Q85 Series Sensors
2
Q85s are compact, economical, photoelectric sensors in rug-
ged NEMA-6P rated ABS housings. They are ideally suited
for conveyor control and similar applications. The timing
logic functions offered in the "T9" models provide additional
control capabilities over and above the ON/OFF (no delay)
function of the basic models. Q85 Series sensors are available
for the opposed, diffuse, and polarized retroreflective sensing
modes. The special lens of the Q85 polarized retroreflective
sensor polarizes the emitted light and filters out unwanted
reflections, allowing its use in many applications that are
otherwise unsuited to retroreflective sensing. All Q85 sensors
feature a convenient wiring chamber with two conduit en-
trances for ease of wiring, positioning, and mounting.
Q85 Series sensors are available in models to operate either
from 24-240V ac/12-240V dc or from 10-48V dc. AC/DC
models are available with either an SPDT electromechanical
output relay or an SPST solid-state switch. Q85VR3 Series
electromechanical relay models are capable of switching
250V ac, 30V dc, 3 amps (maximum values, resistive load).
Q85BW13 Series ac/dc solid-state output models switch up to
250V ac, 250V dc, 300 mA maximum.
Q85BB62 Series 10-48V dc-only models have switchable
light/dark operate solid-state NPN (current sinking) and PNP
(current sourcing) outputs, each capable of 150 mA maximum
continuous load. Also included on dc-only models is an
alternative low-saturation NPN output specially designed for
direct interfacing to TTL and similar circuitry.
Q85 Series sensors 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-de-
layed 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 pages 6 and 7).
Two top-mounted LED indicators are provided. A red indica-
tor (Banner's exclusive, patented AID™ system*) lights when-
ever the sensor "sees" its 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 hous-
ings 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
sealing 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 (cover photo
and drawing, page 5) are included.
WARNING... Q85 Series photoelectric pres-
ence 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 a safety device 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.
