precise measurement tasks, despite their ultra-compact size”, states the company.

Repeat precision

“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 37mm x 35mm x 13mm.”

For applications requiring measurements on structured surfaces, such as processed metal or wood, the OM30 option is described as an ideal solution, thanks to its line beam shape, with a range of up to 550mm. “The standardised IO-Link interface allows for easy integration into control systems along with simple parameterisation of the sensor.”

Illuminating features

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 illumination reserve of the sensor. The latter can also be used as an indicator for the soiling of the sensor, helping to support preventive maintenance regimes.

Another important characteristic highlighted is 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 28kLux, whereas most other options only go up to 7.5kLux.”

See-in-the-dark powers

An automatic light adaption function that 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, it is pointed out, thanks to the extra fine line beam and stable measurement signals, courtesy of functions such as automatic exposure control and adjustable filters.

 

The miniaturised OM20 and OM30 miniaturised laser sensors from BAUMER are well suited to handling precise measurement tasks.
