1.3 Laser Description and Safety Information
CAUTION: Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure. Do not attempt to disassemble this sensor for
repair. A defective unit must be returned to the manufacturer.
1.3 Class 2 Laser Models
CAUTION: Never stare directly into the sensor lens. Laser light can damage your eyes. Avoid
placing any mirror-like object in the beam. Never use a mirror as a retroreflective target.
For Safe Laser Use - Class 2 Lasers
•Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.
Reference IEC 60825-1:2007, Section 8.2.
Class 2 Lasers
Class 2 lasers are lasers that emit visible radiation in the wavelength range from 400
nm to 700 nm, where eye protection is normally afforded by aversion responses,
including the blink reflex. This reaction may be expected to provide adequate
protection under reasonably foreseeable conditions of operation, including the use of
optical instruments for intrabeam viewing.
Figure 3. FDA (CDRH) warning label
(Class 2)
Class 2 Laser Safety Notes
Low-power lasers are, by definition, incapable of causing eye injury within the
duration of a blink (aversion response) of 0.25 seconds. They also must emit only
visible wavelengths (400 to 700 nm). Therefore, an ocular hazard may exist only if
individuals overcome their natural aversion to bright light and stare directly into the
laser beam.

1.3 Class 1 Laser Models
Class 1 lasers are lasers that are safe under reasonably foreseeable conditions of
operation, including the use of optical instruments for intrabeam viewing.

2 Sensor Installation
NOTE: Handle the sensor with care during installation and operation. Sensor windows soiled by
fingerprints, dust, water, oil, etc. may create stray light that may degrade the peak performance of the
sensor. Blow the window clear using filtered, compressed air, then clean as necessary using 70%
isopropyl alcohol and cotton swabs or water and a soft cloth.
2.1 Sensor Orientation
Correct sensor-to-object orientation is important to ensure proper sensing. See the following figures for examples of
correct and incorrect sensor-to-object orientation as certain placements may pose problems for sensing distances.

Figure 16. Window and Midpoint Example
The Midpoint TEACH uses both the window size and the
TEACH midpoint to determine the actual measurement
window. For example, a window of 200 mm with a midpoint
of 600 mm places the measurement window from 500 mm to
700 mm.
To use Midpoint TEACH:
1. Set the window size using Window Size on page 15.
2. Set the measurement window using TEACH Midpoint
on page 16.
The Midpoint TEACH options for D1_OUT and D2_OUT are
independent settings.
Window Size
The WndSize option sets the window size that the Midpoint TEACH uses to set the setpoint one and setpoint two
thresholds.
The Midpoint TEACH will fail if one of the setpoints is beyond the measurement range. The bigger the window size, the
smaller the acceptable TEACH range.

3.5.7 Mode
The Mode option sets the output to the desired mode.
Navigate: MENU > Dx_OUT > Mode
Remote Input: Available
Default: Wnd mode
The following table describes the sensor modes.
Mode Description
Alarm Alarm Mode: The Discrete Output is Off while a target is detected by the sensor at any distance.
When a loss of signal occurs, the Discrete Output is On.
This mode has no associated thresholds.
Health Health Mode: The Discrete Output is On while a target is detected by the sensor at any distance.
When a loss of signal occurs, the Discrete Output is Off.
This mode has no associated thresholds.
SPt Switch Mode: The Discrete Output is On while a target is detected nearer than the switch point threshold.
When a target is detected farther than the switch point threshold or the signal is lost, the Discrete Output is Off.
SPt Switch Mode: The Discrete Output is Off while a target is detected nearer than the switch point threshold.
When a target is detected farther than the switch point threshold or the signal is lost, the Discrete Output is On.
Wnd Window Mode: The Discrete Output is On while a target is detected between the SPt1 and SPt2 thresholds.
(Default)
When a target is detected outside the SPt1 and SPt2 thresholds or the signal is lost, the Discrete Output is Off.
Wnd Window Mode: The Discrete Output is Off while a target is detected between the SPt1 and SPt2 thresholds.
When a target is detected outside the SPt1 and SPt2 thresholds or the signal is lost, the Discrete Output is On.

3.5.8 Switch Point Reference (SPtRef)
The SPtRef menu only displays for a discrete output when it is set to switch mode. The SPtRef settings, object or
background, for the two discrete outputs are set independently. This setting cannot be changed with remote teach.
•Object (default). Object mode sets the switching threshold just past the location of the taught object, farther away
from the sensor's face.
•Background. Background mode sets the switching threshold in front of the taught object, closer to the sensor's
face.
The distance between the surface of the taught object and the switching threshold varies depending on measurement
strength and can be affected by target distance, color, reflectivity, etc. Use object mode when teaching an object if a
change in state is required when the object is no longer present. Use background mode when teaching background so that
the output state changes when a new object is in front of the background.
Navigate: MENU > Dx_OUT > SPtRef
Remote Input: Not available
Default: Background
