DescriptionThe 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 AvoidanceFor 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.

2 Rockwell Automation Publication 42JS-IN001B-EN-P - January 2017


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 SensorSecurely 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 DiagramsCable 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.)]

AccessoriesThe 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.

8 Damage can occur to snap-on adapter if torque above 1.69 N•m (15 in•lb) is applied to the 18 mm mounting nut.
