Bulletin 45CPD Analog Laser Sensor
Description
The 45CPD sensor is a Class 1 infrared laser sensor that provides
long distance sensing with both analog and discrete outputs. It is
set up using the Teach-In buttons on the top of the sensor and
can be programmed for several modes depending on the
application: object detection (single or dual output), object
position (analog output), object detection (background
suppression), or object detection (reflector mode).
This sensor utilizes the time of flight principle and has a relatively
small beam spot for applications typical for this sensing range (up
to 6 m). The sensor is completely self contained in an IP67
enclosure and does not require any external control devices
which add cost and require additional mounting space.
For convenience purposes, the 45CPD utilizes a visible red Class 2
laser for alignment purposes during the set up of the sensor in an
application. The Class 2 laser is automatically shut down when the
sensor is placed in normal operation and the Class 1 “eye safe”
laser is used.
The 45CPD can be easily set up by mounting the sensor such that
the target is within the operating range of the sensor, and
teaching in the appropriate set points required for the
application. The sensor can be set with any combination of 1 or 2
discrete PNP outputs and 4…20 mA analog output. The discrete
outputs can be set for Light Operate (L.O.) or Dark Operate (D.O.)
and the analog output is automatically scaled between the
taught set points with either a positive or negative slope.
The 45CPD is an excellent solution for long range detection and
measurement applications including: distance measurement,
verifying material position, stack level, thickness measurement,
roll diameter, web winding/unwinding, positioning fixtures, error
proofing, inspection, long standoff distance (hot or limited space),
level monitoring, and box width measurement.

The 45CPD sensor is a Class 2 laser product. It utilizes a Class 2
visible red laser for alignment purposes during the set up. After
the sensor has been set up and is placed in the normal operation
mode, the Class 2 laser is shut down and a Class 1 Infrared laser
operates the device.
There is a natural eye aversion when looking into the laser beam
of a Class 2 laser. Do not look directly into the laser beam or
suppress the reflex to close your eyes.
The 45CPD should be mounted such that it is not directed at
people (head height) and the beam path is terminated at the end
of its functional path.
The laser safety label on the 45CPD sensor should be visible after
installation.

Wiring
The 45CPD photoelectric sensor is available with a micro quickdisconnect for ease of installation and maintenance. Rockwell
Automation recommends the use of the 889 Series of cordsets
and patchcords for quick disconnect model sensors. All external
wiring should conform to the National Electric Code and all
applicable local codes.
Wiring Diagram (45CPD-8LTB1-D5)*
Mounting
Securely mount the sensor on a firm, stable surface or support for
reliable operation. A mounting which is subjected to excessive
vibration or shifting may cause intermittent operation. The
45CPD-BKT1 mounting bracket is available for installation
convenience. Once securely mounted, the sensor can be wired
per the attached wiring diagram.

function press SET and the Speed LED will blink approximately
once per second. To select the higher speed function, press SET
and the Speed LED will blink approximately three times per
second. To teach the setting for either slow or fast speed, press
SET for approximately three seconds. The four teach-in indicators
will blink three times when complete. When the sensor is put in

General Set Up
The 45CPD is set up using the pushbuttons (SET and
) and the
LED indicators on the top of the sensor.
To begin the Teach-In process, Press the SET button for three
seconds.
This will automatically turn on the visible red alignment laser.
Scrolling through the Teach-In functions is done using the
button. After the last function is reached the menu is started
again from the first function.
To teach the selected function indicated by the teach-in LEDs as
shown in table above, press SET for approximately three seconds.
The LED will blink three times when complete.
After the desired functions are set, press SET and
simultaneously for approximately one second to exit the Teach-In
mode. The sensor will begin normal operation based on the
Teach-In settings. The visible red Class 2 laser will turn off and the
infrared Class 1 laser will turn on.
(Note: To reset the sensor to the factory setting, sensor should be
in the operating mode. Press the
button for approximately 15
operation, the LED will be turned on when running in the Slow
mode.)

detected the AS1 LED will blink.)
Press the button to advance to the AS2 function which is
indicated by the teach-in LED.
Position the target at the desired switch off point and then press
the SET button.
If desired, the output can be inverted for this switching window
(L.O./D.O. function). Press until both the AS1 and AS2 LEDs are
turned ON and then press the SET button. This is also indicated
by the “INV” text on the teach-in pad.

detected both AS1 and BS1 LEDs will blink.)
Press the button and advance until both the AS2 and BS2
function LEDs are turned on. This is also indicated by “100%”
analog on the teach-in pad.
Position the target at the desired 100% position (20 mA) and then
press the SET button.

To set the output for Q
procedure as in the single output
A in the reflector mode, follow the same
mode above. Set the AS1 and AS2
switch points such that the background “reflector” will be
approximately midway between them as shown in the figure
below. The background object can be a floor, wall, conveyor, etc.
The output can be set up for Light Operate or Dark Operate by
inverting the output. Press
until both the AS1 and AS2 LEDs are
turned ON and then press the SET button. This is also indicated
by “INV” on the teach-in pad.
After the settings have been completed successfully, press SET
and
simultaneously for approximately one second to begin
normal operation.
(Note: The minimum measuring range for the analog output is
600 mm. If the setpoints are less than 600 mm apart, the sensor
will automatically scale the analog output (0…100%) to 600 mm
and the midpoint of this will be automatically set at the midpoint
between the two original setpoints.)
(Note: To invert the slope, the 0% position and 100% position
settings will need to be reversed and reset. The 0% setting is the
“close” setting for a positive slope. For a negative slope the 0%
setting should be the “far” setting.)
Object Detection—Background Suppression
To set the output for Q
follow the same procedure as in the single output
except move the switch on point
A in a background suppression mode,
(AS1) closer to the sensor as
mode above,
Application Notes
1. The sensor should be powered for approximately five minutes
for maximum precision.
