SR21 SERIES
The slot sensors of the SR21 series,
with 2 mm slot width, are characterised
by a high 12 bit (4096 steps) resolution,
a low 20 ms 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.
