HDS: new heavy duty switch for heavy industry with approvals worldwide

05 March 2019

The Schmersal Group will be demonstrating its new HDS switchgear series for heavy industry at bauma 2019 in Munich, the specialist trade fair for the construction machinery sector. The modular series unites a range of functions into a single platform for the first time, making it suitable for an extremely wide range of applications. The basis of the new platform is the standardised enclosure concept, available in plastic (Duroplast) and grey cast iron.

The plastic version is resistant to aggressive media and especially suitable in 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 robust grey cast iron version is suitable for industries such as mining or 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.’
Visit Schmersal at bauma in Munich from 8 to 14 April 2019: Hall C2, Stand 305.
