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.

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).
