Automation is our world. A perfect application solution is our goal. A willingness to take entrepreneurial risks, a pioneering spirit, and a firm belief in their own inventive powers – these were the assets that Walter Pepperl and Ludwig Fuchs started out with when they opened their Mannheim radio repair shop in 1945. Their invention of the proximity switch a few years later proved their strength. It was also the starting point in a successful history defined by close customer relationships as well as innovative automation technologies and procedures. Then as now, our focus is directed...

The Explosion Protection Types Explosion protection can be achieved in various ways. It depends on factors including the type of facility and system and the physical preconditions. This section explains four processes used in electrical explosion protection equipment and solutions from Pepperl+Fuchs. The traditional electronic explosion protection. The supply to the electrical equipment is fed through a safety barrier that limits the current and voltage so that the minimum ignition energy and ignition temperature of an explosive mixture are not reached. Switching equipment and controls are...
