With the RSS 16 is the Schmersal group Introducing a safety relay that offers designers and operators the "best of both worlds". The housing will appear familiar to the user of electromechanical safety switching devices. It has the same dimensions as the AZ 16 safety switch, which is used millions of times. Unlike the AZ 16, the RSS 16 has no mechanical actuator. The target is identified without contact using the RSS technology: An RFID signal that has been improved in terms of safety takes over the communication between sender and receiver.
This technique creates the prerequisite for the user of the RSS 16 to be able to choose between three different coding variants. In the basic version, the sensor accepts any suitable target. A second version only accepts the target that was taught-in the first time it was switched on. Finally, there is a third variant in which the Programming procedure can be repeated as often as you like.
Thus, the coding and thus also the manipulation protection can be adapted to the application and the degree of manipulation incentive. This procedure is described in the new ISO 14119. According to the new classification of this standard, the RSS 16 safety sensors are "4" non-contact and coded locking devices.
With the RSS 16 the target can be approached from three sides - this allows a high degree of flexibility in the integration into the surrounding construction. In addition, the safety sensor can be used as a magnetic stop, so that the designer can do without a separate stop with detent. The terminal compartment provides additional flexibility during installation. For example, the user can inexpensively and tailor a series circuit from switch to switch. It also achieves performance level e according to EN 13849 and the serial diagnostic function provides important operational information that can be used for diagnostic purposes.
The RSS 16 can be exchanged for existing 1: 1 designs against the AZ 16. By eliminating the mechanical actuators eliminates interference contours that are difficult to clean. In addition, the system works wear-free and with a high tolerance for safety gate offset. Users who want to continue to use an electromechanical safety switch, without sacrificing the increased protection against manipulation, can order a custom coded version with the AZ 16ZI.
