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. 
 

INDICATORS ARROWS (orange) 

The arrows show  the direction of knob rotation to adjust threshold. 
 

LIGHT/DARK SWITCH 

Switch to select LIGHT/DARK operation mode. 

 
SENSITIVITY ADJUSTMENT KNOB 

The knob rotation change the sensors sensitivity. 
Clockwise rotation

 Increse sensitivity. 

Counterclockwise rotation 

 decrese sensitivity. 

 

See the “SETTING” paragraph for setup procedure indications. 

 

INSTALLATION 

The sensor can be positioned by means the two Ø3.5 mm 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 

SENSITIVITY ADJUSTMENT 

 

-

 Select the function mode through 

light-dark switch. 

-

 

The setting procedure is faster 
rotating the sensitivity knob quickly 
(application with high contrasts), 
otherwise rotate the knob slowly to 
detect difficult contrast. 

-

 Position mark in front of the sensor 

light spot and rotate the sensitivity 
adjustment knob until the OUT LED is 
ON. The orange arrows indicate the 
direction of rotation. When the sensor 
reach the maximum/minimum 
sensitivity the indicator arrows blinks. 

  During adjustment phase the READY LED (green) turns OFF.  

 

LIGHT mode 

 

Rotate the sensitivity adjustment knob 

in clockwise direction until OUT LED 

turns ON. 

DARK mode 

 

Rotate the sensitivity adjustment knob 

in counterclockwise direction until OUT 

LED turns ON.

 

Position the background in front of the sensor light spot and rotate the 
sensitivity adjustment knob until the OUT  LED is ON. 

 

 

 

LIGHT mode 

 

Rotate the sensitivity adjustment knob 

in clockwise direction until OUT LED 

turns ON. 

DARK mode 

 

Rotate the sensitivity adjustment knob 

in counterclockwise direction until OUT 

LED turns ON.

 

Rotate the knob in opposite direction for ½ the number of turns required to 
detect the background. Position mark in front of the sensor light spot to verify 
the correct commutation of the output. 

At the end of the setting fase the READY LED (green) turns ON: the sensors 
had set the new sensitivity. 

 

LIGHT mode 

 

Rotate the sensitivity adjustment knob 

in counterclockwise direction. 

DARK mode 

 

Rotate the sensitivity adjustment knob 

in clockwise direction..

 

 

ACCESSORY FUNCTIONS 

ANALOGUE output 

The analogue output supplies a voltage proportional to the signal received by 
the sensor. The voltage supplied is 0 ÷ 5V.  
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. 

 
 
 

 
OUTPUT OVERLOAD 

The digital output overload is signalled by the rapid blinking of the READY 
LED. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

The sensors are NOT safety devices, and so MUST NOT be used in the safety control of 

the machines where installed.
