2 MULT-BAM ensors 783 LR4887 Banner MULT-BAM sensors are compact modular self contained photoelectric switches. ach MULT-BAM 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. t 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. t contains a power supply for the MULT-BAM 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. t provides the desired timing logic function (if any), plus the ability to program the output for either light- or dark-operate. The emitters of MULT-BAM emitter-receiver pairs do not require a logic module. mitter scanner blocks are supplied with a bladepin to interconnect the scanner block and power block. This modular design, with field-replaceable power block and logic module, permits over 5, sensor configurations, resulting in exactly the right sensor for any photoelectric application. There are two families of MULT-BAM sensors: 3- and 4-wire, and 2-wire. Three- and four-wire MULT-BAMs 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 MULT-BAMs are used in ac-powered applications where simplicity and convenience of wiring are important. They are physically and electrically interchangeable with heavy-duty limit switches. The circuitry of all MULT-BAM components is encapsulated within rugged, corrosion-resistant VALO housings, which meet or exceed MA, 3, 2, and 3 ratings. Most MULT- BAM scanner blocks include Banner's patented Alignment ndicating Device (AD ) which lights a top-mounted LD when the sensor sees its own modulated light source and pulses the LD at a rate proportional to the received light signal. Most MULT-BAM sensor assemblies are UL listed and certified by A (see power block listings). All MULT-BAM components (except power block models 2PBR and 2PBR2) are totally solidstate for unlimited life. omposite Functional chematic, 3- and 4-wire ensors

3 election of MULT-BAM omponents MULT-BAM sensors are made up of three components: scanner block, power block, and logic module. This is true for all MULT- BAMs with the exception of opposed mode emitter units which require only a power block (no logic module). Upper over (lens) (supplied with canner Block) Logic Module canner Block ousing The first decision in the component selection process is to determine which family of MULT-BAM sensors is appropriate for the application: 3- and 4-wire, or 2-wire. ext, 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 MULT-BAM assembly. omponents snap together without interwiring to form a complete photoelectric sensing system that meets your exact requirements while maintaining the simplicity of a self-contained sensor. f you have any questions about selecting MULT-BAM components, please contact your Banner sales engineer or call Banner's Applications Department at (62) during normal business hours.
