Installation Instructions
42JT VisiSight™ Photoelectric Clear Object Sensors with IO-Link
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Default Settings:
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.
