REER Light Curtains

Reer Light Curtains

Safety Light curtains are electro sensitive devices using one or more light beams, emitted by an Emitter and received by a Receiver, to create an intangible controlled area.

Fundamental characteristics are:

Safety type - Defines the self-monitoring and safety principles contained in the device; it must be chosen as a function of the risk level characterising the machine.

Protected height - This is the height controlled by the light curtain. If it is positioned horizontally, this value shows the depth of the protected zone.

Range - This is the maximum working distance that may exist between the emitter and the receiver. When deflection mirrors are used, it is necessary to take into account the attenuation factor introduced by each of them, which it is about 15%.

Response time - This is the time it takes for the light curtain to transmit the alarm signal from the time the protected zone is interrupted.

Resolution - The resolution of a light curtain is the minimum size of an object that, placed into the controlled area, will obscure the controlled zone and hence stop the hazardous movement of the machine.

EOS4 Series

EOS Series

TYPE 4 integrated and compact Safety Light Curtain, Type 4 - SIL 3 and SILCL 3 - PL e. EOS4, with its small-size housing and minimum dead zone is ideal for the protection of any tool machine where space restrictions exist.


EOS2 Series

Type 2 - SIL 2 and SILCL 2 - PL d. EOS2, with its small-size housing and minimum dead zone is ideal for the protection of tool machines where space restrictions exist.


Micron Series

Micron Light curtrains

Light curtains for industrial and civil applications where it is necessary to detect, measure, and recognize objects. Depending on the number and position of the beams engaged by an object, Micron can provide real time measurment information to a PLC or PC.


REER Modular Controllers

Reer Controllers

Mosaic is a modular, configurable safety controller for protecting machines or plants.

Mosaic is capable of monitoring several safety sensors and commands, such as safety light curtains, laser scanners, photocells, mechanical switches, mats, emergency stops, two-hand controls, concentrating management of these in a single, flexible device.

The MSD software, installed on a PC, can be used to create complex logical conditions using logical operators and safety functions, such as muting, timer, counters, memories, etc. via an easy, intuitive graphic configuration interface. Configuration data are transferred to the M1 unit via a USB link.

Mosaic offers numerous advantages compared with safety solutions based on traditional components, such as relay type safety modules, as it:

  • Reduces the number of components and therefore footprint and wiring. Promotes faster electrical cabinet construction.
  • Affords the necessary logical configuration using a single, simple programming software, facilitating modifications by machine designers.
  • Makes it possible to set up tamper-proof safety systems.
  • Simplifies machine maintenance through the MCM memory card, which can be used to transfer the configuration program to a new Mosaic in just a few simple steps.



The safety Sin/Cos incremental SAFECODER encoder together with a Mosaic Safety Controller comprise a SIL 3 certified function for safe speed monitoring. They are characterized by a robust and reliable interface and the ability to handle high mechanical loads and electronic equipment.
