Position and safety switches
SIRIUS position and safety switches handle the precise detection of motion sequences in machines and plants in just about all applications. Whether they are used to detect positions, limit the movement of specific machine components, monitor the position of movable protective devices, or are incorporated in safety circuits according to EN ISO 14119 – our mechanical switches and non-contact sensors are able to manage the wide range of information in the field, even under the harshest conditions.
No scope for manipulationCapturing a wide variety of information, such as motion sequences and conditions in the field, requires precise devices on which one can rely: SIRIUS position and safety switches – for virtually any application in the field. They offer reliable shutdown of machines and plants in fault or hazard situations, even in extreme ambient conditions.
Communication via AS-Interface: flexible from end to endThe SIRIUS 3SF1 position and safety switches are suitable for networked systems as they can be connected to AS-Interface. The operating state is shown via the LEDs on the AS-i switches, thereby facilitating troubleshooting and saving time.
Quick and easy connection to the AS-i network:
- No additional wiring as the entire ASIsafe electronics are integrated in the enclosure
- Via M12 connector, 4-pin
- Low loading of the data line (170 mA max. current consumption of the magnet) through direct integration of safety switches with tumbler
- 3SF13...-1BA4 position switches are suitable for series connection for protective door tumblers as they fulfil the high safety category SIL 2 / PL d in addition to the ASIsafe standard. A special logic enables the required double evaluation of the actuator within the switch. This enables the machine to be restarted quickly by unlocking the magnet, without opening the protective door.

Safe system technology from the sensor to the field module
The PROFIsafe connection for the cabinet-less setup directly at the machine is possible via the compact block I/O SIMATIC ET 200eco PN with PROFINET connection.
The same PIN assignment on the modules, connection cables and sensors enables simple and fast connection and eliminates the risk of confusion and its consequences.
The configurator allows easy selection of the best device for each application from this comprehensive range of position and safety switches. For example, if you already know the order data for a device, and simply require a data sheet or the CAD data, just enter the order number into the appropriate field (direct input complete or components) and you will receive the desired information.
