1 PRECISION SWITCHESPRECISION SWITCHESCONTENTSL imit SWITCHES to EN50041 EUCHNEREUCHNERP recision SwitchesThe Teknic EUCHNER Limit Switch PRECISION , Reliability and Teknic EUCHNER Limit switch is a versatile unit, according to the EUROPEANSTANDARD EN 50041 with EUCHNER know how and is further developed toproduce a perfect universal construction and the exclusive use of high quality corrosion resistant materials, preci-sion finishing and the high Protection class lP67 to IEC 529, DIN 40 050 are the guarantees fora trouble free and reliable operation under the most arduous arm or plunger actuation, 7 different actuator designs, which can be set at 4 X 90 about the longitudinal axis and the choice of switching direction setting (with leverarm actuation) offer the user an almost unlimited possibility for individual Limit Switch in Detail Cross Section of an Excellence in Plunger plunger actuated versions allow the user a choice of 4 different types.

2 The stainless steelhardened plunger with telescopic action is precisely guided within anodized die-cast light alloyhead, and is practically maintenance free. This plain bearing principle which is designed formany millions of operations, and is also incorporated in our PRECISION multiple limit SWITCHES ,ensures the exceptional reliability of the Teknic EUCHNER limit switch. The direction of theactuator head can easily be changed in steps of 90 Diaphragm SWITCHES with plunger actuation, the plunger area is separated from the switch chamber by adiaphragm seal made from NBR elastomer. Due to high demands the seal has a designedminimum life of 30 million operations and is therefore practically seal is firmly fixed to the plunger and is returned to the free position after each operation,not by the switching element but by the plunger return development of pressure due to plunger actuation is eliminated by a relief switching element is actuated by a metal cap pressed on to the point displacements (a logical consequence due to the high elasticity of the seal)

3 Aretherefore completely Lever arm ActuationThree different levers can be used on the lever arm actuated SWITCHES . The stainless steelshaft is precisely guided through a numerous adjusting possibilities give great flexibility:a) Adjustment of the actuator head around the longitudinal axis is possible in 90 Deg. Stepsb) Adjustment of the lever arm in positively fixed positions is possible in 90 Deg. Stepsc) Infinite adjustment of the lever arm within 360 ) Adjustment of switching direction, from the right only, from the left only orfrom both SWITCHESEUCHNERP recision SwitchesThe Edge lever arm actuated SWITCHES the actuating mechanism and the switch chamber is protectedagainst ingress of liquids by an edge seal which is made from NBR elastomer and is resistantto all known coolant and lubricating anodized die-cast aluminium housing has proved itself highly resistant to corrosion and isunaffected by even the most arduous conditions.

In order to meet this protection class, only highquality Teknic EUCHNER cable connectors with captive sealing rings should be element type ES510 Snap action double gap switching element with one NO contact and one NC gaps 2 x SwitchesDimensional DetailsLimit switch with roller lever arm in both directions.
