Wireless sensors replace cables

Whenever a high number of wireless switches and sensors need to be integrated in superordinate IT systems, wireless networks are the first and best choice. Typical applications include AGV fleets, but also E-Kanban racks for replenishment of small parts, e.g. at workstations in assembly halls. A new wireless sensor has now been developed for precisely this purpose.

Belt and braces: Ex protection and plant safety

Machine safety in explosive environments: when switchgear is required for this combined application, two different – and complex – sets of rules and standards have to be complied with, both of which make high demands on the products in question. Even though this field is a “niche within a niche”, users still have diverse options regarding their choice of safety switchgear and sensors, including the position switches with a safety function in the Ex 97 and Ex 99 series.
