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.
