SR21 Slot Photoelectric Sensors - DATALOGIC

INFORMAÇÃO
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.
CARACTERÍSTICAS E BENEFÍCIOS
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
