RFID SAFETY SENSOR
GENERAL DESCRIPTION
The R-Safe RFID safety sensor consists of a passive actuator (TAG) and a active RFID reader (SENSOR):
The RFID reader (properly mounted in front of the actuator) identification is possible via an RF signal.
The RFID reader enquires the actuator and waits for a code to be transmitted from the actuator.
The presence of a correct response allows the sensor to decide to set the logic level of the OSSD to high (LL1).
This product features the following electrical characteristics: Power supply: 24VDC Start/restart interlock (RESTART/AUTOMATIC) External relay monitoring (EDM) Two OSSD outputs, 300mA @ 24VDC Status output, 100mA @ 24VDC. Status output functionality for PLC Two safety inputs for serial connection Standalone Risk time: 70 ms
Three types of sensors are available (EN ISO 14119:2013 standard): 1) GENERIC -> The safety sensor accepts any ReeR RFID generic actuator (low coding level). 2) TEACH-IN -> The safety sensor accepts only one ReeR Teach-In R-SAFE RFID actuator (T) individually paired with the the sensor during the Teach-In process (high coding level). 3) UNIQUE -> The safety sensor accepts only one Unique R-SAFE RFID actuator (U) previously configured by ReeR (at factory). Sensor and actuator cannot be unpaired or individually substituted (high coding level).
MECHANIC
The R-Safe RFID sensor and actuator transponder are equipped with a hermetically sealed plastic housing. The sensor is equipped with cable, connector or directly with pig-tail cable with connector for external connections. The sensor complies with IP67 (IP69K for special models).

RFID SAFETY SENSOR
OPERATION
The RFID safety sensor is made up of a passive actuator (TAG) and an active RFID reader. The RFID reader must be mounted on a safety gate (or door, or mobile protection) in the front of the actuator to enable identification by means of an RF signal.
It is recommended to mount the sensor on the fixed part of the safety gate in order to
make wiring easier.
ACTIVATION CONDITIONS (Standard EN ISO 14119)
1) Gate closed, actuator in safe area
In this operating condition the reader/actuator distance is defined as < Sao: switching distance below which is defined the ON state; the OSSD safety outputs are active; led -> green.
2) Gate open, actuator leaving safe area
In this operating condition the reader/actuator distance is defined as >Sao: switching distance at which the ON state is about to end; the OSSD safety outputs are still active but once the limit zone Sar is reached, they will be switched OFF; led -> green or red
3) Gate fully open, actuator in hazardous area
In this operating condition the reader/actuator distance is defined as >Sar: switching distance at which the OSSD safety outputs are switched OFF and RFID signals the hazardous situation; led -> red

SERIAL MODE (R-Safe RFID Plus models)
In serial mode a maximum to 16 R-Safe RFID Plus sensors can be connected in series.
For a quicker and safe connection, ReeR recommends using its splitter connectors as
showed in Figure 6 and Figure 9.
In serial connection, the device can only operate in Automatic operation mode. If one or more sensor is deactivated (actuation distance = Sar) all downstream sensors
outputs will be deactivated with the programmable controller opening its OSSD outputs.
The next two sections extend the information on the use of the “STATUS” signal in serial mode. Serial connection: with an increase of the length and of the current drawn (load +
sensors), there corresponds a voltage drop in the system. Should this voltage be less than 20 VDC, an additional power supply must be provided.
The following schematic shows an example of series connection of 4 sensors (using the ReeR splitter connectors) with a Programmable Logic Controller.

8541613 – 12/01/2023 – Rev.0
RFID SAFETY SENSOR
In order to guarantee the highest level of safety (PL e), it is necessary to include a safety
device (PLe), such as a safety module or programmable controller (e.g., ReeR MOSAIC M1S) at the end of the chain to evaluate the condition of the static OSSD outputs.

STATUS output transmission protocol
A system STATUS output is available in the RFID sensor for diagnostics. The output signal is a 24 VDC square waveform (Figure 10) that corresponds to the status of the sensor chain.
Figure 10 – STATUS serial asynchronous transmission
The timing requirements for data transmission are not critical to the safety of the device,
as “STATUS” is not a safety signal. The following table shows the timing requirements.

SERIAL STATUS MODE
The serial output waveform containing the sensor’s STATUS is shown in “Figure 13” for three sensors connected in serial modality. The first and second sensors are in CLEAR status with the actuator inside the Sao distance. The third sensor has its transponder at the Sar distance; therefore, it is in BREAK status.

INSTALLATION
RFID SAFETY SENSOR
MECHANICAL INSTALLATION
Precautions
Before installing the product, it is important to perform a specific risk analysis in
accordance with the requirements of the Machinery Directive (2006/42/EC).
ReeR guarantees the functional safety of R-Safe RFID, but is not responsible for the
performance of the system in which it is installed.
Respect the correct activation direction described below. Remove power supply from the product before proceeding with mechanical installation. It is not permitted to fix sensor and actuator with less than two screws (EN ISO 14119). Follow the installation rules described in the standard EN ISO 14119. The use of anti-unscrewing screws is mandatory (EN ISO 14119). Fasten the devices to the gate using M4 x 20 screws or alternatively 3.5 x 19 cylinder
head self-threading screws with a tightening torque of 0.8 … 1.5Nm.
Assembly
Place the sensor and actuator as shown in the following figures. Follow the instructions below in particular:
Mount the sensor to the fixed part of the safety gate/door and the actuator to the
moving part.
For actuation direction 1, place the sensor and actuator facing each other with the
centering marks at a distance d corresponding to: 6mm < d < 10mm
For actuation directions 2 and 3, place the sensor and actuator facing each other with the
centering marks at a distance d corresponding to: 2mm < d < 10mm
At the end of the assembly, plug the supplied caps into the housing of the fixing screws
as shown in the assembly diagram. These plugs reduce the risk of tampering with the product as indicated in the EN ISO 14119 standard.
Figure 14 – Actuation direction
For each type of installation, check carefully that the sensor activation side lobes do not
cause an unintentional activation (-> “Areas of electromagnetic interference”).

8541613 – 12/01/2023 – Rev.0
RFID SAFETY SENSOR
Figure 15 – Assembly Areas of electromagnetic interference The side lobes of the sensor field may influence the transponder behavior, depending on the actuator position.
To avoid influence of the side lobes, observe the specified distances between sensor and
actuator.
Figure 16 – Detection field of the sensor
Multiple systems With applications involving multiple sensors mounted close together, a minimum distance L = 150mm between the sensors must be observed in order to avoid interference (Figure 17).
8541613 – 12/01/2023 – Rev.0

RFID SAFETY SENSOR
Figure 17
With gate closed, make sure that the SENSOR/ACTUATOR distance is Sao
(-> TECHNICAL SPECIFICATIONS).
With gate opened, make sure that the SENSOR/ACTUATOR distance is Sar (with a
protected area that does not present any danger to the operator) (-> TECHNICAL SPECIFICATIONS).
The nominal values of the OSSD’s switch-on and switch-off distances are stated assuming
a non-magnetic material support for the actuator and sensor. These reference values may vary depending on the support materials used.
At the end of the assembly, plug the supplied caps into the housing of the fixing screws
as shown in the assembly diagram. These plugs reduce the risk of tampering with the product as indicated in the EN ISO 14119 standard.

OPERATING MODES (R-Safe RFID Basic)
AUTOMATIC MODE
When the sensor is configured in “Automatic” the device behavior is the following: A safety gate opening (sensor/actuator distance > Sar) will deactivate the OSSD
outputs. At the safety gate closure (sensor/actuator distance < Sao) will reactivate the OSSD
outputs.

OPERATING MODES (R-Safe RFID Plus)
RFID SAFETY SENSOR
MANUAL MODE
Use in manual mode (start/restart interlock activated) is mandatory if the safety device
monitors a guard to protect a hazardous area and a person, after passing the guard, can stand in the hazardous area without being detected.
The RESTART control button must be installed outside the hazardous area in a position
where the hazardous area and the entire working area concerned are clearly visible.
Manual mode with EDM
R-Safe RFID can operate in MANUAL MODE using an external RESTART command.
A safety gate opening (reader/actuator distance > Sar) will deactivate the OSSD outputs.
At the safety gate closure (reader/actuator distance < Sao), to reactivate the OSSD outputs it will be necessary to press the N.O. RESTART button connected to 24VDC and release it.
The EDM input is only recognized as properly set if, after the sensor activation and after
setting the safety inputs, at least one valid start pulse is detected.
Use an external normally open pushbutton, whose temporary closure generates the
RESTART command (sequence 0 1 0).
The RESTART command must be connected in series with the K1/K2 control contacts of
the external contactors connected to 24VDC (pin 8).

At the safety gate closure (reader/actuator distance < Sao), to reactivate the OSSD outputs it will be necessary to press the N.O. RESTART button connected to 24VDC and release it.
Use an external normally open pushbutton, whose temporary closure generates the
RESTART command (sequence 0 1 0).
The RESTART command must be connected to 24VDC (pin 8).

AUTOMATIC MODE
RFID SAFETY SENSOR
Limitations concerning the use of Automatic mode
Use in manual mode (start/restart interlock activated) is mandatory if the safety device
monitors a guard to protect a hazardous area and a person, after passing the guard, can stand in the hazardous area without being detected.
Automatic mode with EDM
In “Automatic mode with EDM”, the “EDM input” terminal must be connected to 24VDC
through N.C. K1/K2 contact (in this way monitoring of the external contacts is enabled).
A safety gate opening (reader/actuator distance > Sar) will deactivate the OSSD
outputs.
The safety gate closure (reader/actuator distance < Sao) will reactivate the OSSD
outputs only if the EDM signal is correct.
The following figure shows the connections to perform in order to enable the
monitoring of the K1/K2 external contacts.

The time allowed to elapse from the activation of the OSSD outputs and the opening of
the FBK contacts must be t <500ms (Figure 23).
Figure 23 – Correct EDM timing Automatic mode without EDM When the sensor is configured IN “Automatic without EDM” the monitoring of external K1/K2 contacts is disabled, the “EDM input” must be connected directly to +24VDC. A safety gate opening (reader/actuator distance > Sar) will deactivate the OSSD
outputs. At the safety gate closure (reader/actuator distance < Sao) will reactivate the OSSD
outputs.

INPUT/OUTPUT
SAFETY INPUTS (R-safe RFID Plus only)
INPUT1 / INPUT2 R-Safe RFID Plus is equipped with two PNP active high safety inputs. The INPUT1 / INPUT2 input are used to receive the external OSSD’s signal from another sensor (when a serial connection is requested).
EXTERNAL DEVICE MONITORING / RESTART The EDM/RESTART input is used to monitor the feedback connection of any external contactors (connector pin 8). This signal is PNP active high.
STATUS OUTPUT
The system has a status digital output with the following characteristic: PNP active high, 0 … +24VDC Maximum load: 100 mA Overload protection
The Status output gives real-time information of the passive RFID actuator presence.
When several RFIDs are connected in series, please refer to the “SERIAL MODE” section
for the use of the STATUS output.
The status output has no safety-related function.
OSSD SAFETY OUTPUTS
Two static outputs (connector pin 4 and 7) are provided, based on the C-type interface for which functional safety aspects are ensured by an internal dynamic test (ZVEI Classification – CB24I).
