MixedAssemblies

Accessories,Replacement Parts

Rotary cam switches areused for controlling,automating, monitoring andcounting work and cyclesequences based on givenmovements of a machine.

Applications

Balluff rotary cam switchesare used successfully onpresses, stampingmachines, forging presses,sheet metal formingmachines, weldingmachinery, machine tools,packaging machines,assembly machinery, transferlines, transport equipment,lifts, elevators, constructionmachinery, miningequipment, steelworks andin the automobile industry.

Mechanical and InductiveRotary Cam Switches

Features,Applications

Their proven design principleand large number ofpossible switchingoperations as well asconsistent inspection ensurelasting quality and reliability.

The system for translatingmachine programs

Two independently rotatingeccentric cam rings oneach switch position enablestepless setting of pulseduration (on- and off-point)and pulse location (0° to360°).The machine program set tothese parameters runsautomatically. A mechanicalor inductive switch elementpasses electrical controlcommands to the machinecontroller.

Reliable switching underextreme conditions

Balluff rotary cam switcheshave for decades proventhemselves under the mostdifficult conditions. Theyensure trouble-free functionunder conditions of vibration,shock, rapid temperaturefluctuations and heavypresence of chips. Inductiverotary cam switches alsofeature high electromagneticcompatibility.

Safety of man andmachine

For safety functions such asE-Stop or end-of-travelrestriction, Balluff designsspecial safety rotary camswitches to DIN EN 60204-1/VDE 0113, which offer thehighest level of safety.DIN EN 60204-1/VDE 0113..

Standard andapplication-specific rotarycam switches

In addition to standardapplications, Balluff offersspecial rotary cam switcheswith features such as shaftbreak security as part ofthe safety regulations of theGerman Iron andMetalworkers Association.Included in the scope ofdelivery are also specialversions with additionalsecuring of the cam rings. Avariety of accessories suchas couplings and gears aswell as additional equipmentfor special applicationsround out this versatile line.

Mechanical and InductiveRotary Cam Switches

Features,Applications

Mechanical rotary camswitches

Rotary cam switches withmechanical switch elementsare used for rotary speedsup to 300/min.The following torques areneeded to turn the rotarycam switch shaft with evenactuation of all plungers.

3-position BSW 0.5 Nm6-position BSW 1.0 Nm9-position BSW 1.5 Nm

12-position BSW 2.0 Nm20-position BSW 3.5 Nm

If multiple rotary camswitches are coupledtogether, the torques for theindividual rotary camswitches add up accordingly.When the rotation speedis changed using gearing,the torque changes also inrelation to the step-up orstep-down.

Drive type

The rotary cam switches can be driven from either the rightor left side by a standard shaft end (40 or 20 mm long,∅ 20 mm) with fit-in key. Each shaft end has an M10 centerthread 9 mm deep.

MechanicalRotary Cam Switches Construction

Construction

The shaft, cam ring set andplunger which actuates themechanical switch elementsare contained in a ruggedhousing.The housing is divided into alower section and cover,which are joined by hinges.M25×1.5 cable fittings arelocated on three sides of thelower section for electricalinstallation.A transparent shield protectsthe free shaft end oppositethe drive side from touchingand allows you to view thescaling ring with etchedmarkings.

Balluff rotary cam switchescan be ordered with 3, 6, 9,12 or 20 switch positions.Mounting holes for flange-mounting couplings andgear units (see Accessories)are located on both bearingflanges of the rotary camswitch).

A cam ring set for eachswitch position is located onthe shaft for actuating theindividual switch elements.

The shaft runs inmaintenance-free bearings.A cam ring set consists of:– a support ring with scale– two independently

adjustable cam rings withadjusting rings

– a compression disc withscale.

This construction enablesstepless adjustment of theswitching points for eachindividual switch positionbetween 0° and 360°without having to loosen ortighten a nut or screw.

The switching point ismarked by a line on eachcam ring.The support ring andcompression disc attachedto the shaft have degreesmarked in oppositedirections for steplesssetting of the pulse lengthand position.The scale ring, which is alsoreads in both directions,allows the respectiveposition of the shaft to beread off.

InductiveRotary Cam Switches Construction

www.balluff.com

Construction of theinductive rotary camswitch standard series

These rotary cam switchesuse the same housing asthe mechanical versions, butdifferent cam ring sets.The switching function ishandled by an inductiveswitch element whose activesurface is dampedcontactlessly by the targetdiscs (cam ring sets).Two independently rotatableeccentric cam rings(180°), with exact edges forprecisely defining theswitching point, are used todetermine the pulse lengthand pulse position.

Principle of operation

When the cam rings dampthe switch element, energy isremoved from the oscillator,and the oscillator voltagedrops. This changes thestate of the output signal inithe switch element.The switch elements aresuitable for direct logiccontrol.

Construction ofinductive rotary camswitches BSW 816-207

In contrast to the standardseries, here the shaft is fittedwith foil carrier discs insteadof cam rings.The two-part foil carrier discis made of plastic with aguide scale from 0° to 360°with a clamp for holding thedamping section.

Aluminum foils are (withpolyester or aluminumcoating) are used to dampthe individual inductiveswitch elements and aresteplessly adjustable on thefoil carrier disc and canbe clamped at any angle.Depending on theapplication each switchposition can also be fittedwith several equally orvariously long aluminum foils(corresponding to pulses).

For these rotary camswitches the same housingsand same switch elementsare used as for the inductiverotary cam switches in thestandard series.

Rotary cam switches withsecurable cam rings X64

These rotary cam switchesare also equipped with asecuring fixture, i.e. eachindividual cam ring isequipped with an adjustingring and security plate. Bysimply bending the securityplate into the slots of theadjusting ring each individualcam ring can be secured atany desired angle position(no drilling out necessary).

Rotary cam switcheswith speed monitor or runchecking

The switch position furthestaway as viewed from thedrive side of the rotary camswitch is equipped, insteadof the usual cam ring set andthe corresponding snapswitch, with a pulse sensor,consisting of a toothed discwith 30 teeth (= 30 pulsesper revolution) and inductiveelectronic switch element(NO and NC).The rotary motion of the camswitch shaft is monitored bythis pulse sensor andevaluated with a speedmonitor.

Rotary cam switches withadditional speed monitoror run checking

This rotary cam switchesincludes an additional pulsesensor, so that no normalswitch positions have to besacrificed. There are twoversions available.– One pulse wheel each is

located to the left or rightof the complete camring package for optionalassembly of thecorresponding proximityswitch

– Proximity switch or slotsensor is attached onthe side opposite the drive(after the last normalswitch position).

When ordering, specify theindividual switch positionsin plain English. Always startfrom the exposed (driven)shaft end.

Mixed assembly switchesare given a specialorder code (see orderingexamples)

When reordering, specify thefull product code includingthe 6-digit code for mixedassembly.
