EUCHNER’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 company.

Introduction
EUCHNER position switches are manufactured in accordancewith the European standard EN 50041. Robust construction andthe use of high quality corrosion resistant materials, precisionfinishing and degree of protection IP 67 according to IEC 60529guarantee trouble-free and reliable operation under the toughestconditions.
position switches - precise, reliable and versatile
Various EUCHNER position switch designs can be used as safetyswitches with certain switching elements whose NC contactsare positively opened by a rigid plunger, even if the switchingelement is damaged due to a broken spring or contact weld.Position switches with direct opening action contacts are usedin those cases where a guarantee of machine and/or humansafety is absolutely essential. Example: End travel positionswitching or an EMERGENCY STOP.

Position switch in detail
Plunger actuationThe plunger actuated versions allow theuser a choice of 6 different designs.The stainless steel hardened standardplunger with telescopic action (safety po-sition switches with direct opening actioncontacts have rigid plungers) is preciselyguided within the anodized die-cast alloyhead, and is almost maintenance free.The approach direction of the actuatorhead can be easily changed by 90°.
Lever-arm actuationDifferent types of actuators may be usedfor lever-arm actuation. The stainless steelshaft is guided precisely through thehousing.With the numerous adjusting options a highdegree of flexibility is given:
Approach direction adjustable by 4 x 90°Actuator direction for lever-arm actuationadjustable by 4 x 90°Switches to the left, or to the right, oron both sides
The housingWith their robust design, the die-cast alloyhousings have proven themselves highlyresistant to corrosion even under thetoughest conditions.Either the M20 x 1.5 cable gland or thepre-wired plug connector (straight or an-gled) may be used for the cable. The an-gled plug connector can be adjusted in 7directions around the longitudinal axis ofthe switch.
The diaphragm sealIn switches with plunger actuation, theplunger chamber and the switch chamberare separated by a diaphragm seal madeof NBR (acrylonitrile rubber). Because oftheir outstanding technical properties,NBR materials are used wherever possiblefor all mechanical and system engineeringapplications.The seal is firmly fixed to the plunger, andafter each switching operation it is retur-ned to the initial position by the plungerreturn spring and not by the switching ele-ment.Any build-up of pressure during plungeractuation is reliably prevented by a reliefvalve.The switching element is actuated bymeans of a metal cap pressed onto theseal.Switching point displacement (a logicalconsequence due to the high elasticity ofthe seal) is therefore completely elimina-ted.
The edge sealIn lever-arm actuated switches, an edgeseal protects the actuating mechanismand the switch chamber against dirt anddust. The edge seal, which is made ofNBR, is resistant to all known coolants andlubricants.
Cable connectionsBefore delivery to the customer, EUCHNERposition switches according to EN 50041undergo routine check tests for com-pliance with degree of protection IP 67.In order to obtain this degree of protec-tion, only high-quality metal cable glandswith captive sealing rings or the pre-wiredstraight or angled plug connector mustbe used.
Function displayPosition switches may be fitted with anLED on request. Voltage ranges of 10 to60 V AC/DC, 110 V AC and 230 V AC areavailable.

The large selection of actuator heads guaran-tees maximum flexibility and is suitable for avariety of applications.For example, the aluminum lever arm is usedfor high approach speeds and generous actua-ting mechanism tolerances.The domed plunger with its polished-groundsurface is designed for a high repeat accuracyof ± 0.002 mm.The ball plungers can be actuated from anumber of different directions.
Having removed the stainless steel mountingscrews, the actuator heads can each be adju-sted horizontally by 90°.

In the case of position switches with no safetyfunction, the lever arm can be adjusted conti-nuously. However position switches with a safetyfunction, can be adjusted by 90°.
Vertical adjustment 4 x 90°
On delivery, the lever-arm actuation is set toleft and right switching.If necessary, it can be set to right switching orleft switching only.

2) Snap-action contact elementThe snap-action contact element has a contact element which opens and closes regardless of its actuation speed.
3) H-contact bridgeThe design properties of the H-contact bridge (H-shaped) ensure that these switching elements reliably switch currents from 1 mA (e.g. lowcurrent PLCs) to 4 A.

Plunger types
Plungers for position switches are made of stainless steel andare extremely accurate.With its special surface-finished plunger guide, an extremelyreliable and maintenance-free operation is given.
There are two different types of actuating systems, dependingon the application. For standard applications, the plunger is fittedwith a telescopic device. With this system, the plunger can bedepressed to the reference surface without damaging theswitching element.
Instead of this telescopic plunger, position switches which havea safety function (with safety switching element) have a rigidplunger which ensures a direct opening action contact inaccordance with IEC 60947-5-1. This means that in the event ofmechanical failure of the switching element - e.g. failure of acontact spring or contact weld resulting from an overload, - thecontact point will be reliably opened.

Plunger travel
The pictures show the various positions of plunger actuated bya control cam.The precise values for the relevant design are shown in thetechnical data.
Travel ratio plunger-switching cam
All the plunger travel data shown in the technical data refers toaxial actuation. The travel for radial actuation with angledswitching cams is increased and this must be calculated.
Plunger types
Depending on the technical requirements, four different plunger types (chisel, roller, ball and domed plungers) are used.
Chisel plunger Hardened and polish-ground.Repeat accuracy to ± 0.002 mm.Max. approach speed of 10 m/min.With its high repeat accuracy, the domedplunger is ideal for setting reference pointsfor moderate approach speeds.
Roller plunger Hardened roller.Repeat accuracy to ± 0.01 mm.Max. approach speed of 50 m/min.The roller plunger is suitable for higherapproach speeds. For very high approachspeeds and long travel distances, rollerplungers with a protected ball bearing canbe offered on request.
Ball plunger Hardened ball.Repeat accuracy to ± 0.01 mm.Max. approach speed of 10 m/min.This plunger can be actuated from anumber of different directions.It must not be used in conjunction withsafety switching elements!
Domed plunger Hardened and polish-ground.Repeat accuracy to ± 0.002 mm.Max. approach speed of 10 m/min.This plunger can be actuated from anumber of different directions.For use in conjunction with safety switchingelements!
Extended Robust roller plunger for moderateroller plunger approach speeds.
