For any machine requiring a fixed guard-door or cover, the YSR series ensures reliable state monitoring (door open or closed). Thanks to their serial connection capability, YSR types are particularly suitable for applications using multiple sensors, such as long packaging or assembly lines. These RFID-coded devices are classified type 4 according to ISO 14119.

RFID technology enables the user to assign a unique code to each sensor and actuator system, which greatly reduces the risk of tampering. YSR sensors can also be connected in series via the OSSD output and inputs, allowing up to 30 sensors to connect with just one relay or controller.

Since each sensor can provide individual feedback, it is possible to identify which guard-doors are open and which are closed. This is particularly useful when many sensors are connected in series.

The YSR series is part of a range of non-contact safety sensors used to monitor guard-doors, hoods or covers. Thanks to non-contact switching and coded RFID communication, the service life of these compact sensors is very long. Housings are ECOLAB-approved and rated to IP6K9K, making them suitable for washdown applications.

Safety level is category 4 according to ISO 13849-1.
