Sensor specialist Baumer presents new laser sensors for detecting the smallest objects. They enable even greater precision when detecting the smallest differences in position and gaps as well as small parts with a diameter of just 0.05 mm.
According to Baumer, compact machine designs with limited space, detection of very small objects, narrow gaps or precise triggering at fast cycle rates are just some of the areas of application for the new optical O200 miniature sensors with focussed laser light beam.
Precise detection of the smallest objects
Thanks to their unique range of 180 mm, the O200 laser variants with background suppression are suitable for the precise, pinpoint detection of the smallest objects in the material feed, for example. A minimum jitter of less than 20 microseconds ensures maximum reproducibility and thus enables highly accurate triggering. In the packaging industry, for example, a Tubular bag cut to fit perfectly can be used. This reduces material waste.
With their low weight and small size, the O200 laser sensors also provide the necessary agility for grippers. Thanks to the extra power reserves (high-power mode), they also recognise deep black or angled objects, even at large distances of up to 180 mm.
In addition to the laser dot variants, the portfolio also offers sensors with a 56 mm long laser line. The sensors detect a much wider area and thus compensate for smaller punched-out areas or holes, such as on printed circuit boards. O200 laser retro-reflective photoelectric sensors with single-lens optics can reliably detect objects even through very small openings thanks to the transmitter and receiver beam on one axis. This enables even more Flexibility in machine design.
Laser sensors with added value
Thanks to their high precision, the sensors offer a new level of Safety and reliabilityt in detecting even the smallest objects and gaps. This minimises downtimes due to false detections. In addition, system efficiency can be increased thanks to increased product cycle times through fast and precise triggering. A compact design and the wide range of variants increase the flexibility of the machine design. According to the company, CAD data with an integrated beam path also reduces the design-in effort required to optimise the design. Protective measures against extraneous light are not required.
