The LABEL•EYE® is a special purpose gap or slot sensor optimized to sense adhesive labels adhering to a roll of backing paper. The web of labels is directed from a “roll” across a peeler plate or around a sharp edge. As the web passes around the sharp edge of the peeler plate, the adhesive label peels from the backing material. The function of the LABEL•EYE® is to look through the backing paper to detect the "gap" between the labels and signal the labeling machine to stop the dispensing mechanism before the label is completely dislodged from the backing material. With the next "up" label protruding off the end of the peeler plate, it is now perfectly positioned to be applied to the next product as it passes by on a conveyor.

PUSH BUTTON SETUP
Setup is acompleshed by the single push of a button. Elininates the need for screw drivers to adjust the sensor. Place the label gap in position and press the "Normal" button for opaque labels or press the "Translucent" for translucent labels.

STATUS INDICATORS
Displays status of output, shorted output, AUTOSET, and AUTOSET Status.

REMOTE AUTOSET
Remotely adjust the sensor from a push button momentary switch or a touch screen to PLC instantaneously.

Features

Features and Options:

100 microseconds Response Time
Two AUTOSET Modes: Normal or Translucent
Cable and quick disconnect models
NPN and PNP outputs
One button AUTOSET

Benefits:

Easy to Set Up
Accurate and repeatable
Easy to mount
Common style and configuration for compatibility

SUPPLY VOLTAGE:
10 to 30 VDC
Polarity Protected

CURRENT REQUIREMENTS:
45 milliamps (exclusive of load)

OUTPUT TRANSISTORS:
(1) NPN and (1) PNP sensor output transistors
Outputs sink or source up to 150 milliamps (current limit)
All outputs are continuously short circuit protected

RESPONSE TIME:
Light state response = 100 microseconds
Dark state response = 100 microseconds

LED LIGHT SOURCE:
High Intensity red LED
Pulse Modulated

AMBIENT TEMPERATURE:
-40ºC to 70ºC (-40ºF to 158ºF)

PUSH BUTTON CONTROL:
Automatic setup routines based on web opacity
One push button setup
Pushing both buttons simultaneously inverts output

HYSTERESIS
Minimal hysteresis promotes the dection between the backing material and the label depending on the settings

LIGHT IMMUNITY
Responds to sensor's pulsed modulated light source, resulting in high immunity to most ambient light

INDICATORS
Green LED flashes when AUTOSET routine is activated and stays illuminated when AUTOSET is completed
Red LED illuminates when sensor's output transistors are "ON". NOTE: The ststus of the output transistors can be inverted by pushing both buttons simlutaneously. If Output LED flashes, a short circuit condition exists.

RUGGED CONSTRUCTION:
Chemical resistant high thermoplastic PPS housing.
Waterproof, ratings: NEMA 4 and IP66
Conforms to heavy industry grade CE and UL requirements

Features and Options:

LIGHT SOURCE SELECTION

Red (Visible) Light Source
Visible red LED light source recommended for sensing transparent/translucent objects. Outperforms infrared light in many moderate to low contrast applications. Also recommended for use with plastic fiberoptic light guides.
