One switch platform, multiple applications

The basis of the new platform is the standardised enclosure concept, which is available in two versions: plastic (Duroplast) and grey cast iron. The plastic version is resistant to aggressive media and suitable for port logistics applications and loading and unloading operations, as well as in the agricultural industry in the processing of fertilisers, minerals and phosphates, plus a wide range of other applications. The cast iron version is suitable, for example, in mining, bulk materials and extraction. 

The function range is also divided into two basic versions: the emergency-stop, designed as a pull-wire switch, and the position monitoring. The basic switch on the position monitoring version can be flexibly combined with a range of actuation elements. Typical application areas include emergency-stop deactivation, belt misalignment monitoring in the transport of bulk materials, end position monitoring in steel making and level monitoring in material silos.

The protection types IP66 and IP67 create the prerequisites for switchgear use in extreme environmental conditions. 

All basic versions can be optionally connected to the Dupline installation bus or the AS-I-Safety-at-Work for quick and easy networking, series switching and improved transfer of diagnostics data. Central connecting terminals with CAGE and CLAMP technology also help to reduce installation times. 

All switchgear satisfies the requirements of a safety switch, plus the HDS platform has a range of international approvals, including CE (Europa), UL (USA), CCC (China), EAC (Russia), Ex, IECEx (explosion protection, international) and INMETRO (Brazil, South America). 

"With the modular HDS switchgear platform, we’ve created a product that our customers can use flexibly over a wide range of applications. The HDS platform can also be used worldwide thanks to its international approvals," explains Udo Sekin, heavy industry sector manager at the Schmersal Group. "The product will also help machine manufacturers to market their systems around the world."
