■ Overview
The 3SF1 hinge switches with safety-oriented communication
can be directly connected using the AS-Interface bus system.
The safety functions no longer have to be conventionally wired
up.
With the 3SF1 position switches the ASIsafe electronics are
integrated in the switch enclosure.
The hinge switches are provided for mounting on hinges.
There are two actuator variants here:
• Hollow shaft, diameter inside 8 mm, outside 12 mm
• Solid shaft, diameter 10 mm
For the ASIsafe version of the hinge switch, the basic switch and
actuator head must be ordered separately. The basic switches
correspond to the position switches of the standard version (only
use versions with snap-action contacts).
The standards and approvals are the same as for the 3SF1
position switches (see page 6/15).
