Simple and compact design
Simple automatic sensitivity setting
Quick wire connection
Anyone can carry out the optimum sensitivity setting by
simply pressing two buttons.
A snap of the lever secures the connection of the sensor head
cables on the SU-7 amplifier. It is no longer required to strip
the wire insulation. Further, the exclusive stripper (accessory)
can be used to easily peel off the sensor cable outer sheath.
1 Aligning with the mark to be
detected, press the “ON” button.

Thickness: 10 mm 0.394 in
Installation space can be greatly reduced as the SU-7
amplifier is just 10 mm 0.394 in thick.

ENVIRONMENTAL RESISTANCE
Chemical resistant type
Caution: The outer fluorine sheath of the chemical resistant type sensor head,
SH-61R, cannot be cut off with the exclusive stripper.
FUNCTIONS
Nine advanced functions for versatile sensing
1
Since the sensor heads and the attached cables are
covered by fluorine resin, SH-61R can be used in a
harsh chemical environment.
Moreover, it has a long
sensing range of 2.5 m

Sensitivity for detection of minute differences can be set by
the push of one button without the presence of an object.

Suitable for detecting printed characters
Reliable glass substrate detection
It can be used to detect printed
characters because of its line
shaped projected area of 1 × 4
mm 0.039 × 0.157 in.
Its unique optical system enables
detection of transparent glass
plate, as well as, specular film
deposited glass plate at the same
distance.
Since it makes a judgment
based upon the total light
incident on the sensing area, it is
not easily affected by a deviation
in sensing object position.

4) Make sure to confirm detection with an actual sensor before use.
5) The optimum sensitivity stands for the sensitivity level when the
operation indicator just lights up in the light received condition.

ON under unstable sensing condition (restored automatically after 40 ms approx.), or if the sensing output is short-circuited
(restored when short-circuit is rectified).

Red LED (lights up when the sensing output is ON)
Green LED
“RUN” mode: Lights up under stable light received condition or stable dark condition
“SET” mode: At the time of sensitivity setting, blinks twice when the difference between ON and OFF levels is
greater than the hysteresis, but blinks 15 times when it is equal to or less than the hysteresis. Also
blinks twice after the interference prevention is set
“SET” mode → When “SIF” or “RUN” mode is selected: Blinks from 0 to 5 times according to the sensitivity margin

• Time chart
Power supply
If the incident light is stable in either the object present or object absent
state, by shifting the threshold level towards this state, stable sensing
is possible even if the incident light is unstable in the other state.
The setting level is the same as for limit sensitivity setting. However,
since the operating level is shifted after the normal sensitivity setting,
output operation is selectable.
Setting procedure
Instead of pressing buttons, the sensitivity can be set with the remote
sensitivity setting inputs. (There is no external sensitivity shift mode.)

Self-diagnosis function
• The external synchronization function can be used to
control the timing of sensing. Edge trigger or gate trigger
are available.
• The sensor checks the incident light intensity, and if it is
reduced due to dirt or dust, or beam misalignment, an
output is generated.

Test input (emission halt) function (SU-75 only)
• When the test input (emission halt input) (violet) is shortcircuited to 0 V (Low), the beam emission is halted. This
function is useful for a start-up test since the sensing output
can be made ON/OFF without the sensing object. Short-circuit
to 0 V and open the input, repeatedly. If the sensing output
follows this operation, the sensor is working well, else not.

The self-diagnosis output transistor stays in the “OFF”
state during stable sensing.
When the sensing output changes, if the incident light
intensity does not reach the stable light received level or
the stable dark level, the self-diagnosis output becomes
ON. It is automatically restored after 40 ms approx.
Further, the self-diagnosis output changes state when the
sensing output changes from Light to Dark state.
It is not affected by the output operation of the sensing
output.
In case of insufficient beam interruption, there will be a
time lag before the self-diagnosis output turns ON.
