The heavy-duty incremental rotary encoders from Pepperl+Fuchs are designed to work reliably in harsh conditions—for example, in outdoor process plants or in construction machinery in dusty, dirty environments. Due to their robust design, the heavy-duty rotary encoders easily withstand heat, cold, dirt, constant vibrations, strong shocks or electromagnetic interference. As a result, they deliver precise measurement results at all times. This makes them the ideal solution, e.g., for speed feedback in large asynchronous motors.

Sensor technology that is used in hazardous areas needs to fulfill special requirements. The incremental rotary encoders for these areas are therefore available with EU-type examination certificates up to Zone 1, including flameproof enclosure (Ex d) and intrinsically safe (Ex i) types of protection. Their robust housing design increases service life and reduces maintenance work. Whether in the chemical industry, in wastewater treatment plants or in power plants: Wherever explosive atmospheres can form, incremental rotary encoders from Pepperl+Fuchs ensure safe process operations.

Particularly high hygiene requirements are placed on sensors used in the pharmaceutical, chemical or food industries. For this reason, Pepperl+Fuchs has developed an incremental rotary encoder with a hygienic design: The sensor's stainless steel housing is designed to meet hygiene requirements and ensure microbiological safety in accordance with EHEDG. In addition, the rotary encoder is insensitive to aggressive chemical cleaning agents and disinfectants. Due to its resistance to thermal shock, it can be easily cleaned with high-pressure equipment. These features shorten cleaning times and therefore increase machine availability.
