MAXI-BEAM®
MAXI-BEAM™ Sensor Heads
Modular Sensors
Banner MAXI-BEAM sensors are highly versatile, self-contained,
modularized photoelectric sensing controls that are ideally suited to
industrial environments. The basic MAXI-BEAM is an ON/OFF
switch consisting of three modules: a sensor head, a power block, and
a wiring base.
The sensor head contains the complete modulated photoelectric amplifier as well as the emitter and receiver optoelements. A unique,
patented, "programming ring" (supplied with each sensor head) enables you to program your choice of "light" or "dark" operate mode,
sensing range, and response time. MAXI-BEAM sensor heads have an
easily-accessible multi-turn SENSITIVITY control for precise adjustment of system gain. Interchangeable sensor heads are rotatable in 90degree increments, and are available in opposed, retroreflective, diffuse, convergent, and fiber optic models. Each sensor head also
includes Banner's exclusive, patented Alignment Indicating Device
(AID™, U.S. patent #4356393), which lights a top-mounted LED
when the sensor "sees" its own modulated light source and pulses at a
rate proportional to the received light signal strength.
The power block provides the interface between the sensor head and
the external circuit. It contains the power supply for the MAXI-BEAM
plus a switching device to interface with the circuit to be controlled.
DC power block versions operate on 10 to 30V dc and have solid-state
sourcing and sinking outputs rated at 250mA each (maximum). AC
models are available for 120V or 240V ac operation, and are offered in
both 2-wire and 3- or 4-wire formats. The plug-in design of the wiring
base enables easy exchange of the entire sensing electronics without
disturbing the field wiring. Status LEDs on the power block module
continuously indicate the state of the output circuit.
Optional logic modules are available which easily convert the basic
ON/OFF MAXI-BEAM into either a one-shot or delay logic function
control. The logic module comes with a programming ring which is
used to select one of several timing ranges for each logic function.
Timing adjustments are made via two 15-turn clutched potentiometers,
accessible from the outside. Once programmed, the logic module may
be rotated in 90-degree increments to allow time adjustment access
from the most convenient location.
All MAXI-BEAM components are encapsulated within rugged, corrosion-resistant VALOX® housings which meet or exceed NEMA 1, 3,
4, 12, and 13 standards. Modules simply snap and bolt together, with
no interwiring necessary. Module interfaces are o-ring and quad-ring
sealed for the ultimate in dirt, dust, and moisture resistance. All
MAXI-BEAM components (except for power block model RPBR) are
totally solid-state for unlimited life. MAXI-BEAM assemblies have
the same mounting configuration as Banner MULTI-BEAM sensors,
and are physically interchangeable with heavy-duty industrial limit
switches.
Most MAXI-BEAM sensors are CSA certified and UL listed. See the
power block information on pages 8 to 13.
WARNING
!
MAXI-BEAM photoelectric
presence sensors do NOT include the self-checking
redundant circuitry necessary to allow their 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.
Only MACHINE-GUARD and PERIMETER-GUARD Systems, and
other systems so designated, are designed to meet OSHA and ANSI
machine safety standards for point-of-operation guarding devices. No
other Banner sensors or controls are designed to meet these standards,
and they must NOT be used as sensing devices for personnel protection.

Selection of MAXI-BEAM Components
The modular design of the MAXI-BEAM allows you to create a sensor
which is tailored to your exact requirements. To order a MAXI-BEAM,
follow these steps:
Exploded view, MAXI-BEAM Sensor
Sensitivity
Control
1) SELECT A SENSOR HEAD (see pages 3-7).
Sensor heads are available for opposed, retroreflective, diffuse, convergent,
and fiberoptic sensing modes.
Rotatable
Sensor Head
2) SELECT A POWER BLOCK (see pages 8-13).
Power blocks are available for low voltage dc with either a solid-state or an
electromechanical relay output. AC power blocks are available in either
2-wire design with solid-state output or 4-wire design with a choice of solidstate or electromechanical relay output.
Programming
Ring
Optional
Logic Module
3) SELECT A WIRING BASE (see page 8, top). Model RWB4 wiring
base is used for all MAXI-BEAM assemblies (purchase separately).
4) SELECT A LOGIC MODULE, if needed (see pages 14-15).
MAXI-BEAMs operate in the ON/OFF mode (i.e. the output follows the
action within the sensing beam) when no logic module is used. The addition
of a programmable logic module can add process timing control as part of
the MAXI-BEAM sensor assembly.

Response:
HP mode: 10ms
Repeatability:
HP mode: 3.3ms
Fixed-field sensor heads have an emitter element and two differently-aimed
receiver elements. This creates a highgain sensing field able to detect objects of low reflectivity, and a sharp
far-limit sensing cutoff of 50mm (2
inches) or 100mm (4 inches) which
ignores backgrounds beyond cutoff.
These sensors are ideal for detecting a
part or surface that is only a fraction of
an inch in front of another surface.
RSBFFs may not be used with 2-wire
power blocks.

Programming the MAXI-BEAM Sensor Head
MAXI-BEAM sensor heads may be programmed for sensor response time (and range) and for
LIGHT/DARK operate. Each sensor head is supplied with a programming ring which attaches
below the the sensor head by a system of pegs. There are four programming notches around the
perimeter of the ring. To program the sensor head, simply find the notch which will line up with
the desired program combination (see diagram, right). NOTE: the programming ring may have
to be turned upside-down in order to line up the notch with the program. If LIGHT OPERATE
is selected, the MAXI-BEAM output will energize on a dark-to-light transition. If DARK
OPERATE is selected, the MAXI BEAM output will energize on a light-to-dark transition. In
the illustration, the MAXI-BEAM is set for high speed (HS) operation in the LIGHT OPERATE
output state. See the information about each individual sensor head for the response time and
range associated with each setting (HP, 2W, HS, SP). NOTE: when programming the RSBE,
RSBSER, or RSBEF emitter, select the mode which is programmed for the receiver. EXCEPTION: if the receiver is programmed for the 2-wire (2W) mode, select high power (HP) on the
emitter.

MAXI-BEAM Power Blocks and Wiring Base
MAXI-BEAM power blocks provide regulated low voltage dc power to the sensor head and
logic module (if one is used), and all power blocks (except emitter-only types) contain an
output switch for interfacing to loads or to control circuitry.
Power blocks plug into the model RWB4 wiring base which has heavy-duty screw
terminals that accept up to #12 gauge wire (no lugs are necessary). The RWB4 wiring base
is necessary for all MAXI-BEAM sensor assemblies (except sensors using the RPBTLM
power block), and must be purchased separately.
RWB4 Wiring Base
Power Block
(order separately)
All power blocks, except the emitter-only types, include status LEDs which continuously
indicate the state of the output circuit and input power. MAXI-BEAM power blocks are
epoxy-encapsulated and rated for -40 to +70 degrees C (except models RPBR and RPBR2).
All MAXI-BEAMs have circuitry to prevent false closure of the output on power-up.

Power block RPBT is the one most often used in low voltage dc applications. There are two
solid state output switches (transistors), each rated at 1/4 amp. The NPN output at terminal #3
of the wiring base sinks current to the negative side of the power supply. The PNP output at
terminal #4 sources current to the load from the positive side of the power supply. Both outputs
may be used simultaneously. Response time of a MAXI-BEAM which uses model RPBT is
the response time which is programmed at the sensor head (plus logic delays, if any). Model
RPBT-1 is the dc power block to use with model RSBE, RSBESR, and RSBEF emitter sensor
heads. The RPBT-1 has no switching elements.

Model RPBR operates the MAXI-BEAM with either ac or dc. It offers an SPST "hard" relay contact
between wiring base terminals #3 & #4, which allows the MAXI-BEAM sensor to directly interface with
loads which draw high current. It also allows series connection ("AND" logic) with multiple dc sensors.
Application caution: power block models RPBR and RPBR2
Power block modules RPBR and RPBR2 use "partial phase firing" power
conversion to enable their wide range of ac input voltage (12 to 250V ac).
AC power is applied to the sensor for only a small portion of each ac halfcycle. The current demand during this period may be as high as 1 to 2
amps per sensor.
The collective current demand of several of these sensors on a common
ac line is significant. If several sensors are wired directly to the ac mains,
it is unlikely that any adverse effects will be noticed. On the other hand,
problems may be noticed if several sensors are connected to a common
circuit that is isolated from the ac mains by a transformer. The collective
peak current demand may rob other components on the same circuit of
enough power to function properly. In the worst case, a transformer with
inadequate reserve current capacity may overheat. Barring a transformer failure, the
sensors themselves will operate normally.
As a general rule, if more than three or four MAXI-BEAM sensors using RPBR or RPBR2
power blocks must be connected to the same transformer-isolated ac circuit, consider the
substitution of power block model RPBAR2 (for 105-130V ac) or model RPBBR2 (for
210-250V ac), which use conventional ac-to-dc power conversion circuitry. These power
blocks connect exactly like model RPBR2, but do not exhibit the peak power demand of a
phase-fired design. Output relay specifications are identical to model RPBR2. Contact
your Banner representatiove or distributor for pricing and availability.
NOTE: Peak power demand is not an issue when the RPBR or RPBR2 are powered from
direct current (12 to 30V dc).

NOTE: ac loads require up to 8.3 milliseconds to turn

Power block models RPBA and RPBB are the most commonly used for ac MAXI-BEAM
operation. As the typical hookup shows, they are intended to switch the same ac voltage as is used
to power the MAXI-BEAM. However, both can switch any ac voltage that is lower than the
supply voltage, as long as both ac circuits share a common neutral. Observe local codes whenever
mixing ac voltages in a common wiring chamber.
These blocks are designed to handle the inrush current of ac inductive loads like motor starters
and solenoids. There is no mimimum load requirement, and they will interface directly to inputs
of all ac programmable logic controllers (PLCs). Special order models RPBAT (120V ac) and
RPBBT (240V ac) are available for interfacing to dc loads of up to 100 milliamps.

Power block models R2PBA and R2PBB both offer the simplicity of wiring which is
associated with 2-wire sensor design. They wire directly in series with an ac load, exactly
like a limit switch. Use of a 2-wire power block requires programming of the sensor head
to the "2W" (2-wire) operating mode. As a result, MAXI-BEAM sensing response time is
fixed at 10 milliseconds for 2-wire operation. There are some hookup considerations which
are unique to 2-wire interfaces. See hookup information on page 12 for details.

Multiple 2-wire MAXI-BEAMs may be wired together in
parallel to a load for "OR" or "NAND" logic functions.
When sensors are wired in parallel, the off-state leakage
current through the load is equal to the sum of the leakage
currents of the individual sensors. Consequently, loads
with high resistance like small relays and electronic circuits may require artificial load resistors.

MAXI-BEAM sensors have a 100 millisecond power-up
delay for protection against false outputs. When 2-wire
MAXI-BEAMs are wired together in parallel, any power
block which has an energized output will rob all other 2wire power blocks of the voltage needed to operate the
sensor. When the energized output drops, there will be a
0.1 second delay before any other MAXI-BEAM can
energize. As a result, the load may momentarily drop out.

2-wire MAXI-BEAM sensors cannot wire in series with
other 2-wire sensors. If series connection of 2-wire AC
sensors is required, consider models within the VALUBEAM or MINI-BEAM sensor families. 4-wire ac power
blocks can wire in series (see RPBA, RPBB).
MAXI-BEAM sensors using power block R2PBA or R2PBB wire in
series with an appropriate load. This combination, in turn, wires directly
across the ac line. A 2-wire sensor may be connected exactly like a
mechanical limit switch.
The MAXI-BEAM remains powered when the load is OFF by a residual
current which flows through the load. This off-state leakage current is
always less than 1.7 milliamps. The effect of this leakage current
depends upon the characteristics of the load. The voltage which appears
across the load in the OFF state is equal to the leakage current of the
sensor multiplied by the resistance of the load:
V (off) = 1.7mA x R(load).
2-wire MAXI-BEAMs with
Series Contacts
2-wire MAXI-BEAM sensors may be wired in
parallel with mechanical switch or relay contacts. The load will energize when either a
contact closes or the sensor output is energized.
When a contact is closed, it shunts the operating
current away from the MAXI-BEAM. As a
result, when all of the contacts open, the
MAXI-BEAMs 0.1 second power-up delay
may cause a momentary drop-out of the load.
When 2-wire MAXI-BEAM sensors are connected in series with mechanical switch or relay
contacts, the sensor will receive power to operate only when all of the contacts are closed. The
false-pulse protection circuit of the MAXIBEAM will cause a 0.1 second delay between
the time that the last contact closes and the time
that the load can energize.

If this resultant OFF state voltage is less than the guaranteed turn-off
voltage of the load, then the interface is direct. If the OFF state voltage
causes the load to stay ON, then an artificial load resistor must be
connected in parallel with the load to lower its effective resistance. Most
loads, including most programmable logic controller (PLC) inputs, will
interface to 2-wire sensors with 1.7mA leakage current, without the need
for an artificial load resistor.
MAXI-BEAM 2-wire sensors operate with
low (1.7mA) off-state leakage current. As a
result, they will interface directly to most
PLCs without the need for an artificial load
resistor. If the off-state voltage (1.7mA x
input resistance of PLC) is higher than the
PLC sensing threshold, install a 10KΩ to
15KΩ, 5 watt resistor for each 2-wire sensor.
The resistor connects between the input terminal and ac neutral.

MAXI-BEAM Power Blocks
Model RPBTLM Low Profile DC Power Block
Model RPBTLM is a miniature dc power block for MAXI-BEAM sensors. It
may be used with any of the MAXI-BEAM sensor head models. The RPBTLM
is supplied with stainless steel hardware used for assembly of the MAXI-BEAM
components. Components simply bolt together, with no interwiring necessary.
The screws supplied are extra-long, and serve as a means to mount the complete
MAXI-BEAM sensor assembly to an object or surface.
The RPBTLM may be attached to its sensor head at any of four 90-degree
increments to allow the best cable exit direction (front, rear, or either side). A
logic module may be added and can be independently rotated (in the same
manner) for easiest access to the timing adjustments.
Outputs are in the bi-polar configuration: one current-sinking (NPN) plus one
current-sourcing (PNP). This design permits direct interfacing of the MAXIBEAM sensor to almost any type of dc logic input. Each output is rated for 150
mA. Either output may be used alone, or both may be used simultaneously. The
outputs may be configured for either normally open or normally closed operation
via the sensor head (or logic module) programming ring. The RPBTLM includes
an LED indicator to show the output status.
RPBTLM Dimensions
The RPBTLM is completely solid-state and epoxy-encapsulated. It is gasketed
to other MAXI-BEAM components by a quad-ring seal. See pages 3,7, and 1415 for information on the assembly and programming of MAXI-BEAM sensors.

are two logic modules available. Model RLM5 is programmable for ON-DELAY, OFFDELAY, and ON/OFF DELAY timing logic. Model RLM8 offers both ONE-SHOT and
DELAYED ONE-SHOT functions. A programming ring is supplied with each logic
module. Programming of the logic function, timing range, and output state is similar to
sensor head programming.
Both logic modules feature 15-turn, clutched potentiometers for accurate timing adjustments. Once programmed, the logic module may be rotated in 90-degree increments to
position the timing adjustments for easiest access. Logic modules are housed in the same
tough molded VALOX® which is used for the other MAXI-BEAM components. The logic
module and its programming ring simply slip between the MAXI-BEAM sensor head and
power block (see photograph, page 3). The assembly is bolted together with no interwiring
necessary. The component interfaces are quad-ring sealed.
MAXI-BEAM Logic Module Specifications
SUPPLY VOLTAGE: input power is supplied by the power block
(see pages 8-13).
RESPONSE TIME:

PROGRAM CHOICES:
1) Timing Logic Function:
a) ON-delay b) OFF-delay c) ON/OFF-delay
2) Timing Adjustment Range (see options below)
3) Output State:
a) normally open b) normally closed
TO PROGRAM LOGIC MODULE:
1) Find the programming notch which lines up with the program choice. NOTE:
the programming ring may have to be turned upside-down in order to find a notch
that lines up with the desired program.
2) Press the programming ring and logic module together. They will be held
together temporarily by their interlocking pegs.
3) Orient the logic module for easiest access to the timing adjustments, and
assemble between the programming ring of the sensor head and the power block
(see exploded view on page 3). Bolt all parts together with the long bolts that are
supplied with the logic module.
4) Apply power to the MAXI-BEAM and adjust timing, using a small flat-blade
screwdriver. Timing potentiometers are located behind the nylon o-ring gasketed cover screws.
