® MULTI-BEAM Sensors LR41887 E71083 Banner MULTI-BEAM® sensors are compact modular self contained 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.
Selection of MULTI-BEAM Components MULTI-BEAM sensors are made up of three components: scanner block, power block, and logic module. This is true for all MULTIBEAMs with the exception of opposed mode emitter units which require only a power block (no logic module).

MULTI-BEAM 3- & 4-wire Scanner Blocks Sensing Mode OPPOSED Mode OBJECT Models Excess Gain Beam Pattern SBE/SBR1: this opposed pair has the highest gain available at 1 ms response. SBED/SBRD1: fast response and small effective beam; will detect objects as small as .14 inch in crossection moving at up to 10 feet per second. Best choice for repeatability of position sensing. SBEX/SBRX1: best choice for opposed sensing in extremely dirty environments.
MULTI-BEAM 3- & 4-wire Scanner Blocks Sensing Mode RETROREFLECTIVE Mode OBJECT RETRO TARGET Models Excess Gain Beam Pattern SBLV1: visible beam makes alignment very easy, and is the first choice for most retroreflective applications. Not for use in dirty environments; rather use opposed mode or see SBL1 & SBLX1, below. Do not locate retroreflector closer than 6 inches (15cm) from sensor. SBLVAG1: uses anti-glare filter for immunity to direct reflections from shiny objects.
MULTI-BEAM 3- & 4-wire Scanner Blocks Sensing Mode DIFFUSE Mode OBJECT Models Excess Gain Beam Pattern SBD1: short range diffuse mode sensor with relatively wide field of view. Loses gain rapidly near the end of its range. As a result, its response to background objects is suppressed. However, use caution when applying any diffuse mode sensor if background reflectivity exceeds the reflectivity of the object to be sensed.
MULTI-BEAM 3- & 4-wire Scanner Blocks Sensing Mode CONVERGENT Mode OBJECT Models Beam Pattern Excess Gain SBCV1: .06-inch (1.5mm) dia. visible red spot, for precise positioning, edge-guiding, & small parts detection. Sensor-to-product distance must be consistent. Some products ≥1" tall may be sensed against immediate background like parts on a conveyor. Excellent for high-contrast registration-sensing applications (except red-onwhite).

MULTI-BEAM 3- & 4-wire DC Power Blocks MULTI-BEAM 3- & 4-wire power blocks provide regulated low voltage DC power to the scanner block and logic module, and a solid state infinite-life switch (except in emitter-only scanner blocks). Connections are made to heavy-duty screw terminals which accept up to #14 gauge wire (no lugs are necessary). All power blocks are epoxyencapsulated and rated for -40 to +70 degrees C.

MULTI-BEAM 3- & 4-wire AC Power Blocks Hookup Diagrams for AC Power Blocks (continued) Hookup in Parallel with other MULTI-BEAMs Any number of 3- & 4-wire MULTI-BEAM power block outputs may be connected in parallel to a load. Parallel sensor connection is usually used to yield "OR" logic (i.e., if an event occurs at any sensor, the load is energized).The total off-state leakage current through the load is the sum of the leakage current of the individual power blocks.
MULTI-BEAM 3- & 4-wire Logic Modules The logic module interconnects the power block and scanner block both electrically and mechanically using a unique blade-and-socket connector concept. It also provides the LIGHT/DARK operate function (except in the LM1) and the timing functions, all of which are fully adjustable.
MULTI-BEAM 3- & 4-wire Logic Modules Model and Function Description of Logic LM4-2NR one-shot (non-retriggerable) Pulse Pulse Pulse OUTPUT SIGNAL The LM4-2NR provides a one-shot ("single shot") output pulse each time there is a transition from LIGHT to DARK (jumper installed) or from DARK to LIGHT (jumper removed). The output pulse time range is adjustable from 0.1 to 1 second. The duration of the pulse is independent of the duration of the input signal.

MULTI-BEAM 2-wire Sensors 2-wire MULTI-BEAM The components of the MULTI-BEAM 2-wire family of modular self-contained sensors are physically identical to the 3- & 4-wire components. However, the 2wire components are designed to wire directly in series with an ac load, exactly like a limit switch. This design makes the 2-wire MULTI-BEAM impossible to wire backward.

MULTI-BEAM 2-wire Power Blocks MULTI-BEAM 2-wire power block models 2PBA, 2PBB, and 2PBD contain a low voltage power supply which utilizes a unique circuit to take a very small leakage current through the load and convert it to the dc power required to run the scanner block and logic module. They also contain the solid-state switch that operates the load, and a transient suppression circuit to prevent false operation from high voltage spikes on the incoming line.
MULTI-BEAM 2-wire Power Blocks Hookup Diagrams for 2-wire Power Blocks (except models 2PBR & 2PBR2; see page 27) NOTE: output has maximum load capacity of 3/4 amp; maximum resistive load 15K ohms, minimum inductive load 1.2 watts (10mA) 2-wire MULTI-BEAMs in Parallel Basic Hookup of 2-wire MULTI-BEAM L1 (See Specifications) 2PBA 2PBB 2PBD 1 2 2PBA 2PBB 2PBD 1 2 2-wire MULTI-BEAM sensors have a 100 millisecond power-up delay for protection against false outputs.
MULTI-BEAM 2-wire Logic Modules 2-wire logic modules provide the mechanical and electrical connection between the scanner block and the power block of a 2-wire MULTI-BEAM sensor. In addition, the logic module provides the LIGHT/DARK programming of the output plus delay or pulse timing, if required. 2-wire logic modules are all color-coded black (3- and 4-wire logic modules are red). The timing ranges listed below are standard.
MULTI-BEAM Accessories Upper Covers (Lens Assemblies) An upper cover consists of the optical element for the MULTI-BEAM which is built into a gasketed cover for the upper portion of the scanner block. Upper covers may be ordered as replacement parts or for modifying the optical response of a particular model scanner block. The following upper cover assemblies are standard and stocked. Other special variations may be quoted. Stainless steel hardware is included with each cover.
MULTI-BEAM Accessories Mounting Brackets Model SMB700 (right) is a general-purpose two-axis mounting bracket that is supplied with a cable gland assembly which is used to attach the MULTI-BEAM wiring base to the bracket. The gland assembly is threaded through the bracket and into the conduit entrance at the base of the scanner block. A large lockwasher is supplied to hold the scanner block firmly in place. The bracket is 11-gauge zinc plated steel.
WARNING ! The photoelectric presence sensors described in this catalog do NOT include the self-checking redundant circuitry necessary to allow thier use in personnel safety applications. A sensor failure or malfunction can result in either an energized or a de-energized sensor output condition. Never use these products as sensing devices for personnel protection. Their use as a safety device may create an unsafe condition which could lead to serious injury or death.
