The setting of the switching threshold is carried-out automatically by simply pressing a push-button, or dynamically during label (or other reference) movement. The SR21-IR model with infrared emission is ideal for label or hole detection on continuous surfaces, while the SR21-RG model with double red or green emission suits color print register mark detection on transparent films for automatic packaging.

Features & Benefits

  • Teach-in setting: easy and fast setting procedure
  • Dynamic setting: possibility to set the sensor while the labels film is moving
  • 12 bit resolution: high detection reliability for a precise reading
  • 25KHz switching frequency: high detection repeatability
  • Red/Green emission model: possibility to perform contrast application
