The TEKNIC EUCHNER - Limit Switch - Precision, Reliability and Versatility.

The TEKNIC EUCHNER - Limit switch is a versatile unit, according to the EUROPEAN STANDARD EN 50041 with EUCHNER know how and is further developed to produce a perfect universal construction. Robust construction and the exclusive use of high quality corrosion resistant materials, precision finishing and the high Protection class IP67 to IEC 60529, DIN 40050 are the guarantees for a trouble free and reliable operation under the most arduous conditions.

oLever arm or plunger actuation, 12 different actuator designs, which can be set at 4 X 90 positions about the longitudinal axis and the choice of switching direction setting (with lever arm actuation) offer the user an almost unlimited possibility for individual applications.

The Limit Switch in Detail - Cross Section of an Excellence in Design. The Plunger Actuation.The plunger actuated versions allow the user a choice of 5 different types. The stainless steel hardened plunger with telescopic action is precisely guided within anodised die-cast light alloy head, and is practically maintenance free. This plain bearing principle which is designed for many 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 the actuator head

ocan easily be changed in steps of 90 . The Diaphragm Seal.In switches with plunger actuation , the plunger area is separated from the switch chamber by a diaphragm seal made from NBR elastomer. Due to high demands the seal has a designed minimum life of 30 million operations and is therefore practically indestructable.The 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 spring. Any development of pressure due to plunger actuation is eliminated by a relief valve.The switching element is actuated by a metal cap pressed on to the seal. Switching point displacements (a logical consequence due to the high elasticity of the seal) are therefore completely eliminated. The Lever arm-Actuation.Three different levers can be used on the lever arm actuated switches. The stainless steel shaft is precisely guided through a housing.The numerous adjusting possibilities give great flexibility :

oa) Adjustment of the actuator head around the longitudinal axis is possible in 90 steps ob) Adjustment of the lever arm in positively fixed positions is possible in 90 steps.

oc) Infinite adjustment of the lever arm within 360 .d) Adjustment of switching direction, from the right only, from the left only or from both directions. The Edge Seal.In lever arm actuated switches the actuating mechanism and the switch chamber is protected against ingress of liquids by an edge seal which is made from NBR elastomer and is resistant to all known coolant and lubricating agents. The Enclosure.The anodised die-cast aluminium housing has proved itself highly resistant to corrosion and is unaffected by even the most arduous conditions. Cable connection can be made through TEKNIC EUCHNER Cable glands (Pg 13.5). The Cable connections.Each TEKNIC EUCHNER Limit switch to EN 50041 is tested before dispatch to the customer. It must comply with protection class IP 67. In order to meet this protection class, only high quality TEKNIC EUCHNER cable connectors with captive sealing rings should be used. Switching elements.Switching element type ES510.Snap action double gap switching element with one NO contact and one NC contact . Contact gaps 2 x 0.6 mm.

Limit switch with Indicator Lamps.All limit switches can be fitted with indicator lamps at operating voltages of 24 VDC or 220 VAC. The ordering code for limit switches with Indicator Lamps can be found against the ordering codes of individual types.
