PHOTOSWITCHr Bulletin 45LPT Optical Label Sensor

45LPT-1LEB1-P4

IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.

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.
