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.

Highlights at a glanceCapturing 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 end
The 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.
- 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.
Safety wiring in the field with IP 65/67
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.
