Light curtains for industrial and civil applications where it is necessary to detect, measure, and recognise objects.

Depending on the number and position of the beams engaged by an object, the measurement sensors can provide real time information to a PLC or PC in order to: 

• Detect the presence or absence of objects;
• perform a count;
• detect a position;
• detect a shape or a profile;
• measure dimensions. 

From the MICRON product range 4 models available in relations to the outputs. 

MicronConfigurator software for PC, with graphic user interface, is supplied with each light curtain (models A and B only). 

Models A and B are provided with an M5 4-pole connector for parameter configuration and monitoring of the light curtain. It's a USB interface to be connected to a PC using the CSU M5 cable.

Available Models:

MICRON A 

• Two analog outputs (0 ... 10 VDC) model AV or (4 ... 20 mA) model AC with programmable functions + Two programmable digital outputs 0 or 24V.MICRON A
• Solution providing simple measurement with easy interfacing.
• Ideal for object measurement and detection of dimensional limits.
• Can be provided in WT and WTH version but must be factory programmed. 

MICRON B 

• RS-485 serial line with programmable functions + two programmable digital outputs 0 or 24V.
• Solution providing complete and detailed information on the status of each beam via the RS 485 serial line and, by means of the two solid state outputs, further on/off information related to the occurrence of the programmed conditions.
• Ideal for dimensional measurement, detection of object profile and position.
• Can be provided in WT and WTH version but must be factory programmed. 

MICRON C 

• Two digital antivalent outputs 0 or 24V without the need for programming.
• Solution providing simple on/off information related to the status of the controlled area.
• Ideal for piece counting and detection of object presence/absence in the controlled field.
• Can be provided in WT and WTH version.
