and compact rectangular housing. Their large push button and easy-to-see indicators
provide easy configuration, alignment, and monitoring during use (see Figure 1 and

Retroreflective and Polarized Retroreflective Mode models are excellent for
sensing relatively small items where opposed-mode sensing is not possible. They are
recommended for relatively clean environments where high excess gain is not required.
Polarized models filter out unwanted reflections.
Polarized Retroreflective Mode – Clear Object Detection models reliably detect the
presence of clear objects.
Diffuse Mode models are excellent for sensing objects of adequate size and reflectivity
at short range. Divergent models are useful for sensing small items and translucent or
transparent materials at close range. The SME312DV sensors effectively sense specular
surfaces like semi-conductor wafers, disk drive media, glass and machined surfaces. The
collimated optics of the SME312DV also permits the sensor to be mounted against clear
container walls, view ports and other types of optical “feed-throughs.”
Convergent Mode models are a good choice for counting adjacent radiused objects and
for accurate position sensing. Blue, green and white beam models are recommended for
color mark sensing.
Glass Fiber Optic models are an excellent option for sensing in tight or otherwise
inaccessible areas. Fibers withstand vibration and shock and are immune to electrical
noise. Glass fibers withstand high temperatures, extreme moisture and corrosive
materials. Glass fibers are not recommended for applications requiring bending or
repeated flexing (see plastic fiber models). Visible beam models are recommended for
color mark sensing.
Plastic Fiber Optic models are an excellent option for sensing in tight or otherwise
inaccessible areas. Fibers withstand vibration and shock and are immune to electrical
noise. Plastic fibers function well at temperatures from –30 ° to +70 ° C (–20 ° F to
+158 ° F), and stand up to repeated flexing. Most are easy to shorten in the field, for
custom installations. Plastic fibers are not recommended for severe environments (see
glass fiber models). Plastic fiber optic sensors are recommended for color mark sensing.
