■ Overview
AS-Interface cable-operated switches can now be directly
connected via the standard AS-Interface with safety-oriented
communication.
The safety functions no longer have to be conventionally wired
up.
■ Application
SIRIUS cable-operated switches are used for monitoring or for
EMERGENCY STOP devices on particularly endangered system
sections.
As the effective range of a cable-operated switch is only limited
by the length of the pull-rope, large systems can also be pro-
tected.
Standards
The switches with positive latching are suitable for operation
in EMERGENCY STOP devices in according to EN ISO 13850.
They are usable up to Category 4 according to EN 954-1.
