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.

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.

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). 2. Teach “target” (second condition): t < 0.5 s Insert the target between the sensor and the reflector. Press and release the button. The teach process is complete.

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. 2 1.
