Safety switch 3SF1

single-polestandardexplosion-proof

Capturing 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
