WEB CUTOFF REGISTRATION

Objective:

To detect a color mark printed on a continuous web
for accurate control of downstream cutoff.

Sensor: SME312CVB

Operation:

MINI-BEAM

Expert

Model SME312CVB is a convergent

mode sensor with a blue light source that reliably detects
many difficult color mark contrasts, such as yellow against
off-white (shown here). The sensor is located near the
printing drum, where web “flutter” is not a factor. The
MINI-BEAM should be mounted at a “skew” angle of about
15 degrees from the perpendicular to shiny or clear webs in
order to avoid strong direct reflections of the sensing beam.
The MINI-BEAM

Expert

is available in fixed-wavelength

models with blue, green, or red light sources for handling
specific color contrasts.

WAFER CASSETTE PRESENCE

Objective:

To sense the presence of wafer cassettes on a conveyor.

Sensor: SME312FP with PIT46U fibers and L2 lenses

Operation:

Silicon wafers are transported in cassettes from one
location to another on a conveyor. Individual plastic
fiber optics are located on both sides of the conveyor
in the opposed sensing mode. L2 lenses are fitted onto
each fiber sensing tip to extend sensing range. The beam
is broken whenever a cassette is present.

CLEAR BOTTLE COUNTING

Objective:

To reliably count clear bottles moving on a high-speed
conveyor line.

Sensor: SME312LPC

Operation:

The polarized retroreflective optics of MINI-BEAM

Expert

clear object detection sensors are optimized

for reliable sensing of clear glass or plastic materials.
This sensor generates one solid count from each
bottle moving through the beam.
