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 ﬁ 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, retroreﬂ ective type: 200 mm 7.874 in (when

using the attached reﬂ ector), diffuse reﬂ ective 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 ﬂ 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 conﬁ rmation 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.

If the incident light intensity level is such that the stability indicator lights up, stable sensing can be done without the light received operation and the light interrupted operation being affected by a change in ambient temperature or supply voltage.
