Özel gereksinimler
Ekstrem hava koşulları, ince toz veya çok titreşen makineler ve tesisler: örneğin madencilikte konveyör teknolojisinde karşılaşılan zorluklar çok fazladır. Konveyör sistemleri bazen kilometrelerce uzanır ve ıslak veya tozlu olabilecek malzemeleri ve ham maddeleri güvenilir bir şekilde taşımalıdır. Bir konveyör eşit olmayan şekilde yüklenirse veya bant artık makaraları arasında hizalı değilse, bandın düzeltilmesi veya konveyörün derhal durdurulması gerekir.
Diğer birçok endüstri dalında, konveyör teknolojisi de üretim ve yüklemenin önemli bir parçasıdır ve bu nedenle çeşitli uygulamaların verimliliğine önemli ölçüde katkıda bulunur. Özellikle otomasyon teknolojisi alanında güçlü bir şekilde büyüyen uluslararası rekabet nedeniyle, çoğu alan üretim süreçlerini optimize etmek için büyük bir baskı altındadır. Bu, konveyörlerin güvenilirliğini ve ayrıca bir sorun veya tehlike meydana geldiğinde doğrudan ve güvenli bir şekilde durdurulabilmelerini daha da önemli hale getirir.
Konveyör teknolojisini korumak için şalter cihazları
Uygulama alanı ve söz konusu endüstri dalına bağlı olarak, şalter cihazları farklı konveyör sistemlerinde ve çok zorlu ortamlarda kullanılabilirken aynı zamanda güvenlik, korozyon direnci ve sağlamlık gereksinimlerini karşılamalıdır. steute'nin acil durum halatlı şalterleri, örneğin daha büyük tesislerde güvenilir acil durdurmaları ve kayış kopması izlemeyi kolaylaştırır. Bant hizalama şalter, konveyör bantlarının doğru hizalanmasını izler ve böylece ağır dökme yüklerin taşınmasını güvence altına alır.
Güvenlik ürünlerine ek olarak steute, üretim süreçlerinin otomasyonunu ve optimizasyonunu destekleyen çok çeşitli şalter ve sensörler sunmaktadır. Örneğin, kablosuz sensörler ve konum şalterleri, üretim süreçlerinde parça malların otomatik sayımı ve izlenmesi için esnek bir şekilde kullanılabilir.

Emergency-stop function with robust emergency pull-wire switches
The emergency pull-wire switches in our ZS 92 S series were developed especially for extreme environments and applications. They are optionally available with a very robust die-cast aluminium enclosure with multiple coatings (passivation, primer, powder coating) or alternatively a high-quality thermoset enclosure. Our range includes 2G/D variants for Ex zones 1 and 21, as well as 3D variants for Ex zone 22.
The ZS 92 S emergency pull-wire switch assumes the emergency-stop function along conveyors, can be actuated at any point along the wire and contributes significantly to personal and machine safety.
Arka ve alt kısımdan montaj imkanı
The ZS 92 S series can be mounted both from the rear and from below. The mounting dimensions are compatible with other emergency pull-wire switches on the market, simplifying retrofitting or replacement within existing conveyor systems.
Optionally available as a Dupline safe variant
The ZS 92 S emergency pull-wire switch is optionally available with an integrated 8-pole Phoenix multi-way connector and bracket for safety bus module. The safety bus module is available as an accessory in different versions and facilitates connection to the “Dupline safe” protocol.
Extremely flexible thanks to various settings
The ZS 92 S emergency pull-wire switches are available with different settings for the release lever and unlocking mechanism. They can therefore be installed more or less anywhere.
LED sinyal ışığı
The ZS 92 S emergency pull-wire switch is optionally available with an LED indicator lamp. This lamp lights up red when the emergency pull-wire switch is actuated, making it possible to see immediately where along the conveyor belt the stop was initiated and intervention is required.
Comprehensive and innovative accessories for emergency pull-wire switches
Emergency pull-wire switches are crucial to safety in plants with industrial conveyors. They facilitate the triggering of an emergency stop anywhere along the belt. But in order to exploit the full potential of these switches and adapt them to individual requirements, it is vital to have the correct accessories. In the following, we will present a few tried and tested accessories which can increase the functionality and flexibility of emergency pull-wire switches.
Kurulum karşılaştırması: gerdirmeler ve tel kelepçeler vs. tel gergisi TS 65
TS 65 wire tensioner - quick, easy, efficient!
Fewer steps, more efficiency! Our expert Matthias Schara challenged himself at the Rhein-Umschlag gravel works to perform an installation contest: the widespread conventional method of pull-wire installation using turnbuckles, cable clamps and thimbles against state-of-the-art installation using the innovative TS 65 wire tensioner from steute. The result: the complete pull-wire installation took over 9 minutes versus just 42 seconds! The TS 65 wire tensioner not only saves a considerable amount of time, but also significantly reduces the number of necessary steps and tools.
Perfect team
Particularly in plants where many switching devices are installed, the factors time and ease are very much a focal point. Holding on to conventional methods can hinder efficiency. For simplifying installation and saving not only time and money, but also manpower, the combination of a ZS 92 S pull-wire switch and a TS 65 wire tensioner is unbeatable.

Position monitoring of conveyor belts using freely adjustable belt alignment switches
The belt alignment switches in our ZS 92 SR series are true specialists when it comes to extreme environments. All products in this series feature outstanding mechanical robustness and come either in a die-cast aluminium enclosure or a thermoset plastic enclosure (-KST). Also available are the Ex ZS 92 SR-2D (for dust Ex zone 21) and the Ex ZS 92 SR-3D (for dust Ex zone 22), both in a die-cast aluminium enclosure.
Our belt alignment switches monitor the straight course of conveyor belts. A large stainless steel roller lever swings to one side if the belt is no longer aligned between the rollers, for example because it is unevenly loaded. Depending on the control settings, this can either enable a correction of the belt or stop the entire conveyor. Its robust construction and special design for extreme environments make the ZS 92 SR series a reliable solution for complex applications.
Staggered contacts facilitate advance warning to enable timely belt correction
A truly outstanding feature is staggered contacts with individually adjustable switching points. The switching points for advance warning and for shutting off the conveyor can each be set within a range of 5°-35°. All that is necessary is a simple unlatching, shifting and relatching of the switch inserts. The switch can then first send an advance warning, and only if the lever swings out further will the conveyor shut down. These "advance warning contacts“ reduce standstills: the operator has a chance to intervene before the belt stops.
Different variants for roller lever adjustment
Some variants have a self-locking shaft (positive engagement), enabling the shaft to be changed quickly, while others have a continuously adjustable shaft, enabling the the default position of the roller lever to be adjusted to the individual application case.
LED sinyal ışığı
The ZS 92 SR belt alignment switch is optionally available with an LED indicator lamp which displays the switching state. This makes it possible to see along the conveyor from a distance where exactly the belt is no longer aligned.
Innovative wireless solution for belt alignment monitoring
Combining our tried-and-tested ZS 92 SR belt alignment switch with a separate RF I/O radio module has opened up new possibilities for efficient and interference-free conveyor control. Using sWave technology, a transmitter unit sends the signals coming from the switch to a wireless relay component which functions as a receiver. The transmission functions reliably and without cables over distances of up to 400 metres in the field. Additional repeaters can be installed for greater distances.
This robust wireless switching system has considerable benefits, especially in adverse environments, and unites the core steute competences switchgear and wireless technology.
Innovative belt-rip detection system
Do not let a simple rip in your conveyor belt lead to catastrophic failure and costly downtime. The ZS 71 belt rip detection switch and wire system can safeguard your operations by providing early detection and swift action. With its belt-rip features, robust construction, and user-friendly design, the ZS 71 belt-rip detection switch offers peace of mind and uninterrupted productivity. The ZS 71, combined with the comprehensive wire kit, offers a complete solution for belt-rip detection. When a rip occurs in the belt, any material or ripped section of conveyor belt caught by the wire activates the switch, halting the conveyor operation.
With its quick detection and immediate action upon belt rip occurrence, the switch significantly minimises conveyor system downtime, saving you valuable time and resources. The ZS 71 belt-rip detection switch is compact and designed to fit perpendicular to the conveyor belt, even in restrictive spaces.
