Allen-Bradley Optical Label Sensor Installation Instructions
Allen-Bradley Optical Label Sensor is designed for high-speed web applications in packaging. This sensor detects standard or opaque labels using transmitted beam technology, providing a fast response time for label counting, web detection, double sheet detection, and mark detection on translucent film. The 45LPT offers versatile features like “One Touch” teachable capabilities, NPN/PNP output, and industrial anodized aluminum housing.

Description
The 45LPT is an optical label sensor designed exclusively for
the detection of standard or opaque labels on a high speed
web. The 45LPT provides a solution for the packaging
industry. Applications include label counting, web detection,
“double sheet” detection, and mark detection on a translucent
film.
Using transmitted beam technology the 45LPT senses the
leading edge of a label sending a discrete NPN or PNP output
within 50 microseconds which is compatible with most control
circuits found in factory automation systems. Other features
include “One Touch” teachable capabilities using either the
teach button on the sensor or remotely with a pushbutton
switch. For easy installation and versatility this sensor is
equipped with a 4-pin pico connector.
The 45LPT label sensor maintains all ratings that are
necessary for all applicable industries today: IP65, CE, cULus.

Initial setup includes mounting the sensor securely and then
providing power through a 4-pin pico cordset. The initial
factory settings have the threshold on the sensor preset so
that most opaque labels may be sensed on a translucent web.
2( 3 4 05"
To teach the sensor insert the material to be sensed into the
fork so that it enters the beam path.
Position the material so that the translucent web is in the
beam path in the fork.
Press and release the teach button once. The red LED on the
user interface will begin to blink.
While the red LED is blinking quickly insert and remove the
opaque label into and out of the sensors beam path until the
red LED stops blinking.
Test your setup by ensuring the green LED on the user
interface blinks when the label is inserted and removed.
To lock out user interface hold down teach button for six
seconds until red LED blinks once.
Release button and notice that both red and green LEDs are
illuminated on the user interface.
To unlock user interface hold down teach button for six
seconds until red LED turns off.
Release button and notice that only green LED is illuminated.
For remote teach follow the instructions in the wiring section
using a momentary pushbutton switch.
