Leine & Linde Encoders

Leine & Linde Encoders are the first encoders available on the world market to be certified according to new international directives.

Leine & Linde is the first manufacturer of incremental encoders a component commonly used in drive systems that was able to certify rotary incremental encoders in the 841-series according to the new international IECEx directive. An Ex area can be known by different names such as “Hazardous Locations”, “Hazardous Areas”, “Explosive Atmospheres”, and the like and relate to areas where flammable liquids, vapors, gases or combustible dusts are likely to occur in quantities sufficient to cause a fire or explosion.

A “three-zone model” in many countries, including those of the European Union, characterizes potentially explosive areas. This model is defined by zone 2 indicating an area in which there is rarely an explosive atmosphere, zone 1 indicating an area in which there are sometimes explosive atmospheres, and zone 0 for an area in which there is always or frequently an explosive atmosphere. The robust and versatile 841-series encoders manufactured by Leine & Linde have been approved for zone 1 with a f lameproof enclosure “d” type of protection. Some commonly classified Ex areas where encoders are used can be found in: Automotive refueling stations or petrol stations, oil refineries, rigs and processing plants, chemical processing plants Printing industries, paper and textiles, Hospital operating theatres, Aircraft refueling and hangars, Surface coating industrie, woodworking areas, sugar refineries, metal surface grinding, especially aluminum dusts and particles.

Because many Leine & Linde customers are operating systems in such areas all over the world, the company has been striving for and has received certification according to the new global standards, IECEx.
