Installation Instructions
PHOTOSWITCHr Bulletin 45LFM Label Sensor
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Description
The Rockwell Automation 45LFM–CMBA1–D5 Label Sensor
is an innovative electronic sensor used to sense and/or count
labels. A signal is generated as the edge of the label passes
through the sensor. It can be configured to sense the leading
or trailing edge.
Features
S Consistently senses the presence of most labels on a web
S Clear labels on clear backing
S Clear labels on opaque backing
S Opaque labels on clear backing
S Opaque labels on opaque backing
S Count 50,000 labels per minute with registration error less
than 0.01 inch
S Heavy-duty metal housing
S Ideal for label counting and label registering applications

Mounting the Sensor
Mount the sensor perpendicular to the web so the web
passes through the sensor gap. The back of the web should
contact the mounting plate. Labels must pass under sensing
area marked [––SENSOR––]. Small labels (38.1mm (1.5in))
must be centered under the sensing area.
Electrical Connections
ATTENTION: Unused wires must be
insulated from contact with other
objects. All power must be off when
!
installing the sensor. DC ground is
connected to sensor body.
No power during
connection.
Labels must pass under Sensor.
Sensing Area
Sensor case is
grounded

Power
Sensor can be powered with 11–30V DC but optimum
performance is obtained with 24V DC. The negative side of
the power supply is grounded to the sensor body.
+Vin 24V DC
(11-30V DC)
50mA
Outputs
The NPN and PNP outputs are open-collector outputs. The
NPN output can sink up to 150mA and the PNP output can
source up to 150mA. Outputs are short circuit protected by
self-resetting internal fuses. These fuses will activate if the
outputs are connected directly to ground or power. Repeated
shorting will eventually cause the sensor to fail.
NPN Output
150mA maximum
PNP Output
150mA maximum
PNP Power In
+Vin maximum
(+30V DC)
The PNP POWER IN voltage must be connected to a supply
voltage and must not exceed +Vin
(+30V DC).
Output Polarity
Output polarity determines whether the output signal will go low or high on the label edge.
Note: Output polarity also depends on the direction of label movement through the sensor (see figure on page 4).
