VALU-BEAMs are a family of rugged, self-contained photoelec-
tric sensors designed for especially demanding industrial applica-
tions where economy, performance, and durability are important.
VALU-BEAMs are built in a variety of operating voltages (both dc
and ac) and output types (solid state and electromechanical relay).
SM912 and SM2A912 Series VALU-BEAMs have solid state
outputs and are available in either 10-30V dc-powered or 24-250V
ac-powered models (see specifications, page 4). SMW915,
SMA915, and SMB915 Series VALU-BEAMs have electrome-
chanical relay output and operate from 12-28V ac/dc, 90-130V ac,
or 210 to 250V ac respectively. SMA990 Series VALU-BEAMs
have a built-in 6-digit totalizing counter and operate on 12 to 115V
dc or 10 to 250V ac. A fourth VALU-BEAM line, SMI912 Series
intrinsically safe sensors (low voltage dc sensors having Factory
Mutual approval for use with intrinsic-safe barriers in hazardous
areas) is covered in data sheet P/N 03396 and the Banner catalog.
Powerful, modulated LED light sources give VALU-BEAM sen-
sors greater sensing range than competitive units and a high degree
of immunity to ambient light. All models are totally epoxy-
encapsulated and housed in molded VALOX
® housings for the
ultimate in shock, vibration, moisture, and corrosion resistance.
All VALU-BEAM sensors conform to NEMA standards 1, 2, 3,
3S, 4, 4X, 12, and 13.
VALU-BEAM sensors may be mounted from either the front or the
rear using their two through-mounting holes, or by the outside
threads of their M30x1.5 threaded base (mounting nut supplied),
making them ideal for conveyor and other production line applica-
tions. A versatile 2-axis steel accessory mounting bracket (model
SMB900) simplifies mounting and alignment. Model SMB30SM
swivel-mount bracket offers the ultimate in flexibility and conve-
nience. The bases of standard VALU-BEAMs have a 1/2" NPS
integral internal conduit thread, and are supplied with a 6-foot
PVC-covered cable. Models with a NEMA-4 rated quick-discon-
nect connector (QD models) are available optionally.
All VALU-BEAM sensors have an easily-visible top-mounted red
LED indicator to assist in alignment and system monitoring. On
SMA915, SMB915, SMW915, and SMA990 Series VALU-
BEAMs, this indicator lights whenever the sensor "sees" its
modulated light source. On SM2A912 Series 2-wire sensors, the
LED lights whenever the load is energized. SM912 Series sensors
have Banner's exclusive, patented "AID" system (Alignment Indi-
cating Device, US patent #4356393) which lights the indicator
LED whenever the sensor "sees" its modulated light source, and
also pulses the LED at a rate proportional to the received light signal
strength. This feature greatly simplifies alignment: in most situa-
tions, alignment becomes simply a matter of positioning the sensor
for maximum LED pulse rate.
VALU-BEAMs offer a choice of light or dark operate in the same
sensor. This is done via a rear panel control or, in the relay output
units, by offering both N/O and N/C output relay contacts.

WARNING
VALU-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 safety devices 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.
