Pull-wire Switches

The EEx ZS 90 S guarantees that in a dangerous situation the operator can activate the emergency-stop function immediately from whereverhe is, over distances of up to 2 x 50 metres, without first having to run to the nearest emergency-stop button. The pull-wire is attached to a swing arm which latches closed in the emergency-stop position and can only be unlocked by moving a lever inside the enclosure. A typical feature of emergency pull-wire switches is their automatic pull-wire and tear-wire function: if the wire should tear or become dismantled, the device automatically switches off. With two normally closed contacts and two normally open contacts, it facilitates various switching options. A comprehensive range of accessories means that it can also be adapted to individual installations. The EEx ZS 90 SR is resistant to frequent knocks and bumps. And its ATEX/ IECEx certification means that it can be used in gas-ex-zones 1 and 2, as well as in dust-ex-zones 21 and 22.
