■

Overview

SIRIUS cable-operated switches are used for monitoring or for

EMERGENCY-STOP devices on particularly endangered system

sections.

AS-Interface cable-operated switches can be directly con-

nected via the bus system AS-Interface with safety-oriented

communication.

The safety functions no longer have to be conventionally 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 in according to ISO 13850. They

can be used up to category 4 acc. to ISO 13849-1 (EN 954-1) or

SIL 3 acc. to IEC 61508.
