Advantages:– Sensing range
adjustable 0...40 mm– Low switching point
shift, e.g. for differentcolors or surfaceproperties
– Background fade-outallows detection ofobjects in front of areflective background
– Small parts detectiondown to 0.05 mmusing focusing plano-convex lens witha working range ofapprox. 0...13 mm
Housing material:PA 6Plano-convex lens:Glass
Plano-convex lensfor all BOS 18 diffuse sensorsfor background suppression
and small parts detection
BOS 18-PK-1
Lensfor BKT and BLT for
extending range
BKT M-PK-1
Using thesupplementary lensincreases the rangeof the BKT from 9 mmto 18 mm.This corresponds to aworking range of15...30 mm when usingwith the BLT.
Polarizing filters areused for reliably sen-sing highly reflectiveobjects. They preventfaulty switching.Reflecting or shinyparts will not causefaulty switching. Thepolarizing filtersguarantee that onlythe light reflectedback by the reflectoris detected.They reduce thesensing range by 50%.

Neutral density filterfor BOS 18
BOS 18-NF-_*
The protective end cap ismade with tempered glassand can be used with allM12 photoelectric switches.These caps are usedto protect the optics frommechanical or thermaldamage. Sparks from weldingwill not damage the hardenedglass lens.
Cover nutfor BOS 18
BOS 18-SM-1
The protective cap can beused in combination with allBOS 18M and BOS 18Ksensors. It protects the opticsfrom the effects of weldingsplatter, for example.For increased protection theBOS 18-SM-2 is made ofmetal, providing even betterprotection for the sensoroptics. The heat protectingglass closes off flush with thefront surface of the cover nut.This means no dust depositscan form which wouldotherwise result in a loss ofrange. A ring between thesensor and protective glassmakes sure the system issealed.

BOS 18-SM-2
Neutral density filtersweaken the infalling light,without changing its spectralcharacteristics.The neutral filter is made ofglass with a vacuum coatedmaterial layer. This is hard,non-peeling and resistant toaging.Clean the filter using standardcommercial optical cleaners.

Rotatable heads,suitable combinations
All BOS 18 photoelectricsensors can be equippedwith a 90° rotatable head.The table shows theappropriate rotatable headfor each switch type andindicates the correspondingreduction factor (RF) to applyto the range.In the case of a through-beam sensor both the emitterand receiver can be fittedwith a 90° rotatable head.Each rotatable head reducesthe range by approx. 15 % to30 %.
