■

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.
