ac/dc sensors with e/m relay output and optional timing logic

Q85s are compact, economical, polarized retroreflective mode pho-

toelectric 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 emit-

ted light and filters out unwanted reflections, allowing use in many

applications that are otherwise unsuited to retroreflective sensing.

The Q85's maximum range of 15 feet (4,6 meters) is obtained us-

ing the Banner model BRT-3 3" diameter round retroreflector. 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 on-

delayed 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 reflection 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

with ultrasonically-welded acrylic lenses. A gasketed ABS cover

protects the wiring chamber and the timing and sensitivity adjust-

ment 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 mount

ing bracket and

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

included.

Sensing range:

3 inches (8 cm) to 15 feet (4,6 meters) when used with Banner model

BRT-3 3" reflective 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 Configurations:

Q85VR3LP = SPDT e/m relay, on/off output

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

Output relay specifications

:

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 configured 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.
