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.
