The adoption of a unique large lens allows
even thin glass substrates to be sensed
directly from the side. In addition, because
the sensing range is wide (2512.5 mm
0.9840.492 in), stable mapping is
possible even if glass substrates are in
irregular positions.
Accurate mapping even for thin glass substrates
Minor modifications allow sensing range to
be further increased so that even more
stable and high-precision alignments are
possible.
Increased sensing performance
Increases in sizes of glass substrates
mean greater amounts of flexure, but a
single fiber can sense glass even if
horizontal flexure is within 8 (previously
6).
Large light amounts can be obtained for a
variety of glass edge shapes such as R
surfaces and C surfaces, so that accurate
mapping of glass substrates inside
cassettes is possible.
Glass that has received black or yellow
masking can also be sensed in addition to
clear glass.
Can be used for a variety of glass substrates
A compact size of W25H30D7.3 mm
W0.984H1.181D0.287 in allows
installation to the ends of robotic hands. In
addition, the adoption of a resin case
means weight is light at about 39 g.
Light and compact
Stable sensing is possible over even
longer sensing ranges.
In addition, the fiber will not detect a glass
substrate 30 mm 1.181 in or more away
achieving outstanding detecting
characteristics for limited distance.
Sensing range 0 to 23 mm 0 to 0.906 in
A sensing range of 3 to 17 mm 0.118 to
0.669 in (previously 5 to 17 mm 0.197 to
0.669 in) and a positioning error of 0.2 mm
0.008 in or less makes higher precision
sensing possible.
Longest sensing range
in the industry for
seating confirmation.
Sensing is even
possible if absorption
pads are presented.
Sensing range 0 to 7 mm 0 to 0.276 in
Independent, large-scale lenses is built-in.
Large amounts of light can be received,
enabling stable sensing even of glass
substrates that have been colored (with
low reflectivity) by their treatment
conditions.

Sensing object (Glass substrate)
Sensing enabled from 0 mm 0 in
Ultra-thin and compact size, so takes up
less space for mounting.
Also, the center of the beam axis and the
center of the mounting hole are directly
aligned rendering system designing simple.
