Our cylin­der sen­sors with metal hous­ing were cus­tom de­vel­oped for use in tough en­vi­ron­ments.

The mag­netic-field-sen­si­tive sen­sors are es­pe­cially ro­bust as re­gards weld­ing spat­ter and fly­ing sparks, as well as abra­sion. They with­stand high tem­per­a­tures to 105°C with­out prob­lems.

Our abra­sion-re­sis­tant sen­sors with W at­tri­bu­tion can dif­fer­en­ti­ate be­tween the mag­netic fields which can be used for po­si­tion­ing the pis­ton and the par­a­sitic al­ter­nat­ing mag­netic fields which sur­round the con­duc­tive lines for weld­ing. Weld­ing cur­rents to 25 kA can­not in­flu­ence the sen­sor’s func­tion­ing since the ini­tial state of the sen­sor is stored dur­ing weld­ing.

The fea­tures

• Ro­bust metal hous­ing
• Re­sis­tant to tem­per­a­tures of up to 105ºC
• Im­mu­nity to mag­netic weld­ing in types with W at­tri­bu­tion
• Exact po­si­tion recog­ni­tion even at high tem­per­a­tures
• Re­li­able switch­ing process thanks to pre­cise switch­ing points
• Wear free, since con­tact­less and with­out mov­ing parts
• Re­sis­tant to dirt

Bal­luff has de­vel­oped minia­ture cylin­der switches es­pe­cially for short-stroke cylin­ders and mini-grip­pers. Our mini-sen­sors are among the small­est on the mar­ket and have an exact switch­ing point. They thus guar­an­tee the high­est pre­ci­sion even with min­i­mal switch­ing paths.

The fea­tures

• Re­li­able switch­ing process thanks to pre­cise switch­ing points
• Con­tact-free and there­fore wear-free
• Re­sis­tant to dirt
• Firm grip
• Mounts quickly
• Vari­a­tions that con­nect to two sen­sors via only one plug
• For BMF 103 with slid­ing block: With an ac­tive con­nec­tion, only a short groove length is re­quired (also avail­able with one plug for two sen­sors)

The cylin­der walls of pneu­mat­i­cally and hy­drauli­cally dri­ven ac­tu­a­tors and drive units are typ­i­cally pro­vided with grooves. The sen­sors which reg­is­ter the move­ment of the mag­netic pis­tons are mounted here.

Bal­luff of­fers mag­netic-field-sen­si­tive sen­sors for all cur­rent C- and T-grooves as well as adapter el­e­ments that per­mit re­li­able mount­ing of the sen­sors on rods, tubes and other shapes. For ex­am­ple, so­lu­tions for short-stroke cylin­ders in grip­per ap­pli­ca­tions – with a con­fig­u­ra­tion for two sen­sors on one plug. Or our minia­ture cylin­der switches which are among the small­est sen­sors on the mar­ket. They fea­ture an exact switch­ing point and as­sure re­li­able use even in short groove lengths.

The fea­tures

• Con­tact-free and there­fore wear-free
• Re­li­able po­si­tion de­ter­mi­na­tion for all cur­rent cylin­der dri­ves
• A small num­ber of basic types as­sures uni­ver­sal im­ple­men­ta­tion
• Con­fig­u­ra­tions with fixed or ad­justable switch­ing points
• All cur­rent switch­ing out­puts and con­nec­tion types
• Con­fig­u­ra­tion with two sen­sors on one plug

• Prod­uct fam­i­lies with flex­i­ble mount­ing sys­tems and adapters for a variety of mount­ing so­lu­tions

Our cylin­der sen­sors for round cylin­ders are se­curely in­te­grated into dif­fer­ent ap­pli­ca­tions with the ap­pro­pri­ate hose clamp and mount­ing bracket. The well thought-out mount­ing bracket con­cept is suit­able for most types of cylin­der up to 80 mm pis­ton di­am­e­ter. Pis­ton po­si­tion is reg­is­tered con­tact­lessly through the cylin­der wall.

The fea­tures

• Up to 80 mm pis­ton di­am­e­ter
• Re­li­able switch­ing process thanks to pre­cise switch­ing points
• Con­tact-free and there­fore wear-free
• Re­sis­tant to dirt
• Firm grip
• Mounts quickly

Our cylin­der sen­sors for C- and T-grooves with ad­justable mul­ti­ple switch­ing points en­able quick in­te­gra­tion of pneu­matic and hy­draulic cylin­der dri­ves in ma­chine con­trol.

Mag­netic sen­sors with fixed switch­ing points must be man­u­ally placed on the de­sired switch­ing point and mounted in this po­si­tion. With our teach­able sen­sors, it is suf­fi­cient to place the sen­sor in the ap­prox­i­mate place and fix it there. The switch­ing point or switch­ing points are then de­fined with the teach but­ton” on the con­trol panel.

In the sim­plest case, two dif­fer­ent switch­ing points on the same cylin­der can be ad­justed. In the IO-Link ver­sion, it is pos­si­ble to de­fine and scan up to eight switch­ing points within the work area of the sen­sor. Using this, the sen­sors can, for ex­am­ple, rec­og­nize up to eight dif­fer­ent ob­ject sizes in one grip­per. In this man­ner, one sen­sor can re­place mul­ti­ple con­ven­tional sen­sors. This means sig­nif­i­cantly more com­fort for you and greater flex­i­bil­ity and cost sav­ings.

The fea­tures

• Con­tact-free and there­fore wear-free
• In­di­vid­ual in­stal­la­tion of the switch­ing points with­out tools
• Ap­plic­a­ble for cylin­ders and grip­pers with ra­dial or axial mag­netic po­lar­iza­tion
• Re­mote-Teach of up to 8 switch­ing points via IO-Link
• Ad­justable hys­tere­sis for each in­di­vid­ual switch­ing point
• Ex­tremely large, 60 mm travel path
• Uni­ver­sally ap­plic­a­ble bracket for the teach-in mod­ule avail­able
• Sta­tus in­di­ca­tion via mul­ti­ple col­ored LEDs
• Cap­tive switch­ing points even dur­ing power out­age

Our mag­netic cylin­der sen­sors for T-grooves can be mounted di­rectly in the groove and are dis­tin­guished by their par­tic­u­larly firm grip. They mount flush so that they are suit­able for space-crit­i­cal ap­pli­ca­tions.

In ad­di­tion, Bal­luff of­fers ex­tremely short con­fig­u­ra­tions for flex­i­ble use pos­si­bil­i­ties. The sen­sors de­tect pis­ton po­si­tion con­tact­lessly through the cylin­der walls. The sys­tem is adapt­able for cylin­ders and grip­pers as well as with strong and weak mag­nets.

Thanks to the es­pe­cially bright LEDs, they re­li­ably rec­og­nize the switch­ing state of the sen­sor even at a large dis­tance. The cylin­der sen­sors for T-grooves are also avail­able in metal hous­ings for use in very harsh en­vi­ron­ments, for ex­am­ple with weld­ing spat­ter or fly­ing sparks. Or with mag­net-sen­si­tive elec­tron­ics for in­dus­trial en­vi­ron­ments with high weld­ing cur­rents.

The fea­tures

• Re­li­able switch­ing process thanks to pre­cise switch­ing points
• Con­tact-free and there­fore wear-free
• Re­sis­tant to dirt

Our tem­per­a­ture-re­sis­tant sen­sors are de­signed for tem­per­a­tures to 160 °C. The hous­ing as well as the cable con­struc­tion are op­ti­mized for higher tem­per­a­tures,with the elec­tron­ics com­pletely in­te­grated. Some vari­a­tions are avail­able as high pres­sure sen­sors which makes use even more flex­i­ble, there­fore you re­duce main­te­nance costs, in­crease your process qual­ity and op­ti­mize your sys­tem avail­abil­ity.

The fea­tures

• No sens­ing dis­tance drift under tem­per­a­ture
• Tem­per­a­ture ranges up to 160 °C avail­able

Our cylin­der sen­sors for tie-rod cylin­ders can be re­li­ably in­te­grated into a va­ri­ety of ap­pli­ca­tions. This is en­sured by the mount­ing: The sen­sors are com­pletely tra­di­tion­ally mounted with mount­ing brack­ets on cylin­ders with tie rods and DUO rails. The well thought-out mount­ing bracket con­cept is suit­able for most cur­rent types of cylin­der with any pis­ton di­am­e­ter. Pis­ton po­si­tion is reg­is­tered con­tact­lessly through the cylin­der wall.

The fea­tures

• Tie rod di­am­e­ter up to 17 mm
• Re­li­able switch­ing process thanks to pre­cise switch­ing points
• Con­tact-free and there­fore wear-free
• Re­sis­tant to dirt
• Firm grip
• Mounts quickly

Com­pact mag­netic Global cylin­dri­cal sen­sors from Bal­luff are ac­cu­rately matched to the dif­fer­ent cylin­der groove forms and there­fore pro­vide an op­ti­mum hold. They can not only be in­stalled flush in the re­spec­tive slot, but also fit in com­pletely thanks to their per­fect fit.

The fea­tures

• Com­pat­i­ble with nearly all com­mon types of nut, such as C- or T-nuts
• Large choice of cable and con­nec­tor types
• V-Twin® – one plug for two sen­sors

Our mag­netic cylin­der sen­sors for trape­zoidal grooves can be eas­ily mounted on the cir­cle with hold­ing brack­ets and adapters. The well thought-out mount­ing bracket con­cept is suit­able for most types of cylin­der with trape­zoidal groove or trape­zoidal guide. In ad­di­tion, we offer sen­sor vari­ants which fit di­rectly on a cylin­der with a 60° and 90° trape­zoidal groove with­out a mount­ing bracket. The sen­sors de­tect pis­ton po­si­tion con­tact­lessly through the cylin­der walls. The sys­tem is adapt­able for cylin­ders and grip­pers as well as with strong and weak mag­nets.

The fea­tures

• Re­li­able switch­ing be­hav­ior
• Pre­cise switch­ing point
• Con­tact-free and there­fore wear-free
