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, namely PNP or NPN. If no load is connected,
the sensor defaults to PNP.
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.
Perform a selection as follows:
1. To access output type: Press and hold the push button for 12
seconds (until both LEDs start flashing synchronously). Upon
button release, 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 activation of
the button will cycle to the next output setting. The type
selected is indicated by the LEDs. The sensor retains the setting
configured by the last button activation 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 produces the same result as a button activation,
while no connection is equivalent to not pressing the button.
The sensor can be taught by following the same teach/timing
sequence as used in the push button teach. For example, connect
to the +V for more than three seconds to align and install the
reflector, disconnect from the +V; while the reflector is in the
sensor field of view and there is no target, connect to the +V for
less than one second to complete the teach process. All push
button functions can also be carried out via RT.
IO-Link
See instructions for IO-Link on
www.ab.com/literature
. 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 following diagrams show the quick-disconnect connector.
The pin numbers correspond to male connectors on the sensor.

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.
