  • Even though we have this part in stock, it may take several days for internal process to complete. Goods will be delivered within 5 -7 working days.

  • Manufacturer: Datalogic

  • SR21-IR

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

  • 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.

  • 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
