Overview
The 3SF1 safety hinge switches with safety-related communica-
tion can be directly connected using the AS-Interface bus sys-
tem. The safety functions no longer have to be conventionally
wired up.
With the 3SF1 safety switches the ASIsafe electronics compo-
nent is integrated in the switch enclosure.
The hinge switches are provided for mounting on hinges. There
are two actuator variants here:
• Hollow shaft, inner diameter 8 mm, outer 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 standard safety switches (use only versions
with snap-action contacts).
The standards and approvals are the same as for the 3SF1
safety switches (see page 4/12).
