Description

The 42EF RightSight™ family of photoelectric sensors offers high-performance
general-purpose sensing in a compact, flexible package. They are designed for
applications where simplified installation and maintenance are required.
RightSight sensors provide a range of mounting options. The sensors can be
through-hole mounted against a surface or can be installed using the threaded
18 mm base or nose mounting options.

Designed to withstand the rigors of food processing and material handling
environments, the 42EF RightSight standard models can withstand repeated 1200
psi and IP69K high-pressure washdowns.

Features

• Compact right angle housing with universal 18 mm threaded nose and base
mounting options

• Fixed, teachable, and adjustable sensitivity models

• 360° highly visible (status indicators helps operators verify proper
operation regardless of sensor installation location)

• Visible status indicator light-source for ease of alignment

• Alignment aid helps achieve excellent reliability operating margin

• Dual (NPN and PNP), NPN or PNP only models

• Linear sensitivity adjustment

• IP67 with 1200 psi; IP69K rated enclosure

• IO-Link 1.1 Communication protocol that is offered in all standard modes

Sensor User Interface

The green status indicator can also serve as a set-up alignment aid that indicates
that a margin of 1.5 has been reached. The sensor is receiving at least 1.5 times the
signal strength back from the target that is required to trigger an output signal. In
general, it is desirable to have a higher margin to help overcome any deteriorating
environmental conditions, that is, dust build-up on the sensor lens. When aligning
the sensor, the optimum performance can be obtained if this margin indicator is
illuminated with the target in place. When aligning diffuse mode sensors, be sure
that the sensitivity is set at its maximum setting; use the single-turn adjustment
knob on the front panel. Pan the sensor left, right, up, and down to center the beam
on the target. Decrease this setting to help prevent the sensor from detecting a
background object. If this problem persists, the application requires the use of a
background suppression, sharp cutoff diffuse, or retroreflective sensing mode.

The IO-Link output pin 4 (black) does not support the connection of multiple
sensors in series (for example, one sensor powering the next sensor). The
connection of multiple sensors in series can be achieved when using pin 2 (white)
outputs or by ordering a non-IO-Link catalog number. See the
Rockwell Automation® Knowledgebase or contact your local distributor for specific
ordering information. For additional information about sensor operation in IO-Link
mode, see publication 42EF-UM001
