Miniaturization by using single chip optical IC
The beam-receiving photodiode and
the A/D conversion circuit have been
fabricated on a single chip optical IC
(full custom). Hence, in spite of its
miniature size, it has a performance
and reliability which is equal to or
better than the conventional product.
Incorporates a sensitivity adjuster even in this size
The sensor incorporates a sensitivity
adjuster in spite of its miniature size.
It is convenient when you need ne
adjustment. Further, the receiver of the
thru-beam, side sensing type sensor
incorporates an operation mode switch
which can change the output operation.

Long sensing range
The EX-20 series achieves long distance sensing [thru-beam
type: 2 m 6.562 ft, retroreective type: 200 mm 7.874 in (when
using the attached reector), diffuse reective type: 160 mm
6.299 in], despite its miniature size.
Hence, it is usable even on a wide conveyor.
BASIC PERFORMANCE
Clear beam spot using red LED dot light source
The emission area of a dot light source is smaller than that
of a conventional LED at light source, and it is possible to
design a high power, narrow beam. Since a red LED dot
light source is used, the red beam spot is clear even at a far
place, so that alignment and conrmation of sensing position
is easy. Further, since the thru-beam type, too, incorporates
a visible narrow beam, it can also reliably detect small parts,
such as, chip components, lead frames, etc.
