Precautions on Installation
●
Connecting the Sensor Head to the Amplifier Unit
Note
• The sensor is not guaranteed under the conditions of the warranty if the sensor head
is not connected correctly using the procedure described above.
• The sensor is not guaranteed under the conditions of the warranty if dust or dir t
attaches to the packing for the sensor.
• If the sensor head cannot be inser ted easily, fully remove any dirt or dust from the
amplifier unit and apply silicon grease to the opening.
1 Grasp the cap for the sensor head connector and insert the connector straight
in the direction shown in the diagram.

2
Insert the two upper tabs on the mounting fixture into the head installation hole
on the amplifier unit and pull the mounting fixture up in the direction shown in
the diagram. If the tabs do not slide into place easily, push on the bottom of the
mounting fixture.

Installation is complete when the head release lever locks into place as shown
in the following diagram.

Using Multiple Amplifier Units
(Interference Protection Function)
Installing multiple amplifier units (up to four) side by side on a DIN rail can protect
against interference.
Two end units (option item: OP-26751 (two units included)) are also required.
1
Install the sensor heads to the connected amplifier units.
Sandwich the amplifier units between the end units. Tighten the screws at the top
2
(two screws in two locations each) with a Phillips screwdriver to fix the end units.

Note
Check that the lower tab on the mounting fixture for the connector fits into the
groove on the bottom of the amplifier unit. If the tab does not fit into the groove,
remove the sensor head and try connecting it again.
Tab is fitted in the groove.

Mounting the Amplifier Unit
Mounting on a DIN rail
■
1
Hook the tab located on the bottom of the amplifier unit to the DIN rail as
shown in the figure. While pushing the amplifier unit in the direction of arrow
, tilt it in the direction of arrow 2 .
End units
Note
End units must be used.
Removing the Sensor Head from the
Amplifier Unit
1
Note
Do not pull on the cable.
1
Grasp the amplifier unit. While pulling the head release lever in the direction of
arrow 1 , slide the mounting fixture for the connector in the direction of arrow
. Pull the connector from the amplifier unit in the direction of arrow 3 .

pushing the amplifier unit in the direction of arrow 1 .
■
Mounting the amplifier unit sideways (Only for use with a single unit)
Mount the amplifier unit using M3 screws in the two locations as shown in the
diagram. Use a maximum torque of 0.6 N•m to tighten the screws.

Precautions for Installing the Sensor Head
Install the sensor head so that it can move at least 4 ° in any direction. This allows
beam-axis adjustment for the sensor head.
Use a mounting fixture especially made for beam-axis adjustment with an
elongated hole. Contact KEYENCE for more information about this item, which is
sold separately.
The sensor head cable in gray jacket is for the transmitter side and black jacket
for the receiver side.

In this mode, the setting value used will be the mean value of two light
intensity values obtained through detection with and without a workpiece.

Detecting Moving Workpieces
(Full Auto Calibration)
In this mode, the set value will be set to the mean value of the maximum and
minimum values obtained within a certain period.
1
Press the button for at least three seconds while the target workpiece is
passing the sensing area of the sensor head.
While the button is pressed, the sensitivity of the sensor will be set
•
according to the incident values.
●
Positioning a Target (Positioning Calibration)
1
Press the button without any workpiece placed in front of the sensor
head.
Place a workpiece on the position where you want to perform positioning.
2
Press the button for at least three seconds. When the indication flashes,
release the button.

Improving Performance against Dust and
Stains (Maximum Sensitivity Setting)
Set the sensitivity without a workpiece for a reflective type, and with a workpiece
for a thrubeam type. Set the sensitivity slightly higher than the amount of received
light at the setting time.

Setting Sensitivity with Signals from
External Devices (Page 6, No. 6)
By selecting "External calibration" in page 6, No. 6, the signal from an external
device can be used to set the sensitivity.
See "Using External Input" (page 4).
●
Percent (%) Calibration (Page 6, No. 3)
The sensitivity can be set as a percent (%) of received light intensity.
For example, when the percentage calibration target value is set to "-10P", pressing
SET
the button sets the value to 10% below the amount of received light.
When selecting the sensitivity setting method (page 6, No. 3), select percent
1
calibration, set the target value of calibration, and return to the normal display.
2
Press the button at the percentage for the desired reference for light
intensity.
SET
While percent calibration is selected, other calibrations (sensitivity setting) cannot
be used.
* External input (page 4) can still be used (PX-10/10P only).
