DATALOGIC Label Sensor

DATALOGIC SR21 IR LABEL SENSOR – MICROPROCESSOR-BASED SLOT SENSORS FOR LABELLING AND PACKAGING.

Optical sensors work by placing a light source (usually infrared) under the web and a detector above the web that measures the brightness of light coming through. Changes in the opacity of the label compared to the liner between labels is used to detect the label edge.

The obvious problem with optical sensors is that they cannot detect transparent or clear labels, regardless of what the liner material is. Clear labels do not block any light, so the edge is not detectable by optical sensors.

Sometimes “eyemarks” are added to the liner – black bars between the labels. The cost of eyemarks is much greater than the cost of a sensor capable of sensing clear labels.

Optical sensors are perfectly accurate at low speeds. At higher speeds, their accuracy degrades a small amount.

The DATALOGIC SR21 IR LABEL SENSOR FEATURES:

The slot sensors of the SR21 series, with 2 mm slot width, are characterised by a high 12 bit (4096 steps) resolution. Also a low 20 µs response time and a switching frequency reaching 25 kHz.

The setting of the switching threshold is carried-out automatically by simply pressing a push-button.  Also you may change dynamically during label (or other reference) movement.

The SR21-IR model with infrared emission is ideal for label or hole detection on continuous surfaces. And the SR21-RG model with double red or green emission suits colour print register mark detection on transparent films for automatic packaging.

FEATURES:

  • Teach-in setting: easy and fast setting procedure
  • Dynamic setting: possibility to set the sensor while the label is moving
  • 25KHz switching frequency
  • Red/Green emission model: possibility to perform contrast application

APPLICATIONS:

  • Packaging lines
  • Labelling machines
  • Paper and Printing machines
