Rockwell Automation 42JT VisiSight Photoelectric Polarized Retroreflective Sensors - Manual

Installation Instructions—42JT VisiSight™ Photoelectric
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.
Sensor User Interface
LED Status
The table below provides LED status in the RUN mode, during
operation. The sensor is always in RUN mode, except when being
taught.
