Set up a safety system yourself

ReeR Safety Mosaic safety PLC is modular and programmable for securing machines and installations. The safety system is suitable for monitoring various safety sensors such as safety light curtains, laser scanners, photocells, mechanical limit switches, mats, emergency-off buttons and two-hand operation in one flexible system.

Switch components with Mosaic

When composing your safety system and when using ReeR Safety Mosaic, you are not 'stuck' to ReeR Safety. Other safety components can also be connected to ReeR mosaic. The system consists of a master module ReeR Safety Mosaic M1 and a maximum of 7 expansion modules that are connected via the bus at the rear. Read more about safety PLC Mosaic.

Safety PLC - Safety controller- ReeR Mosaic

Application example - ReeR Safety

Application example - Securing robot cell with light curtains - ReeR Safety

A robot cell and conveyor belt with in- and outgoing fork-lift trucks

A robot cell stacks a pallet from a conveyor belt. The pallets are then picked up and moved by a forklift truck. The forklift trucks enter the secured area and then leave the secured area. In addition to ReeR Safety light screens, emergency stop buttons, fence protection with ReeR Safety Magnus RFID switches are also used.

Mosaic M1S module with 4 OSSD outputs - ReeR Safety

The Mosaic M1 main module of the safety PLC - Mosaic has undergone a transformation. Both visually and technically, the new Mosaic M1S is an improvement over its predecessor. The labels have been replaced with laser engraved information on the outside of the modules. The gray modules have been given a new look: black!

New functions

New features include four OSSD safety outputs (Pld) or two pairs of OSSD outputs (Ple) and the ability to process 128 logical operators, making security applications more powerful. In addition to the Mosaic M1S module, an I/O extension module has been added to the range. The new MI8O4 provides 4 OSSD outputs. Read more about the safety controller from ReeR

Safe inductive sensors

The safe inductive sensors from ReeR Safety can be used for door detection, gearwheel detection for speed monitoring, shaft position detection, end stop robot cells and positioning machines. Machines and robots can be secured to a safety class of PLd or SIL2 with the use of these sensors.

Connect the safe inductive sensor to safety relay

The two safe OSSD outputs can be connected directly to the safety relay "AD SR1" or to the safety PLC "Mosaïc M1". The inductive fail safe sensors all have a degree of protection of IP65 and IP67. There is one version with a protection rating of IP69K that is suitable for use in the pharmaceutical and food industry. The inductive sensors are available in M12, M18, M30 or a block form 40 x 40 mm. Read more about safe inductive sensors.

R-SAFE series non-contact safety switches - ReeR Safety

R-SAFE series non-contact safety switches

The R-SAFE series of contactless safety switches uses RFID technology to communicate with authorized actuators. This system helps prevent machines and equipment from being activated if an authorized RFID actuator is not present.

Connecting 16 switches in series

An important feature of this new product is the ability to connect up to 16 RFID sensors in series, resulting in an efficient and cost-effective installation. Through the Mosaic safety PLC, it is possible to read the status of the individually connected RFID sensors in series.

Mosaic Safety Designer (MSD) software

This safety switch is fully mechanically compatible with other RFID safety sensors from ReeR Safety, including the Magnus RFID and Magnus MG "S" series. Additionally, the RFID switches can be seamlessly integrated with ReeR's modular Mosaic safety PLC. The Mosaic Safety Designer (MSD) software enables users to easily design, configure, and manage safety systems, significantly improving the flexibility and scalability of safety solutions. Read more about R-safe contactless safety switches.

Safety system - Safelock - ReeR Safety

The Safelock safety system from ReeR Safety is a safety switch that is used to protect personnel when opening doors and gates that give access to hazardous areas. The safety switch works by monitoring and interrupting the safety circuit during hazardous scenarios. The Safelock safety system locks and unlocks access to hazardous areas and guarantees safety until the danger has passed.

Available models

The SLK-M switch is activated by a spring and unlocking takes place by applying voltage / current. The SLK-E works in reverse. The safety switch is activated by voltage and released by activating a spring.

Safety photocells ILIONN - IL10 - IL20 - ReeR Safety

ReeR safety photocells can be installed or installed in very compact spaces, thanks to the compact size of the security system, while the possibility to use more photocells offers the maximum flexibility when positioning the protective beams.

Mosaic security controller

The photocells must be connected to the control unit, for example: standard AU SX or AU SXM control unit with muting or Mosaic for forming a security system that can consist of 1, 2, 3 or 4 photocells with a single beam. In case of connection with Mosaic safety controller, the number of photocells depends on the configuration of the security system.

Speed monitoring relay - ReeR Safety

When the number of revolutions of a machine becomes too high, a dangerous situation can arise and the safety of man and machine is jeopardized. To protect machines and persons against unsafe situations and to comply with the set standards, a speed monitoring relay is used.

Encoders and inductive sensors

The speed can be monitored using sensors such as encoders or inductive sensors. There are also speed monitoring relays that are connected directly to a motor without the intervention of sensors. Read more about speed monitoring with speed monitoring relays.
