Description
The 42JS VisiSight™ family of sensors offers a full range of sensing
modes in miniature rectangular housing. Visible light source is offered
in all models for ease of alignment. Additional transmitted beam
infrared status-indicator source models are offered for excellent
crosstalk immunity.
The 42JS VisiSight family provides an indication if the sensor operation
is unstable. An indicator flashes if the signal level is too close to the
detection threshold. This indicator helps in easy alignment of the sensor
and forewarns against detection of a background.
Features
• Visible light source that is offered on all models for ease of
alignment
• Optional snap-on adapter for 18 mm mounting
• Patented ASIC design offers linear sensitivity adjustment,
stability indication, and excellent noise immunity
• Compact sealed housing and cavity-free design to minimize
collection of dust and debris while allowing for easy sensor
cleanup
• Threaded metal M12 or M8 connector on pigtail
•360° visible status indicators
• Additional transmitted beam models available with Infrared
light source for excellent cross talk immunity
• Input to disable light source on transmitted beam emitter

Sensor Indicators
Indicator Status
6 Black wire or pin four of connector.
Background Suppression Sensors
Sensor Alignment
1. Verify that the sensitivity knob is set at its maximum (factory
default) setting.
2. Pan the sensor to the left, right, up, and down to center the beam on
the sensed object (for diffuse), reflector (for retroreflective), or
transmitter (for transmitted beam). Affix the sensor position when
the green status indicator is ON (not flashing) and the yellow
output indicator is ON (light sensed and L.O. output energized).
This configuration assures a good margin and that the signal
received is greater than twice the signal that is required to energize
the L.O. output.
3.
a. For diffuse applications, remove the object being sensed and
observe the green status indicator. If the green indicator is
flashing (at 6 Hz), the sensor is receiving more than half the
signal required to energize the L.O. output when there can be
minimal or no received signal. It indicates that the sensor is
getting close to detection of the background. Stability can be
optimized by reducing the reflectivity of the background or
reducing the sensitivity. Reduce the sensitivity to shorten the
sensing range. If sensitivity is reduced, check that both the green
and yellow indicators are on when the object is detected (step 2).
In applications where the full range is needed, for example,
sensitivity cannot be reduced, the green indicator can be left
flashing.
b. For retroreflective and transmitted beam applications, place the
object to be sensed in the beam path and observe the green
indicator. If the green indicator is flashing (at 6Hz), that sensor
is receiving more than half the signal required to energize the
L.O. output when there can be minimal or no signal received. It
indicates that the object being detected is letting some light go
through (semi-transparent or too small). Adjust sensitivity and
repeat step 2.
Crosstalk Avoidance
For applications of transmitted-beam sensors which require adjacent
pairs to be mounted close, use the red indicator and infrared indicator
pairs as adjacent pairs.
The following spacing (center to center) between the adjacent pairs can
be maintained to avoid crosstalk:
1. Red indicator pair that is adjacent to the infrared indicator pair:
a. 60 mm (2.4 in.) for sensing range up to 1.6 m (4.8 ft)
b. 20 mm (0.8 in.) for sensing range greater than 1.6 m (4.8 ft)
2. Two adjacent pairs of red indicator models or two adjacent pairs of
infrared indicators: 360 mm (14 in.).

Target
IMPORTANT Due to the detection method, targets traveling horizontally to
the sensor optics are detected. Targets traveling vertically
cannot be accurately detected. For excellent reliable
background suppression, a minimum separation distance of
6mm (0.24in.) is recommended between the target and the
background.

Rockwell Automation Publication 42JS-IN001B-EN-P - January 2017 3
VisiSight Photoelectric Sensors
Two pairs of red indicators or two pairs of infrared indicators can be
mounted adjoining each other by transposing the emitter and receiver
positions of the second pair vs. the first pair. There is no crosstalk as
each receiver only receives signal from one emitter.
Mounting the Sensor
Securely mount the sensor on a firm, stable surface, or support. An
application that is subject to excessive vibration or shifting can cause
intermittent operation. Adapters and mounting brackets are available
for a flexible installation that can may include vibration and shock while
shifting. See Accessories on page 3 for more details.
Wiring Diagrams
Cable connection is shown in the following diagrams. Pin numbers
correspond to an M12 or M8 male connector on the sensor.
PNP Models with Complementary Outputs
Transmitted Beam Emitter
7 For normal operation, black wire (pin 4) needs no connection. To disable light source, connect black wire
(pin 4) to +V.
Approximate Dimensions [mm (in.)]
Accessories
The sensor can be mounted using an 18 mm snap-on adapter 8
(60-AJS-18) as shown. Align the slotted hole with the slotted hole on
the sensor and snap on.
To remove the sensor from the adapter, undo the snap by using a flat
screwdriver.
8Damage can occur to snap-on adapter if torque above 1.69 N•m (15 in•lb) is applied to the 18 mm mounting
nut.
