INFO
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.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
APPLICATIONS
This product series has been developed to satisfy to requirements of the following reference applications:
- Packaging lines
- Labeling machines
- Paper and Printing machines
