Punch sensor
The punch sensor (1) recognises the
beginning or end of a label.
Varying forms of labels (e. g square or round),
different materials (e. g. card or self-adhesive
material), as well as different requirements
(e. g. transparency or reflex), require the use
of variably adjustable photoelectric switch.
A multitude of material properties (e. g. light
transparency) place extra demands on the
setting capabilities of the punch sensor.
•
Standard sensor: Transparency
•
Optional sensor: Reflex
The punch sensor can be moved at right
angles to the feed direction using an
adjustment knob which is accessed from
outside of the device.
