Simple automatic sensitivity setting
Quick wire connection
Anyone can achieve the optimum sensitivity by just 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.
1 Strip the cable sheaths
with the exclusive stripper.
2 Insert the wires into the
holes.
3 Flip up and lock the lever.

2 Aligning with the background, press the
‘OFF’ button.
Caution: The outer fluorine sheath of the chemical resistant type sensor head, SH-61R, cannot be cut off
with the dedicated stripper.
Nine advanced functions for versatile sensing
1 Limit sensitivity setting

one button without an object being
present.

2 Sensitivity shift
The set threshold level can be shifted from
the center towards either ON or OFF level.
3 Remote sensitivity selection SU-79
The amplifier stores four channels of
sensitivities. They can be selected by
the remote inputs.
SU-77
4 Remote sensitivity setting
The sensitivity can be adjusted from a
remote place.

(e.g.) Detecting polarity marks
on capacitors
• Suitable for detecting
printed characters
• It can be used to
detect printed characters because of its
line shaped projected
area of 1 4 mm
0.0390.157 in.
• Strong against
position deviation
• 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.
Glass substrate detection type / SH-72
• Reliable glass substrate detection
• Its unique optical system
enables detection of
transparent glass plate,
as well as, specular film
deposited glass plate at
the same distance.
• No dead zone
• Repeatability: 0.03 mm

Sensor head
This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.
• Use M4 screws to assemble the sensor head with the
optional sensor head mounting bracket MS-SH6-2, in
order to form the convergent sensing mode.
M4 screws [Material: Stainless steel (SUS304)]
(Please arrange separately.)
Always use the sensor head and the exclusive amplifier
together as a set.

Wiring
• Trim the cable ends
The stripper SU-CT1 helps
you to cut the cable and peel
the sheath off the cable.
To cut the cable or to strip the
sheath, insert the cable into an
appropriate hole as shown in
the right figure and press the
blade down.
Holes for cutting
the cable
Holes for stripping the sheath
Note: The outer fluorine resin sheath of SH-61R cannot be peeled off with
SU-CT1.
• If the attached sensor head cables need to be extended,
use two single core shielded cables of at least equivalent
quality.
If a joint terminal or connector is used for extension, refer
to the figures below. (The shielded extension cable must
be of "1.45 mm "0.057 in outer diameter.)

At the time of shipment, the
inner conductor is stripped
and cannot be used as it is.
Make sure to trim the cables.
Snap the cable lock

Caution
• After locking, if the lock is released and the cable is
removed, it can be locked again, as it is, only once. If
the locking is repeated three times or more, repeat the
process from Step 2. If the cables are locked and
released repeatedly, note that the cable ends may
break, resulting in a bad connection.
• If there is a shred of the cable left inside the cable inlet,
remove it before connecting the sensor head cables.
Turn the amplifier
upside down, and tap it

Setting procedure
The procedure is the same as for setting with sensitivity buttons, except that
instead of pressing the buttons, the remote sensitivity setting input wire is shortcircuited to 0 V. The mode selection switch is set to either the ‘SET’ or ‘RUN’ side.
• The stability indicator blinks twice if the difference between the ON
and OFF levels is sufficient for stable detection.
6
• The stability indicator blinks continuously if the difference between
the ON and OFF levels is so small that stable detection is not
possible.
Even though the sensitivity can be set and the sensor can work,
the sensing will be ambiguous.
(
Set the mode selection switch to ‘RUN’. Now the
sensitivity setting buttons (ON / OFF buttons) become
7 ineffective. Even if the buttons are touched by mistake,
the set sensitivity does not change.
)

If the incident light is stable in either the object present or object absent
