To order the 4-pin M12/Euro-style QD models, add the suffix QD to the model number. For example, SM31 EQD. To order the 150 mm (6 in) cable with QD, add the suffix QDP to the model number. For example, SM31 EQDP. To order a ms response time model, add the suffix MHS to the model number.

A complete selection of mounting brackets is available. Visit or contact Banner Engineering for information on mounting with line-of-sight positioning of the MINI-BEAM Sensor to its emitter (opposed-mode sensing) or to its target (all othersensing modes). When using a retroreflective Sensor , the target is the retroreflector ( retro target ).

5 For diffuse or convergentsensing modes, the target is the object to be detected. MINI-BEAM DC Voltage - Tel: +1-763-544-3164P/N 69943 Rev. FApply power to the Sensor (and to the emitter, if using the opposed mode). Advance the 15-turn Gain control to maximum(clockwise end of rotation) using a small flat-blade screwdriver. The Gain control is clutched at both ends to avoid damage and will free-wheel when either endpoint is the MINI-BEAM Sensor is receiving its light signal, the red LED Alignment indicator will be ON and flashing at a rate proportionalto the signal strength (faster = more signal). Move the Sensor (or retro target, if applicable) up-down-right-left (including angularrotation) to find the center of the movement zone within which the LED indicator remains ON.

6 Reducing the Gain setting reducesthe size of the movement zone for more precise the alignment motions after each Gain reduction. When optimum alignment is achieved, mount Sensor (s) (and the retrotarget, if applicable) solidly in that position. Increase the Gain to the Sensor by placing the object to be detected in the sensing position, then removing it. The Alignment indicator LED shouldcome ON when the sensing beam is established (Light condition) or be ON when the beam is broken (Dark condition). If theAlignment indicator LED stays ON for both sensing conditions, consider the following tips for each sensing Mode AlignmentObjectEmitterReceiver Flooding occurs when a portion of the sensing beam passesaround the object to be sensed.

7 Burn-through occurs when aportion of the emitter s light energy passes through a thin ortranslucent object, and is sensed by the correct either problem, do one or more of the following toreduce the light energy: Reduce the Gain adjustment on the receiver Add an aperture to one or both lenses ( MINI-BEAM apertures, available from Banner , fit neatly inside thelens assembly) Intentionally misalign the emitter and receiverNote: Light condition: Sensor output isON when there is no object in thebeam Dark condition: Sensor output is ONwhen there is an object in the beamDiffuse Mode AlignmentObjectIf the Alignment LED does not go OFF when the object isremoved from the beam , the Sensor is probably detecting lightreflected from some background object.

8 To remedy thisproblem: Reduce the reflectivity of the background by paintingthe surface(s) flat-black, scuffing any shiny surface, ordrilling a large hole, directly opposite the diffuse Sensor Move the Sensor closer to the object to be detectedand reduce the Gain adjustment. Rule of thumb fordiffuse sensing: The distance to the nearestbackground object should be at least three times thesensing distanceNote: Light condition: Sensor output isON when there is no object in thebeam Dark condition: Sensor output is ONwhen there is an object in the beamMINI- beam DC Voltage Series P/N 69943 Rev. - Tel: +1-763-544-31643 Retroreflective Mode AlignmentRetroTargetA highly reflective object may reflect enough light back to aretroreflective Sensor to allow that object to slip through thebeam, without being detected.

9 This problem is called proxing, and the following methods may be used to correct it: Position the Sensor and retro target so the beam willnot strike a shiny surface perpendicular to the sensorlens Reduce the Gain adjustment Add a polarizing filter (for model SM312LV)Note: Light condition: Sensor output isON when there is no object in thebeam Dark condition: Sensor output is ONwhen there is an object in the beamConvergent Mode AlignmentObjectLow Reflectivity BackgroundThe sensing energy of a convergent mode Sensor isconcentrated at the specified focus point. Convergent modesensors are less sensitive to background reflections, comparedwith diffuse mode sensors. However, if background reflectionsare a problem: Skew the Sensor position at a 10 to 25 angle toeliminate direct reflections from shiny backgroundsurfaces Reduce the reflectivity of the background by paintingthe surface(s) flat-black, scuffing any shiny surface, ordrilling a large hole, directly opposite the Sensor Reduce the Gain adjustmentNote: Light condition: Sensor output isON when there is no object in thebeam Dark condition: Sensor output is ONwhen there is an object in the beamPlastic Fiber InstallationTrimmed fibercontrol endsPlastic fiberemitter portPlastic fiberreceiver portGripperUnlockLockAdapters and fibersSensor Face1.
