ReeR’s Metron automation, control and measurement light curtain can provide real time information to a PLC or PC. It is able to detect the presence or absence of objects, perform a count, detect a position, shape or profile, as well as measure dimensions.  All the operating functions are integrated into the receiver therefore Metron needs no external control unit.


Metron can be equipped with an RS-485 serial output and/or with 0 – 24 V pnp solid state outputs, through which the relevant data can be transmitted to the PC/PLC. Versions with RS-485 serial output are available and up to eight light curtains with different heights and beam spacings can be connected for multi-dimensional measurements.


Metron’s outputs and operating modes can be programmed via the Metronconf special software, supplied with each light curtain. It can be installed on any PC and it is provided with a user-friendly graphic interface.

In order to fulfil any application requirement, Metron is available in various models, having different beam spacings (resolution) of 5, 10, 25, 30, 50 and 75 mm, and with controlled heights varying from 140 mm to 2,525 m.

Metron conforms to CE – 89/336/EEC Electromagnetic Compatibility Directive and  23/73/EEC Low Voltage Directive. Special customised models are available upon request.
