A flexible cable type with greatly improved bending durability
compared to previous types is available. It is ideal for moving parts
such as robot arms.

The sensor is suitable for
detecting small and highspeed traveling objects.
High-speed response time: 0.5 ms
Thru-beam type sensor incorporated with an operation mode switch
on the bifurcation is also available. It helps you to test the operability
before start-up.

The EX-20 series achieves long

type: 2 m 6.562 ft, retroreflective
type: 200 mm 7.874 in (when
using the attached reflector),
diffuse reflective type: 160 mm

size.
Hence, it is usable even on a
wide conveyor.

EX-20SERIES
It can be tightened
with M3 screws.
Metal sleeve inserts have been provided in the mounting holes so
that the product is not damaged even in case of excess tightening.
A red LED dot light source is used to cast
a red spot beam so that the sensing
position can be checked easily.
Spots can be seen clearly
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.
