Tri-Tronics Mini Label Eye User manual

Indicator illuminates (green or red) on power up.
Power Up
Place the gap between labels in sensor’s view using
the Optical Path Alignment Guides (see Figure 1).
Tip: If the gap is difficult to work with, try removing
a label.
With the gap in view, press and hold AUTOSET.
Indicator turns amber, then back to red or green.
Indicator flashes red/green with insufficient signal.
Adjust threshold if necessary. Hold LT/DK to toggle Light On / Dark On.
The Optical Path Alignment Marks
are molded ridges highlighted here in red.

How to Specify
Mini Label Eye Sensor
The Mini Label Eye is a special purpose gap or slot sensor optimized to sense
adhesive labels adhering to a roll of backing paper. The MLE’s specially
designed optics greatly reduces sensitivity to web flutter. The high intensity IR
LED penetrates thicker backing material and reduces temperature drift. The
astonishing 35 microseconds allows the MLE to keep up with even the fastest
high speed rewinders. This miniature sensor can fit into many small spaces at
only 10mm wide. The fork design with intergrated bracket keeps mounting easy.
The oversize Status Indicator can be seen even from a distance away.
