Optical sensing just got better
April 27th 2006 With a range up to 10m and two independent switchpoints, ifm electronic claims its new O1 sensor diffuse optical sensor is a huge technological leap. Traditional background-suppressed diffuse sensors won’t reach much beyond a couple of metres, but the company says this award-winning sensor is in a class of its own.
The breakthrough has been made possible by the award-winning, innovative PMD (photonic mixer device) chip, which combines time-of-flight measurement onto a single chip, making such a sensor compact and cost-effective.
The efector pmd, as it is known, uses a visible laser transmitter for easy sighting, accuracy and to achieve the long range. As the distance is actually measured, the effects of reflection from background can be ignored, making this, claims IFM, the longest-range background-suppressed sensor on the market today. The display will show the user where the switchpoints have been set, even in imperial units if required, and the pushbutton setting is straightforward.
Using an industry-standard M12 connector, this compact, robust sensor is suitable for standard industrial environments. IFM says it opens up a new world of opportunities in optical sensing.
