Sendix ATEX / IECEx encoders now available as hollow shaft versions for potentially explosive atmospheres

22 May 2015

Explosion protection is a particularly safety-relevant obligation of many industries and branches. In areas such as the mining industry, high plant availability and best protection possible for men and environment have highest priority. Here, the measuring devices in charge of positioning tasks must fully meet strictest protection regulations. 

As an encoder manufacturer, Kübler is offering a wide range of explosion-proof encoders. The position and motion sensor specialist is offering two different series. 

The series 70xx and 71xx. Both series include incremental, absolute, field bus encoders and encoders certified up to SIL3/PLe. Until now, both series were offering only solid shaft encoders. 
NEW: From now on, both series will be available both as solid shaft and as hollow shaft variants.

The hollow shaft version ensures optimal installation, in particular in tight mounting spaces. This type of mounting allows a smaller installation depth than solid shaft encoders. 

Thanks to their certifications, the Sendix ATEX / IECEx encoders can be used internationally. Its compliance with international standards allows Kübler's Sendix ATEX / IECEx encoder family to meet successfully the increasing market challenges. The 70xx / 71xx series of the Sendix ATEX / IECEx encoders covers a range of safety aspects.

Thanks to their flameproof encapsulated stainless steel housing in Safety-Lock™ design, they are approved for zones 1, 2, 21 and 22. Their wide temperature range of -40° to +60°C and their high IP67 protection level ensure reliable operation and highest safety against field breakdowns.

These features ensure the total saltwater resistance of these encoders, making them suitable even for offshore plants.

With its M2 certification, the 71xx series is approved and particularly suitable for use in the mining industry (above-ground/underground). This series decisively reduces the existing explosion hazard in this branch.   

The incremental encoders are available with a resolution reaching 5,000 pulses.  The absolute encoders offer a total resolution reaching 32 bits (singleturn max. 17 bits, multiturn 12 bits).  The absolute multiturn or singleturn encoders of these series are available with SSI, BiSS and field bus interfaces.
