Rockwell Automation 42JT VisiSight Installation Instructions

42JT VisiSight™ Photoelectric Diffuse Sensors

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: Light Operate (Output ON when target is
detected)
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:
