Euchner Precision Multiple Limit Switches

1 More than MultipleLimit Switches2 Quality, reliability, precisionQuality, reliability and Precision are thehallmarks of our corporate represent concepts and valuesto which we feel totally committed. At Euchner , quality means that allour employees take personal respon-sibility for the company as a wholeand, in particular, for their own field ofwork. This individual commitment toperfection results in products whichare ideally tailored to the customers needs and the requirements of themarket. After all: our customers andtheir needs are the focus of all ourefforts. Through efficient and effectiveuse of resources, the promotion ofpersonal initiative and courage in find-ing unusual solutions to the benefit ofour customers, we ensure a high levelof customer satisfaction.

2 We familiar-ize ourselves with their needs, require-ments and products and we learnfrom the experiences of our cus-tomers own More than made by EUCHNERMore than the world the Swabianspecialists in motion sequencecontrol for mechanical and sys-tems s history began in 1940 withthe establishment of an engineeringoffice by Emil Euchner . Since thattime, Euchner has been involved inthe design and development of switch-gear for controlling a wide variety ofmotion sequences in mechanical andsystems engineering. In 1953, EmilEuchner founded Euchner + Co., amilestone in the company s history. In1952, he developed the first multiplelimit switch to this day a symbol ofthe enterprising spirit of this family-owned Safety ManMachineToday, our products range fromelectromechanical and electroniccomponents to complex system solu-tions.

3 With this wide range of productswe can provide the necessary tech-nologies to offer the right solution forspecial requirements regardless ofwhether these relate to reliable andprecise positioning or to componentsand systems for safety engineering inthe automation products are sold through aworld-wide sales network of compe-tent partners. With our closeness tothe customer and the guarantee ofreliable solutions throughout theglobe, we enjoy the confidence of cus-tomers all over the world.

5 A high standard ofquality is guaranteed in every installation position by the degreeof protection IP Multiple Limit Switches possess several switching ele-ments arranged in a row. The spacing between the individualswitching positions of 12 mm and 16 mm is standardized inaccordance with DIN 43697. The product range is completedwith a particularly compact, space-saving version with a spa-cing of 8 switching elements are actuated by means of is achieved with trip dogs in accordance with DIN 69 639,which are mounted with an interference fit in trip rails accor-ding to DIN 69 638 (see separate catalogue Trip Dogs and TripRails).

6 DesignDepending on the technical requirements in terms of operatingpoint accuracy and approach speed, four functionally differenttypes of plunger (chisel, roller, ball and dome plungers) are on the plunger type, the reproducible operating pointaccuracy is mm and the maximum approach speed is120 Precision Multiple Limit Switches can be assembled with snap-action and safety switching elements, or also in combinationwith inductive switching elements. The mechanical life of theswitching elements amounts to 30 x 106 mechanical uses the high-quality and proven acrylonitrile-butadienerubber (NBR) for all seals and sealed areas. This material isresistant to oils, greases, fuels, hydraulic fluids and most knowncooling lubricants.

7 Moreover, NBR possesses high mechanicalrigidity over a wide temperature range and is therefore ideal forthe highly stressed diaphragm seal, which separates the plungercompartment and the interior of the material used for the diaphragm seal is a decisive criterionfor the quality, mechanical life and Precision of Euchner Precision Multiple Limit Switches . The same material is used forthe cover seal and the cable series with an exterior diaphragm which is designed to resistthe effect of resinous cooling lubricants is also available. Thisversion prevents the plungers further variant with an interchangeable plunger guide allows aquick and easy plunger replacement without any re-adjustmentof the Multiple Limit switch.

Plunger sticking isprevented and it is not necessary to replace the switch or technical data on this series see pages 20 and series RGCS with its interchangeable plunger guide allowsquick and easy plunger replacement without any new adjustmentof the Multiple Limit switch.

Specialist knowledge is not required. It isnot necessary to make changes to the machine installation orperform time-consuming re-adjustment of the this way, repair costs are reduced and the machine downtimesare minimized.
