Balluff Safety

Balluff Safety

Safety with Balluff quality

Automation requires safety. Safety is based on reliability. Balluff quality guarantees ultra-reliable solutions. Therefore, the Balluff safety concept also consists of products and solutions that fulfill their tasks over the course of years with the same reliability and precision. This includes a continually increasing number of products and components that contribute to minimizing the danger for humans and production plants. These components can easily be integrated into your system controller.

Unique: Safety over IO-Link

To increase the efficiency of safety concepts and integrate them in the system control, we have developed a safe I/O module: the Balluff Safety Hub, the first integrated safety solution via IO-Link! Safety over IO-Link is easy to integrate, responds quickly and can replace the control cabinet.

Safety over IO-Link links automation and safety technology. IO-Link handles communication down to the last meter and provides both sensor/actuator details as well as secure information. State-of-the-art, with the usual Balluff quality and all from a single source.

Freedom to change your system down to the last minute

By the scaling of topology and safety components, you can easily and quickly adapt your application to changing requirements at any time. Exceptionally flexible down to the last minute.

Safe signal acquisition and communication

The Safety Hub links au­toma­tion and safety tech­nol­ogy for the first time via IO-Link. This new I/O mod­ule is merely linked to the IO-Link Mas­ter. Be­cause the sys­tem is open to­ward the sys­tem level, you can con­nect nearly any safety de­vice.


By con­nect­ing the au­toma­tion and safety tech­nol­ogy, ma­chine pro­tec­tion in one sys­tem is ac­com­plished. This is be­cause IO-Link sup­plies both sen­sor/ac­tu­a­tor de­tails and se­cure in­for­ma­tion. With Safety over IO-Link, you use the best of both worlds. And the in­te­gra­tion of safety tech­nol­ogy be­comes eas­ier than ever be­fore.

The pa­ra­me­ter­i­za­tion is done cen­trally via the con­troller. Safety-re­lated in­for­ma­tion is sent di­rectly through the mas­ter to the con­troller. Using Profisafe via Profinet guar­an­tees se­cure com­mu­ni­ca­tion with the con­troller.

The fea­tures

  • In­fra­struc­ture for au­toma­tion and safety tech­nol­ogy up to PLe / SIL3 via IO-Link
  • Low main­te­nance costs in case of ser­vice thanks to com­pre­hen­sive di­ag­nos­tics and easy de­vice re­place­ment
  • Lower costs by using uni­form M12 sin­gle-ended cord­sets
  • Re­duc­tion of the re­quired IP ad­dresses
  • Stan­dard­ized wiring con­cept, re­li­able guard lock­ing de­vices can be con­nected di­rectly
  • Nearly any safety de­vice can be con­nected

Photoelectric danger zone protection for detecting people

Safety light curtains

BLG 4A safety light cur­tains from Bal­luff are pho­to­elec­tric, elec­trosen­si­tive pro­tec­tive equip­ment. They de­tect fin­gers, hands and other body parts and are used in work areas where ma­chines pre­sent po­ten­tial haz­ards. They stop haz­ardous move­ments in these areas.

The fea­tures

  • Bet­ter use of space by sav­ing on pro­tec­tive fence de­signs
  • Fast in­ter­ac­tion be­tween human and ma­chine
  • High level of ma­nip­u­la­tion pro­tec­tion
  • For de­tect­ing fin­gers, hands and other body parts
  • Safety pa­ra­me­ters: PLe / SIL3
  • De­fined safety zone with pro­tec­tive in­frared field
  • Haz­ardous move­ments are stopped re­li­ably

Robust and reliable locking and guard locking devices

Safety switches

BID F101 safety switches from Bal­luff with a sep­a­rate ac­tu­a­tor pro­vide pro­tec­tion for per­sons and ma­chines. To­gether with a ma­chine con­trol sys­tem and a pro­tec­tive bar­rier, they safe­guard ac­cess to the haz­ardous areas.

You can use our safety switches with­out guard lock­ing, with me­chan­i­cal guard lock­ing or with elec­tri­cal guard lock­ing – com­pletely ac­cord­ing to your re­quire­ments.

The fea­tures

  • Sturdy metal hous­ing with sta­tus dis­play
  • Ro­tat­able ac­tu­at­ing head (90° in­cre­ments) with two in­lets
  • Plug­gable M12 con­nec­tor (5 or 8-pin)
  • Guard lock­ing de­vice avail­able with ei­ther open cir­cuit prin­ci­ple or bias cur­rent prin­ci­ple
  • High hold­ing forces of up to 2500 N
  • Op­tion of switch with or with­out a me­chan­i­cal lock or an elec­tric lock

Emergency stop device in compact housing for easy installation on various machines and systems

The emer­gency stop func­tion must be avail­able at all times for an au­to­mated sys­tem. As a sup­ple­men­tary pro­tec­tive mea­sure, the emer­gency stop de­vice ini­ti­ates an im­me­di­ate stop com­mand when­ever nec­es­sary. There­fore, it can be used for per­sonal pro­tec­tion func­tions. The de­vice must be vis­i­bly and eas­ily ac­ces­si­ble at any time to per­mit a stop­page in the event of an emer­gency.

The fea­tures

  • Re­li­able dis­con­nec­tion of the power sup­ply
  • Pos­i­tive open­ing op­er­a­tion in ac­cor­dance with IEC 60947-5-1
  • Plug­gable con­nec­tion with M12 (5-pin)
  • Turn-to-re­lease mush­room push­but­ton
  • High de­gree of pro­tec­tion against dust and water
  • Com­pact hous­ing, easy in­stal­la­tion

Rugged and wear-free

Non-contact safety sensors

Non-con­tact safety sen­sors are ex­cel­lently suited for mon­i­tor­ing pro­tec­tive doors/cov­ers or for re­li­ably de­tect­ing po­si­tions – es­pe­cially in en­vi­ron­ments in which con­t­a­m­i­na­tion or dust can be ex­pected.

The large op­er­at­ing range and the non-con­tact prin­ci­ple make these sen­sors in­sen­si­tive to me­chan­i­cal play, for ex­am­ple when doors set­tle or are guided in­ac­cu­rately. The small size also pro­vides you with more flex­i­bil­ity, al­low­ing you to eas­ily in­te­grate the sen­sors.

Fea­tures

  • Re­sis­tant to dirt
  • In­sen­si­tive to me­chan­i­cal play
  • Easy to in­te­grate with small form fac­tors
  • Nearly ma­nip­u­la­tion-re­sis­tant thanks to high cod­ing lev­els
  • Flex­i­ble use for ap­pli­ca­tions up to PLe or SIL 3
