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

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

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

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
