Four-chemical
emitting element

Double coupling lens

APC circuit

New Advanced sensor with Visible Indicator

Stable sensing over
long and short periods

In addition to a ‘four-chemical emitting

element’ which suppresses changes in the

light-emitting element over time so that a
stable level of light emission can be
maintained over long periods, a new ‘Auto
Power Control (APC) circuit’ has also been
adopted. Because fluctuations over short
periods of time have also been suppressed,
stable sensing is possible very quickly once
the power is turned back on after setup
changes.

Independent dual outputs

Largest number in the industry! Automatic interference
prevention of up to 16 units

Two independent output channels are provided, so that one sensor
can be used for control tasks that previously required two sensors. In
addition, the second output channel can be used for simple self­diagnosis and alarm output, so that ease of maintenance is improved.

Can be used even in places where fibers need to be installed
close together.

Industry first! Light-emitting amount selection function

If the light-receiving level becomes saturated during close-range sensing or when
sensing transparent or ultra-small objects, you can adjust the light-emitting amount
of the sensor to stabilize sensing without needing to change the response time.
Sensing that previously required the response time or fibers to be changed can now
be set much more easily using this function.

High-speed response 65 ¨s

High-speed response that is about twice as fast as before has
been achieved. Even small objects moving at high speeds can be
sensed. In addition, interference between two units is prevented in
high-speed mode (H-SP).

Industry’s largest display 9999

Industry’s largest display with 4 digits (9999). With a greater difference
in digit value than previous models, threshold values can be set in units
of 1 digit up to maximum 9999. Threshold setting can now be done
more easily and accurately.

When the interference prevention function ‘ ’ is set, the number
of mountable fibers becomes double. Furthermore, take care that
the response time also becomes double.

When the power supply is switched on, the light emission timing is
automatically set for interference prevention.
