Electronic Emergency Stop SEU 3/4

Whether on the conveyor belt or on the machine – when maximum safety is required, BERNSTEIN rope pull switches provide a proven and reliable technical solution.The switches can be deployed flexibly, are easy to install and convenient to handle.And most importantly: they offer maximum safety when it is needed. The SR series of safety rope pull switching devices are designed and approved in accordance with the standards IEC 947-5-5, DIN EN 60947-5-5 and ISO 13850. On actuation or in the event of cable breakage, the emergency stop switching device locks automatically and can only be reset to its initial setting by using the resetting device on the switch. • Protection class IP67 • Stable and durable plastic housing (PA 6 GV) • Can be deployed at temperatures between –25 °C and +70 °C • Flexible handling with three M20 x 1.5 cable entries • Easy installation due to the maximum connection space • Up to four positively driven NC contacts

When it comes to maximum safety on the assembly line, in the production line, or directly at the machine, the Safety Rope Pull Switches from BERNSTEIN AG are a reliable and proven solution. BERNSTEIN has added a particularly small and compact version to the product family of safety rope pull switches. Thanks to its modular design, the SRO (Safety Rope Pull) is extremely space-saving as well as being highly versatile. The modular principle has the advantage of always being able to offer exactly the right product for a specific customer application.

Mechanically highly stressed components – such as the rotating head – are made of metal. This makes it extremely robust and durable. The plastic housing, on the other hand, is light and functional. A variant with M12 plug connector allows a particularly simple connection to the machine. Another user-friendly feature is the possibility of flexible contact assembly: The contact combination of NC and NO for monitoring the door position and the guard locking can be freely combined at the factory. MANY FEATURES AT A GLANCE • Lightweight yet robust: Hybrid of metal and plastic • Flexible contact assembly • Integrated manual release • Symmetrical design • Five actuating positions • Rotatable head ( 4 × 90° ) • Fail-safe guard locking system • Optional emergency release • Optional escape release • M12 connector as an option

The SRF (Safety RFID) is a non-contact safety sensor, that monitors moveable safety guards, such as doors, flaps and hoods. With its innovative diagnostic system, the SRF makes safety circuits suitable for Industry 4.0. The system provides a multitude of diagnostic data of each sensor, even in a series connection, to support smart production. Diagnostic data is fed into the machine control system via I/O Link or alternatively displayed on a smartphone by way of NFC technology. In this way, 20 different diagnostic information of each sensor can be retrieved and made available. This diagnostic data delivers cost-effective predictive maintenance in a simple way. Through its advanced fault recognition capability, costly machine shutdowns can be prevented. This way, your machinery and plant will work even more efficiently!
