Contrast sensor
INSTRUCTION MANUAL
CONTROLS
OUT LED (yellow)
The red LED indicates the output status.
READY LED (green)
During functioning, the green LED permanently ON
indicates a normal operating condition; fast blinking
indicates an output overload condition.
MARK PUSH-BUTTON
The mark detection procedure is activated by pressing MARK push-button.
BKGD PUSH-BUTTON
The background detection procedure is activated by pressing BKGD push-
button.
See the “SETTING” paragraph for setup procedure indications.
INSTALLATION
The sensor can be positioned by means the two Ø3.5mm housing’s holes
using or threaded M5 holes with 6mm max. depth.
Warning: the use of excessively long screws can damage the product.
The connector can be oriented at five different positions, rotating the block.
The position chosen is guaranteed by a mechanical blocking system.
The rotation can be carried-out even after sensor installation as the connector
block is completely self-contained inside the housing.
The operating distance is measured starting from the lens front face.
The reading direction can be changed inverting the cap and lens.
Mark detection on a reflective surface is improved adjusting the beam
direction to 5° … 20° from surface axis.

CONNECTIONS
SETTING
DETECTION (MARK-BACKGROUND)
- Position mark in front of the sensor light spot and press MARK push-button
until the READY LED (green) turns OFF.
The sensor detects the mark alternating the red, green and blue emissions.
Avoid mark movements during this phase.
- Position the background in front of the sensor light spot and press BKGD
push-button. The sensor detects the mark alternating the red, green and
blue emissions. Avoid background movements during this phase.
The DARK/LIGHT operating mode is automatically selected by the sensor.
Dark mark - light background = dark mode; light mark - dark background =
light mode.
If the READY LED is permanently ON, the detection is successful.
If the LED blinks slowly, the detection has failed due to insufficient contrast.
The sensor returns to the previous setting by pressing MARK or BKGD push-
button.
Repeat the procedure from the beginning.
PNP/NPN OUTPUT SETTING
The digital output can be PNP or NPN configured.
- To change output press MARK and BKGD contemporaneously for 2 sec.
- The setting is signalled by the status change of the READY LED.
If the READY LED turns off after a 1 sec. pressure, release push-buttons
only after the re-powering of the LED (2sec).
- The output setting is signalled by the READY LED. Releasing the push-
buttons, the READY LED blinks once if the PNP output is set, blinks twice if
the NPN output is set.

OUTPUT OVERLOAD
The digital output overload is signalled by the rapid blinking of the READY
LED.
ACCESSORY FUNCTIONS
ANALOGUE output
The analogue output supplies a voltage proportional to the signal received by
the sensor. The voltage supplied is 0 ÷ 5 V.
The maximum voltage is obtained with reflective objects; on 90% white the
voltage is equal to 2.2 V.
DELAY SETTING
The DELAY extends to 20ms the minimum duration of the active output
allowing the slower interfacing systems to detect shorter pulses.
Delay activation
- Connect Delay signal (grey wire) to power supply.
Delay deactivation
- Connect Delay signal (grey wire) to 0V or leave unconnected.
The sensors are NOT safety devices, and so MUST NOT be used in the safety control of
the machines where installed.
