The 3SF1 position switches with safety-related communication can be directly connected using the AS-Interface bus system. The safety functions no longer have to be conventionally wired up.

3SF1 position switches with integrated ASIsafe Electronics

With the 3SF1 position switches the ASIsafe electronics component is integrated in the switch enclosure.

Connection to the AS-Interface is by means of a 4-pole M12 connector socket (plastic version) connected to the yellow AS-Interface bus cable.

The wide enclosures (50 or 56 mm) also have an M12 socket for connecting a second position switch. Category 4 according to
EN ISO 13849-1 is thus achieved.
