3SF2 cable-operated switches for AS-Interface
4
■
Overview
SIRIUS cable-operated switches are used for monitoring or for
EMERGENCY-STOP devices on particularly endangered system
components.
AS-Interface cable-operated switches can be directly con-
nected via the bus system AS-Interface with safety-related com-
munication. The safety functions no longer have to be conven-
tionally wired up.
As the effective range of a cable-operated switch is only limited
by the length of the trip-wire, large systems can also be pro-
tected.
Standards
The switches with positive latching are suitable for operation
in EMERGENCY-STOP devices according to EN ISO 13850.
They can achieve up to category 4 according to ISO 13849-1 or
SIL 3 according to IEC 61508.
