Description
The 42JS VisiSight™ family of photoelectric sensors features a full range of sensing modes in a miniature rectangular enclosure. The small housing combined with minimal adjustments; makes the 42JS VisiSight ideal for material handling applications where simplified installation and maintenance are required. A strong and visible light source is offered in all models for ease of alignment and a fast installation. The sensors can be mounted using the industry standard 25.4 mm hole spacing or using 18 mm hole mount when using the 60-AJS-18 snap-on adaptor.
The 42JT VisiSight models add flexibility by offering a tactile pushbutton that simplifies sensitivity and parameter setup. This makes the 42JT VisiSight a great solution for packaging and assembly applications that require some configuration in order to operate at optimal conditions. The 42JT offers unique "Auto PNP/NPN" output that continuously monitors how the load is connected and automatically configures the output for proper operation and output LED to indicate correct output status.

LED Color | State | Status |
| Green | OFF | Power is Off | |
| ON | Power is On | ||
| Flashing (6 Hz) | Unstable (0.5 < Margin < 2) | ||
| Flashing (1.5 hz) | Output short-circuit protection active | ||
| Yellow | OFF | Output de-energized‡ | |

42JT User Interface
The table below provides LED status in the RUN mode, i.e., during operation the sensor is always in RUN mode, except when being taught.
|
LED Color | State | Status |
| Green | OFF | Power is Off | |
| ON | Power is On | ||
| Flashing (6 Hz) | Unstable (0.5 < Margin < 2) | ||
| Flashing (1.5 hz) | Output short-circuit protection active | ||
| Yellow§ | OFF | Output de-energized | |
| ON | Output energized | ||
| § Except for color mark sensors: color mark sensors have PNP or NPN (push-pull) output. The above table shows LED status when output is connected as PNP. If connected as NPN, the yellow LED is ON when the output is de-energized and OFF when it is energized. | |||
Wiring Diagrams
Cable connections are shown in the following diagrams. Pin numbers correspond to an M12 or M8 male connector on the sensor.

42JT Push Button Lock/Unlock
The push button or remote teach (RT) can be used to prevent unauthorized users from changing teach settings.
To lock the push button: press and release the button three times within three seconds. Both LEDs flash synchronously for three seconds indicating that the push button is now locked.
To unlock the push button: press and release the button three times within three seconds. Both LEDs flash asynchronously for three seconds indicating that the push button is now unlocked.
Permanent lock: The push button may be permanently locked by connecting the white wire (pin 2) to –V.
42JT Remote Teach (RT)
The sensor can be taught remotely via the white wire (pin 2). Connection to +V acts the same as the button being pressed and no connection is the same as the button not being pressed. The sensor can be taught by following the same teach/timing sequence as used in the push button teach (e.g., connect to the +V for more than three seconds to teach the “target,” disconnect from the +V; remove the target and connect to the +V for less than one second to teach the “no target” condition. All push button functions can also be carried out via RT.

The 42JT mounting holes are located toward the rear end of the sensor while the 42JS mounting holes are located towards the front. Both sensors are compatible with the industry standard 25.4 mm mounting. The 42JT flexible mounting hole spacing ranges of 22.9…25.4 mm (0.9…1 in.), makes it compatible with the 24.1 mm (0.95 in.) hole spacing sensors.
