Description
Q45X Series sensors are self-contained dc photoelectric devices designed The Q45X is a 10 to 30V dc sensor with impressive
for reliable sensing in industrial environments. A unique design allows optical performance. Output of the basic sensor (i. e.
the user to instantly customize the basic sensor with the addition of one of without a bus card) is bipolar: one sourcing (PNP)
many optional expansion cards.
and one sinking (NPN) solid-state device. Both
outputs have 250 mA capacity, and may be used
simultaneously. Outputs are converted from light
operate (normally open) to dark operate (normally
closed) via a switch located under the hinged top
cover. This basic output configuration provides a
direct interface to a PLC or to any "smart drop" on a
bus system (see page 5).
Expansion cards will be available for conversion of the basic sensor to
nearly any data bus system protocol. Sensors are easily converted to bus-
compatible devices by simply raising the hinged top cover and plugging
the appropriate bus card into the expansion slot. Bus system expansion
cards are currently planned for DeviceNet™, SDS™, Seriplex™, ASI™,
LON™, and others.
With the bus card installed in the Q45X, "smart drop" junction boxes are
not required. Sensor wiring is accomplished using simple "dumb drop"
junction boxes or "T" connectors. If the bus protocol is ever changed, the
Q45X Series sensors on the network can be quickly converted by simply
inserting a different bus card. Sensors are reconfigured without disturbing
mounting or alignment.
StandardQ45Xfeaturesinclude three highly-visible
sensor status indicator LEDs for power, signal, and
output state. ThePOWER LED flashes to indicate an
overload or short circuit of either output. The
SIGNAL LED incorporatesBanner’spatentedAlign-
ment Indicating Device (AID™) circuitry which
pulses the indicator at a rate which is proportional to
the received light signal strength. A slow flash rate
alerts personnel to a marginal signal due to sensor
misalignment or dirt on the lenses.
The expansion slot also allows numerous advanced sensor features to be
addedtothebasicQ45X,includingsensordiagnosticsanddigitalbargraph
displays. In addition, other advanced functions can be developed to meet
specific customer requirements.
Q45X sensors are available for the nine sensing
modes listed in the table (left). All models boast o-
ring sealing which exceeds the NEMA 6P (IP67)
rating. The Q45X is designed to withstand wash-
downs to 1200 psi. Q45Xs are extremely rugged, with
VALOX® housingsandmoldedacryliclenses. Mini-
style quick disconnect (QD) fittings are standard,
and allow the user to choose mating 5-wire cable to
exactly fit the interfacing requirements (see pages 5
and 6).
