Polarized Retroreflective Sensors with IO-Link
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Default Settings:
The factory default settings are configured so that no teaching is
required for a vast majority of the applications.
Sensing Range: Maximum Setting
Output Mode: Dark Operate (Output ON when the light
between sensor and reflector is blocked)
Output Type: Auto PNP/NPN or IO-Link. In Auto PNP/NPN mode,
the sensor continuously monitors the load connection and
automatically configures the output to PNP or NPN.

Mounting the Sensor
Securely mount the sensor on a firm, stable surface or support. An
application which is subject to excessive vibration or shifting may
cause intermittent operation. For installation convenience,
Rockwell Automation offers a wide range of mounting brackets
(see the Accessories section for more details).
Alignment Indication
For short range applications the visible light beam of the sensor
suffices as alignment aid.
The alignment feature may be used for longer range applications.
Alignment of the sensor is indicated via change in intensity of the
green LED in the Alignment Mode, as follows:
1. Press and release the push button twice within three seconds.
After three seconds, the green LED turns OFF for 0.5 second
indicating the sensor is in the alignment mode.
2. Align the sensor to the reflector. The intensity of green LED
increases with better alignment. Secure it in a position that
yields the highest intensity of the green LED. Press and release
the button once to return to the RUN mode—or the sensor
returns to the RUN mode automatically in two minutes.
VisiSight™ Configuration
The 42JT VisiSight is configured using the push button Remote
Teach or via IO-Link and the LED indicators on the sensor. There
are five features that can be configured:
• Static Teach: Standard sensitivity/sensing range adjustment
• Dynamic Teach (running process)
• Light operate (L.O.) or dark operate (D.O.) output
• Auto PNP/NPN, dedicated NPN or dedicated PNP
• Push button lock/unlock
The sensor output is disabled during Teach.
Teach Sensitivity/Sensing Range
The default setting is the maximum sensitivity/range.
Static Teach
Teaching the sensitivity/sensing range is a two step process: teach
the reflector (first condition) and teach “target” (second
condition).
Standard Teach
1. To teach the reflector (first condition):
Align the sensor to the reflector. Press and hold button for three
seconds until the yellow LED starts flashing. Release the button.
The first condition has now been taught.
t > 3 s
Reflector
2. Teach “target” (second condition):
Restore to factory default setting of maximum range: Perform
steps 1 and 2 with “no target” in the sensor’s field of view and no
reflector.
Dynamic Teach (Running Process):
If the targets to be detected are moving with the sensor aimed at
the running process, press and hold the button for three seconds
until the yellow LED starts flashing. The sensitivity will
automatically be taught in the next 30 seconds provided the
sensor sees two cycles of “target” and “no target.”
Teach Light Operate (L.O.) or Dark Operate (D.O.)
The default setting of the output is dark operate (D.O.)
D.O. setting means that output turns ON when the target is
detected. If the application requires the output to turn OFF when
the target is detected, the setting may be changed to light
operate (L.O.).
1. To access the teach output mode setting:
2. To change the sensor output mode setting:
Output Type Selection:
Auto PNP/NPN, Dedicated NPN, Dedicated PNP)
The default setting is Auto PNP/NPN. This means the sensor
monitors the load connection and automatically configures for
the proper operation, i.e., PNP or NPN. If no load is connected, the
sensor defaults to PNP.
Insert the target between the sensor and the reflector. Press and
release the button. The teach process is complete.
If the push button is not pressed within 30 seconds, the sensor
exits teach mode and returns to RUN mode without learning
new setting.
Press and hold button for six seconds until green LED starts
flashing. Release the button. The current setting is indicated by
the yellow LED:
L.O.: Yellow LED ON
D.O.: Yellow LED OFF
Press and release the button within ten seconds to toggle from
L.O. to D.O., the selection indicated by the yellow LED.
The sensor retains the setting per the last button depression and
returns to the RUN mode ten seconds after the last button is
depressed.

The following applications are covered with dedicated PNP or
dedicated NPN selection:
a. Parallel wiring of multiple sensor outputs: select dedicated
PNP or dedicated NPN setting, as needed.
b. If the load is connected for NPN configuration but to a
different power supply than the power to the sensor or via a
load enabling contact (e.g., a relay contact in series with the
load): select dedicated NPN.
Selection can be made as follows:
1. To access output type: Press and hold the push button for 12
seconds (until both LEDs start flashing synchronously). At the
release of the button, the current setting of output type is
indicated by the slow flashing of the LED (or LEDs) as follows:
• Auto PNP/NPN: both LEDs flashing
• Dedicated NPN: green LED flashing
• Dedicated PNP: yellow LED flashing
2. To change output type: Press and release the push button
within ten seconds to select desired type. Each press of the
button will cycle to the next output setting. The type selected
is indicated by the LEDs. The sensor retains the setting per the
last button depression and returns to the RUN mode ten
seconds after the last button is pressed.
Push Button Lock/Unlock
The push button or remote teach (RT) can be used to prevent
unauthorized users from changing teach settings.
To lock the push button: press and release the button three
times within three seconds. Both LEDs flash synchronously for
three seconds indicating that the push button is now locked.
To unlock the push button: press and release the button three
times within three seconds. Both LEDs flash asynchronously for
three seconds indicating that the push button is now unlocked.
Permanent Lock: The push button may be permanently locked
by connecting the white wire (pin 2) to –V.
Remote Teach (RT)
The sensor can be taught remotely via the white wire (pin 2).
Connection to +V acts the same as the button being pressed and
no connection is the same as the button not being pressed. The
sensor can be taught by following the same teach/timing
sequence as used in the push button teach (e.g., connect to the
+V for more than three seconds to teach the “target,” disconnect
from the +V; remove the target and connect to the +V for less
than one second to teach the “no target” condition. All push
button functions can also be carried out via RT.
IO-Link
See instructions for IO-Link on www.ab.com. Remote Teach (pin 2)
is disabled in IO-Link operation. If output is selected as dedicated
NPN, IO-Link communication is unavailable.
Wiring Diagrams
The quick-disconnect connector is shown in the following
diagrams. The pin numbers correspond to male connectors on
the sensor.

Integral Pico (M8) Male QD
Output Wiring
Normal operation: no connection (disabled in IO-Link operation).
Remote teach: connect to +V. Refer to the Remote Teach section.
push button lock: connect to -V. Refer to the push button Lock/Unlock section.
