Q85s are compact, economical, polarized retroreective mode pho­toelectric sensors in rugged NEMA-6P rated ABS housings. They
are ideally suited to conveyor control and similar applications. The
timing logic functions offered in the "T9" models provide additional
control capabilities over and above the basic model's ON/OFF (no
delay) function. The special lens of Q85 sensors polarizes the emit­ted light and lters out unwanted reections, allowing use in many
applications that are otherwise unsuited to retroreective sensing.
The Q85's maximum range of 15 feet (4,6 meters) is obtained us­ing the Banner model BRT-3 3" diameter round retroreector. All
Q85 sensors feature a convenient wiring chamber with two conduit
entrances for ease of connection, positioning, and mounting.

Q85 Series sensors operate from either 24-240V ac or 12-240V dc
and draw 2 watts maximum. They have SPDT electromechanical
relay output, and are available with a choice of either ON/OFF or
programmable timing output logic. Models with programmable
timing logic ("T9" models) provide eight switch-selectable logic
functions: ON/OFF (no delay), ON delay, OFF delay, ON/OFF
delay, one-shot (pulse), on-delayed one-shot, limit timer, and on­delayed limit timer. The adjustable time range for delay functions
and pulse length is 0.1 to 5 seconds (see page 2).

Two top-mounted LED indicators are provided. A red indicator
(Banner's exclusive, patented AID™ system*) lights whenever
the sensor "sees" the reection of its own modulated light source,
and pulses at a rate proportional to the strength of the received
light signal. A yellow output indicator lights whenever the Q85's
output is energized.

Q85 Series sensors have rugged yellow Cycolac® ABS housings
with ultrasonically-welded acrylic lenses. A gasketed ABS cover
protects the wiring chamber and the timing and sensitivity adjust­ment controls. Two 1/2-14 NPSM conduit entrances are provided;
a plug and gasket are included for a possible unused entrance. Q85
Series sensors are rated NEMA 1, 2, 3, 3S, 4, 4X, 6, 6P, 12, and
13 (IEC IP67). An 11-gauge plated steel mounting bracket and

two plated mounting bolts and nuts (see photo and page 2) are
included.

Specications, Q85 Series Polarized Retro Sensors

Sensing range:

3 inches (8 cm) to 15 feet (4,6 meters) when used with Banner model
BRT-3 3" reective target.

Sensing beam: visible red, 680 nanometers (polarized).
Supply voltage: 24 to 240V ac, 50/60 Hz or 12 to 240V dc (2 watts

maximum). No polarity for power supply hookup.

Models and Output Congurations:

Q85VR3LP = SPDT e/m relay, on/off output
Q85VR3LP-T9 = SPDT e/m relay, with programmable timer

Output relay specications:

Maximum switching power (resistive load): 90W, 750VA. Install
transient suppressor (MOV) across contacts that switch inductive loads.
Maximum switching voltage (resistive load): 250V ac or 30V dc.
Maximum switching current (resistive load): 3A.
Minimum voltage and current: 5V dc, 10 mA.
Mechanical life: 50,000,000 operations.
Electrical life at full resistive load: 100,000 operations.
Maximum switching speed: 25 operations per second.
Closure time (no timing logic in use): 20 milliseconds max.
Release time (no timing logic in use): 20 milliseconds max.
Repeatability (no timing logic in use): 1 millisecond.

All sensors are protected against false pulse on power-up. (False pulse
protection circuit causes a 100 millisecond delay on power-up.)

Adjustments: All models have a single-turn SENSITIVITY control

potentiometer, accessible beneath the ABS wiring chamber cover (T9
models also have a light/dark operate switch). Timing logic (T9 models
only) is congured at a DIP switch. Pulse length and delay are set by a
single-turn potentiometer (accessible under the wiring chamber cover).
The adjustable time range for both functions is 0.1 to 5 seconds; both
functions are automatically set to the same value.

Status Indicators: LEDs, one red and one yellow, both top-

mounted.
Red AID™ system (Alignment Indicating Device, US patent #4356393)
indicator LED lights whenever the sensor "sees" its own modulated light,
and pulses at a rate proportional to the strength of the light signal.

Yellow indicator lights whenever the sensor's output is energized.

Construction:

Yellow Cycolac® ABS housing, plated steel hardware. Acrylic lens.
ABS cover for wiring/adjustments access. Rated NEMA 1, 2, 3, 3S, 4,
4X, 6, 6P, 12, and 13; IEC IP67. It is the customer's responsibility to
maintain NEMA 6P integrity at the conduit entrance(s) in use. Maximum
wire size (for connection to wiring terminals) is #14 AWG.

Operating temperature range: -25° to +55°C (-13° to +131°F).
Maximum relative humidity: 90% at 50°C (non-condensing).

Hookup and timing logic selection

Hookup to the ac line and the external load is made at the ve terminals

inside the wiring chamber (see drawing below). There is no polarity for
power supply hookup. Output is an SPDT electromechanical relay.

Timing logic

programming

switch detail:

The output timing logic function (on sensor models with T9 model
number sufx) is selected at the timing logic programming switches,
according to the table (right). The output timing logic delays are set at

the single-turn time adjustment potentiometer. When the timing function
involves more than one time (as in ON and OFF delay, ON-delayed
one-shot, and ON-delayed limit timer functions), the potentiometer sets
both times to the same value.

Logic function Switch: SW1 SW2 SW3

ON and OFF delays (both) 0 0 0
ON delay (only) 0 0 1
OFF delay (only) 0 1 0
No delays 0 1 1
ON delayed one-shot 1 0 0
ON delayed limit timer 1 0 1
One-shot 1 1 0
Limit timer 1 1 1

With the light/dark operate switch (T9 models) set to light operate
(L.O.), the sensor's electromechanical output relay is energized when
the sensor sees the reection of its own modulated light. In the dark
operate (D.O.) position, the output is energized when the sensor does
not see the reection of its modulated light source.

Sensor sensitivity is set at the single-turn sensitivity adjustment po­tentiometer.
