RFID switch - Non-contact safety switches
In industrial installations, numerous different switches can be found. Since 2015, secured access to machines must comply with the EN ISO 14119 standard. Each door, valve, or protective cover requires its own construction, assembly, and security.
Checking status with safety sensors
Safety sensors, also known as non-contact safety switches, monitor the status of a door, valve, or protective cover for safe access/switching.
RFID safety switch
RFID safety switches communicate based on radio waves (radio-frequency identification) and are therefore non-contact. RFID switches are uniquely coded and cannot be manipulated, enabling a high level of security. The transponder (transmitter) transmits a magnetic field to the receiver (receiver). The transmitted signal is received by the receiver and, depending on the switching distance (the minimum distance between transponder and receiver), the safety switch is closed. ReeR Safety and Mechan Controls are specialists in the field of non-contact switching.
R-SAFE series non-contact safety switches
The R-SAFE series of non-contact safety switches use RFID technology to communicate with authorised actuators. This system helps prevent machines and/or equipment from being activated if no authorised RFID actuator is present near the sensor, for example, when a cover or door is not yet (properly) closed.
Standard and Slim actuator
The R-SAFE series of non-contact safety switches are available with a standard or a slim actuator. The standard actuator measures 28.5 x 42 x 18 mm, while the slim actuator measures 9 x 52 x 18 mm. Due to its slimmer design, the slim actuator is particularly suitable for applications where space is limited.
Three versions for different applications
Both the standard and slim R-SAFE switches are available in three variants, each with specific features to meet various safety requirements:
- Basic: Automatic restart; no series connection.
- Pro: Automatic restart; series connection of up to 16 switches with individual status reading.
- Plus: Automatic and manual restart; series connection of up to 16 switches with individual status reading.
All sensors are available with a connector (M12), a pigtail (15 cm with M12 connector), or a cable (1, 3, 5, or 10 metres).
Mosaic Safety Designer (MSD) software
These switches are mechanically compatible with other RFID safety sensors from ReeR Safety, such as the Magnus RFID and Magnus MG "S" series. They can be seamlessly integrated with ReeR's modular safety PLC, Mosaic. Using the Mosaic Safety Designer (MSD) software, users can easily design, configure, and manage safety systems, enhancing the flexibility and scalability of safety solutions.
Unique read-out capability with R-SAFE
The R-SAFE series stands out due to its ability to read the status of up to 16 RFID sensors on the Mosaic safety PLC using just a single wire (Pro and Plus versions only). In other systems, each switch requires a separate wire to the controller, leading to increased cabling and a more complex installation process.
Splitters for series connection
Splitters are used to facilitate the series connection of multiple safety switches.
- Plus series: The Plus series uses the CRY12-S1 and CRY12-S2 splitters. The S1 splitter connects the safety PLC to the first RFID sensor, while the S2 splitter links the subsequent sensors together. This setup reduces unnecessary wiring and ensures faster installation.
- Pro series: The Pro series uses the CRY-A, CRY-B, and CRY-C splitters. The CRY-A splitter allows the sensor’s status signal to be read, while the CRY-B splitter enables the series connection of sensors, and the CRY-C splitter provides an option to add an extra power supply if needed. Finally, the CRY-TP termination unit is available to complete the series connection.

RSSG-SS RFID safety switches (Stainless steel)
ODNK series RFID safety switches OSSD - PL-e
The ODNK series (uniquely coded RFID with 4 billion possible code combinations) from Mechan Controls are state-of-the-art OSSD safety switches. They use the latest safety technologies for maximum reliability and safety.
The non-contact switches are designed to operate standalone or can be connected to safety relays or safety controllers to fit perfectly into your safety system. Up to 30 O-Type switches can be connected in series while maintaining safety level PL-e in accordance with EN ISO 13849-1.
RFID security switch - 4,000,000,000 unique codes
The RSS series safety switches from Mechan Controls are unique because they use volt-free contacts. You are not required to use relays or other safety components from Mechan Controls, but you can also connect the RSS series safety switches to the programmable safety relay from ReeR Safety.
The safety switches are individually coded and suitable for high security applications for securing machines. The RSS series is available with a IP69K seal rating for use in humid, heavy and dusty environments.
Volt-free contacts
Unlike other RFID switches on the market that use OSSD, the Mechan controls RSS series is unique because it uses voltage-free contacts, which means you are free to choose your safety relays.
The RSS series offers extra security by using 4,000,000,000 unique codes to safety category 4 according to safety standard EN 14119.
Features RFID Contactless safety switch - Mechan Controls
RFID safety switches from Mechan Controls are unique safety sensors and have the following characteristics:
- IP67 and IP69K seal
- Housing: ABS filled with resin
- 4,000,000,000 unique codes
- EN 14119 type 4, high
- Equipped with an LED monitoring indication
