
Contrast sensor
It must be used as second synchronisation sensor, connected to the “sensor 2” connector.
Electrical connections:
BROWN wire (+24V)

Pin 9
BLEU wire (0V)

Pin 8
BLACK wire (signal)

Pin 7
WHITE wire

NC
Calibration:
After fitting the contrast sensor and implementing the electrical connections, place the sheet
(not in movement) so that the notches of start/end print is positioned in the sensor light spot and
press the Teach-in button; the sender light and the status indicator will blink slowly. After,
position the sheet so that the notches of start/end print is not positioned in the sensor light spot
and press the Teach-in button again; the sender light and the status indicator will blink slowly
again: this means that the calibration is completed correctly (if they blink fast means that the
contrast is insufficient).
Technical features:
• Scanning range: 12,5mm • Tolerance: ± 2mm
• Source and type of light: LED blue, green, red • Wave length: 470nm, 525nm, 640nm
• Light spot size: 1,5 x 6,5mm • Supply voltage: 24Vdc (± 20%)
• Power consumption: < 35mA • Switching output: NPN
• Connection type: connector M12, 4pin • Signal sequence: 10.000/s
• Response time: 50µs • Protection class: IP67
• Ambient operation temperature: -10 ÷ +55°C • Ambient storage temperature: -20 ÷ +75°C
Mechanical dimensions:
Fit it perpendicularly to the sheet so that it reads
the notches at start/end print. In the case of
objects with reflective or shiny surface, tilt sensor
by 10° to 15° relative to surface.
