OMNI-BEAM ™
Featuring Banner's Exclusive D.A.T.A.™ (patented*) Complete Self-diagnostic System
Polarized retroreflective mode sensor head with low switching
hysteresis design; ideal for many low-contrast sensing applications,
especially clear object detection
D.A.T.A.™ (Display and Trouble Alert) complete self-diagnostics
system displays an early warning of specific sensing problems
before a failure occurs, preventing expensive down-time
D.A.T.A. system provides a 10-element LED signal strength indicator
for display of relative received signal level and optical contrast
In the event of a sensing problem, the D.A.T.A. system sends a
warning signal to the system controller or to an audible alarm
Modular design with interchangeable power blocks for either AC or
DC operation and provision for optional timing logic modules
DC operation features exclusive Banner Bi-Modal™ output for either sinking or sourcing interface require-
ments
The OMNI-BEAM model OSBLVAGC is a polarized retroreflective
mode sensor head module designed especially for sensing of clear
objects. It includes Banner's patented* D.A.T.A.™ system (see
below), a complete early warning diagnostic system that enables
precise monitoring of light signal strength and also alerts you to
potential sensing problems before they occur.
The OSBLVAGC sensor head module is built with a low switching
hysteresis design. This, in combination with the unequalled signal
strength and optical contrast indicating capabilities of the D.A.T.A.
display sysem, makes the OSBLVAGC an outstanding, easy-to-use
performer in many low contrast sensing applications. A discussion of
low-hysteresis sensing and instructions for sensor setup are given on
pages 3 and 4.
The special lens of the OSBLVAGC polarizes the emitted light and
filters out unwanted reflections. A multi-turn GAIN control enables
the precise sensitivity adjustment needed in low-contrast applications.
The Banner model OSBLVAGC must be paired with a standard
OMNI-BEAM ac or dc power block module, which provides operat-
ing voltages to the sensor head and contains the sensor output switch-
The ten-element LED array also serves as a signal strength indicator that
permits optimum alignment and continuous monitoring of signal strength
and sensing contrast.
Operating status is fully dis-
played by separate LED
indicators for "object
sensed" and "output ener-
gized" conditions.
All indicators are viewed
through a gasketed trans-
parent LEXAN
® top cover.
This cover is easily re-
moved for access to the
multi-turn GAIN control,
and to timing adjustments
(when using optional tim-
ing logic module).
The OMNI-BEAM model OSBLVAGC Sensor Block includes Banner's
exclusive, patented D.A.T.A.™ light system. D.A.T.A. is the first and
only complete early warning self-diagnostic system. A multiple-element
LED display is used to warn of an impending sensing problem due to any
of the following causes:
Severe condensation or moisture
High temperature
Low supply voltage
Output overload (dc operation)
Gain too high
Low gain
Low optical contrast (light-to-dark differential)
When one or more of these sensing parameters goes beyond its predefined
limits, the D.A.T.A. lights identify the cause of the problem by flashing a
specific LED or a combination of LEDs in the array. Additionally, a
separate alarm output changes state to signal the system controller or
personnel that sensing conditions have become marginal.

ing device(s) to control the load. Compatible power blocks are listed
on page 5.
DC power block modules operate from 10-30V dc and include
Banner's exclusive Bi-Modal™ solid-state output circuitry which
includes both sinking and sourcing switching capabilities, depending
upon the hookup configuration used. Each output is capable of 100
mA continuous load.
AC power blocks modules are available for either 105-130V or 210-
250V ac. The output device is a solid-state relay capable of 500 mA
continuous load.
Standard power blocks include an alarm output that signals the
existence of sensing problems detected by the D.A.T.A. system.
The OSBLVAGC may also be used with optional timing logic
modules (see page 5), which plug easily into the bottom of the sensor
head and may be added to the sensor at any time.
The OSBLVAGC should be used only with high-quality corner cube
retroreflectors such as Banner models BRT-.6, BRT-1, BRT-1.5, and
BRT-3 (see excess gain curve and discussion, page 4). A selection of
sensor mounting brackets is available (see page 6).
