Detecting presence versus absence may be rather straightforward but detecting slight differences in a shade of color is another matter. KEYENCE Corp. of America’s LR-W series can do both allowing it to address many sensing applications. The LR-W is capable of analyzing the full visible light spectrum. This capability allows photoeye standardization throughout a facility.
With its adjustable beam spot feature, the sensor provides stable detection even at a range of 500 mm. Packaged in a zinc die cast housing, the sensor does not require a protective cover and is also water resistant with an IP65/IP67 rating. It has a detailed digital display and a highly visible indicator.
