Banner MULTI-BEAM
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
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.
