DATASENSING
The SR21 series is a photoelectric slot sensor with 2mm slot width, are characterised by a high 12 bit (4096 steps) resolution, a low 20µs 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, 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 colour 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 label is moving
• 25KHz switching frequency
• Red/Green emission model: possibility to perform contrast application
APPLICATIONS
• Packaging lines
• Labelling machines
• Paper and Printing machines
