banner multi-beam ? sensors are compact modular self con- tained photoelectric switches. each multi-beam consists of three components: scanner block, power block, and logic module. the scanner block contains the complete modulated photoelectric amplifier as well as the emitter and receiver optoelements. it also contains the sensing optics and the housing for the other two modules. the power block provides the interface between the scanner block and the external circuit. it contains a power supply for the multi-beam plus a switching device to interface the circuit to be controlled. the logic module interconnects the power block and scanner block both electrically and mechanically. it provides the desired timing logic function (if any), plus the ability to program the output for either light- or dark-operate. the emitters of multi-beam emitter-receiver pairs do not require a logic module. emitter scanner blocks are supplied with a blade- pin to interconnect the scanner block and power block. this modular design, with field-replaceable power block and logic module, permits over 5,000 sensor configurations, resulting in exactly the right sensor for any photoelectric application. there are two families of multi-beam sensors: 3- and 4-wire, and 2-wire. three- and four-wire multi-beams offer the greatest selection of sensor configurations. they permit either ac or dc operation and offer the fastest response times and the greatest sensing ranges. two-wire multi-beams are used in ac-powered applications where simplicity and convenience of wiring are important. they are physically and electrically inter- changeable with heavy-duty limit switches. the circuitry of all multi-beam components is encapsulated within rugged, corrosion-resistant valox ? housings, which meet or exceed nema 1, 3, 12, and 13 ratings. most multi- beam scanner blocks include banner's patented alignment indicating device (aid?) which lights a top-mounted led when the sensor sees its own modulated light source and pulses the led at a rate proportional to the received light signal. most multi-beam sensor assemblies are ul listed and certified by csa (see power block listings). all multi-beam components (except power block models 2pbr and 2pbr2) are totally solid- state for unlimited life. composite functional schematic, 3- and 4-wire sensors ? multi-beam sensors lr41887 e71083
multi-beam sensors are made up of three components: scanner block, power block, and logic module. this is true for all multi- beams with the exception of opposed mode emitter units which require only a power block (no logic module). the first decision in the component selection process is to determine which family of multi-beam sensors is appropriate for the applica- tion: 3- and 4-wire, or 2-wire. next, decide which scanner block (within the selected family) is best for the application. the guidelines in the catalog introduction will help you to determine the best sensing mode. then narrow the choice by comparing the specifications listed in the following charts and on the pages referenced in the charts. finally, choose a power block and logic module to complete the multi-beam assembly. components snap together without inter- wiring to form a complete photoelectric sensing system that meets your exact requirements while maintaining the simplicity of a self-contained sensor. if you have any questions about selecting multi-beam components, please contact your banner sales engineer or call banner's applications department at (612) 544-3164 during normal business hours. scanner blocks model sensing mode range response page sbe & sbr1 opposed: high speed 150 feet 1 millisecond p. 7 sbed & sbrd1 opposed: high speed, narrow beam 10 feet 1 millisecond p. 7 sbex & sbrx1 opposed: high power, long range 700 feet 10 milliseconds p. 7 sbev & sbrx1 opposed: visible beam 100 feet 10 milliseconds p. 7 sbexd & sbrxd1 opposed: high power, wide beam angle 30 feet 10 milliseconds p. 7 sblv1 retroreflective: high speed, visible beam 30 feet 1 millisecond p. 8 sblvag1 retroreflective: polarized beam (anti-glare) 15 feet 1 millisecond p. 8 sbl1 retroreflective: high speed, infrared beam 30 feet 1 millisecond p. 8 sblx1 retroreflective: high power, long range 100 feet 10 milliseconds p. 8 sbd1 diffuse (proximity): high speed 12 inches 1 millisecond p. 9 sbdl1 diffuse (proximity): medium range 24 inches 1 millisecond p. 9 sbdx1 diffuse (proximity): high power, long range 6 feet 10 milliseconds p. 9 sbdx1md diffuse (proximity): wide beam angle 24 inches 10 milliseconds p. 9 sbcv1 convergent beam: high speed, visible red 1.5-inch focus 1 millisecond p. 10 sbcvg1 convergent beam: high speed, visible green 1.5-inch focus 1 millisecond p. 10 sbc1 convergent beam: high speed, infrared 1.5-inch focus 1 millisecond p. 10 sbc1-4 convergent beam: high speed, infrared 4-inch focus 1 millisecond p. 10 sbc1-6 convergent beam: high speed, infrared 6-inch focus 1 millisecond p. 10 sbcx1 convergent beam: high power, infrared 1.5-inch focus 10 milliseconds p. 10 sbcx1-4 convergent beam: high power, infrared 4-inch focus 10 milliseconds p. 10 sbcx1-6 convergent beam: high power, infrared 6-inch focus 10 milliseconds p. 10 sbef & sbrf1 opposed fiber optic (glass fibers): high speed see specs 1 millisecond p. 11 sbexf & sbrxf1 opposed fiber optic (glass fibers): high power see specs 10 milliseconds p. 11 sbfx1 fiber optic (glass fibers): high power, infrared see specs 10 milliseconds p. 11 SBF1 fiber optic (glass fibers): high speed, infrared see specs 1 millisecond p. 12 SBF1mhs fiber optic (glass fibers): very high speed see specs 0.3 millisecond p. 12 sbfv1 fiber optic (glass fibers): visible red see specs 1 millisecond p. 13 sbfvg1 fiber optic (glass fibers): visible green see specs 1 millisecond p. 13 sbar1 ambient light receiver see specs 10 milliseconds p. 14 sbar1gh ambient light receiver: high gain see specs 10 milliseconds p. 14 sbar1ghf ambient light receiver: for glass fiber optics see specs 10 milliseconds p. 14 3- and 4-wire systems (pages 6 through 23) upper cover (lens) (supplied with scanner block) lower cover (supplied with scanner block) logic timing adjustment light/dark operate select power block wiring terminals scanner block housing logic module selection of multi-beam components
multi-beam 3- & 4-wire scanner blocks description multi-beam 3- & 4-wire scanner blocks offer a complete comple- ment of sensing modes. there are 3 or more models for each sensing mode, resulting in a choice of exactly the right sensor for any applica- tion. the high power models (10 millisecond response time) offer greater optical sensing power than any other industrial sensors. specifications supply voltage: input power and output connections are made via a 3- or 4-wire power block (see pages 15 to 20). response time: 1 millisecond on and off, except high gain models with "x" suffix and ambient light receivers which are 10 milliseconds on and off. repeatability of response: see individual sensor specs. sensitivity adjustment: easily accessible, located on top of scanner block beneath o-ring gasketed screw cover. 15-turn clutched control (rotate clockwise to increase gain). alignment indicator: red led on top of scanner block. banner's exclusive, patented alignment indicating device (aid?) circuit lights the led whenever the sensor detects its own modulated light source, and pulses the led at a rate proportional to the received light level. construction: reinforced valox ? housing with components totally encapsulated. stainless steel hardware. meets nema standards 1, 3, 12, and 13. operating temperature range: -40 to +70 degrees c (-40 to +158 degrees f). valox ? is a registered trademark of general electric company. functional schematic, 3- and 4-wire scanner block dimensions, 3- and 4-wire scanner block
