SIRIUS 3SF1 Mechanical Safety Switches for AS-Interface
Safety Hinge Switches
3SF1, plastic enclosures, enclosure widths 31 mm / 50 mm
12
■
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 wired up conven-
tionally.
With the 3SF1 hinge 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 3SF1 position switches (use only versions with
snap-action contacts).
The provisions and approvals are the same as for the
3SF1 standard switches
(see page 12/91)
