Models
These sensors operate by detecting the reflection of their own light from
the object being sensed, and therefore require no special reflectors. "DSR"
models have better response than "D" models to objects within 3 inches of
the sensor. "DSR" models should be used when it is necessary to minimize
sensor response to background objects.
VALU-BEAM SM912CV and SM2A912CV visible red convergent sensors
(above) produce a precise .06" diameter sensing spot at a focus point 1.5" in
front of the sensor lens. Due to their very narrow depth of field, they excel at
detecting small objects only a fraction of an inch away from backgrounds.
They are also ideal for some high-contrast color-registration applications.
Their visible red sensing beam simplifies alignment.
Models SM912C and SM2A912C (below) are infrared convergent beam sensors.
Operating voltages, response times, repeatability, and focus distance are the same
as for the SM912CV and SM2A912CV. The SM912C and SM2A912C, however,
have much higher excess gain and an infrared sensing beam for highly reliable
sensing of objects of low reflectivity.
