Enhanced teaching features (sensitivity setting) 

Full auto teaching

Simply pressing the button allows easy teaching of an
object moving at a high speed.
The teach hold feature allows indication of the
maximum and minimum data.

Auto teaching

2-point teaching with and without the presence of work,
allows the detection of slight level differences such as the
thickness of a piece of work and/or the presence of a film.

Positioning teaching

This feature is ideal for high-accuracy positioning that
requires accurate determination of a detecting point.

Maximum sensitivity setting

For applications requiring a “maximum” sensitivity setting
such as the detection of work with a through-beam type-
fiber optic cable. The incorporated extra powerful light
would allow use in an adverse environment.

Manual setting

Arbitrary manual increase and decrease of a set-point
level allows level setting while checking the operation.

Auto sensing function compensates for adverse environment

The level of received light is constantly monitored and
fluctuation is detected and automatically adjusts the
activation/deactivation level.
Stable detection at optimum sensitivity is ensured even if
the received light level frequently fluctuates due to dust or
water drops.

Manual hysteresis setting feature

The hysteresis can be arbitrarily set according to the
application, allowing setting of a small hysteresis for
severe, high-accuracy detection and a large hysteresis for
detection of large variation and prevention of chattering.

Timer functions

On-delay, off-delay and on-off delay timer functions are
provided, which allows for a wide range of detecting and
input conditions from the connected devices.
The delay time setting is variable between:
10 ms, 20 ms, 40 ms, 60 ms, 80 ms, 100 ms and 120 ms.

Teach hold function

The sensor has the ability to hold instantaneous data for an
object moving at a high rate of speed during full auto teaching.
This data is displayed when the teaching has been completed.

All amplifiers should show “0” with no work.

Failure such as light
intensity degradation
possible if a negative
value is shown.

Possible failure

Received light level indication going beyond the

If the received light level at light blocking
is 10 and the level at light reception is
6000, the light blocking / light reception
ratio is calculated as 600 times.

Level

The value for a deviation (positive or negative) of
received light level from the original level is shown at
