NOTE: Retroreflective range is specified using one model BRT-3 retroreflector (3-inch
diameter). Actual sensing range may be more or less than specified, depending upon the
efficiency and reflective area of the retroreflector(s) in use. See the Banner Photoelectric
Sensors catalog for more information on available retroreflectors.

QH23 Q23
For Q23 Plastic Fiber Sensing Mode:
i) The opposed range of Q23FP sensors using 1mm (0.4 in) plastic fibers may be extended using optional lens pairs. A pair of model L2 lenses extends the
opposed range to 2 m (80 in). A pair of model L08FP lenses extends opposed range to 3 m (10 ft). See the photoelectric sensors catalog for lens details.
ii) Diffuse mode sensing with Q23FPY models is generally not recommended due to low excess gain. If in doubt about sensing performance, contact
the factory Application Engineering Department or your local Banner Sales Engineer to discuss diffuse mode applications.

Q23 & QH23 Product Specifications
Certifications
Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA for diffuse, retro, and fiber optic models (exclusive of load)
Opposed emitters and receivers draw 20 mA each
Supply Protection Circuitry Protected against reverse polarity and transient voltages
0utput Configuration Solid-state dc complementary outputs:
Q(H)23SN6xx models = NPN sinking, N.O. (normally open) & N.C. (normally closed) complementary
Q(H)23SP6xx models = PNP sourcing, N.O. & N.C. complementary
Light operate: N.O. output conducts when the sensor sees its own modulated light source
Dark operate: N.C. output conducts when the sensing beam is blocked
The N.C. output may be used as an alarm output, depending upon hookup to the power supply (see
hookup diagrams)
Output Rating 150 mA maximum each in standard hookup; when wired for alarm output, the total load may not exceed 150 mA
Off-state leakage current less than 1 microamp at 30V dc
Output saturation voltage less than 1 volt at 10mA dc; less than 1.5V at 150 mA dc
Output Protection Circuitry Protected against false pulse on power-up, transient voltages, and continuous overload or short-circuit of outputs
Output Response Time 1 millisecond “on” and “off” (except for Q23FPY high-speed sensors which have 100 microsecond
response time); no false pulse on power-up
(NOTE: 100 millisecond delay on power-up: outputs are non-conducting during this time.)
Repeatability All Opposed Modes: 0.13 ms; Retro and Diffuse:0.25 ms; FPY High speed Plastic Fiber Optic:
25 microseconds Response time and repeatability specifications are independent of signal strength.
Adjustments SENSITIVITY control (single-turn, o-ring sealed potentiometer)
Indicators Sensors except opposed mode emitters have two LEDs:
GREEN glowing steadily = dc power “on”
GREEN flashing = output overload
YELLOW glowing steadily = normally open output is conducting
YELLOW flashing = marginal excess gain (1 - 1.5x), light condition; flashing YELLOW corresponds to
“on” state of alarm output
Emitters have green power “on” indicator
Construction Yellow and black ABS housing, with acrylic lens and clear ABS top cover, completely sealed. Stainless steel
mounting bracket and M3 mounting hardware are supplied
Environmental Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67. Housing materials rated UL 94 V-0
Connections PVC-jacketed 4-conductor 2 m (6.5 ft) or 9 m (30 ft) cables, or 6-inch pigtail with 4-pin pico-style quick
disconnect (QD) fitting are available. Mating QD cables are ordered separately. See Accessories.
Operating Temperature Temperature: -20° to +55°C (-5° to +131°F)
Maximum relative humidity: 90% at 50°C (non-condensing)
Quick Disconnect (QD) Option
Q23 & QH23 sensors are sold either with a 2 m (6.5 ft) or 9 m (30 ft) attached PVC-covered cable or with a 4-pin pico-style QD connector on a 150 mm
(6 in) cable pigtail.
Q23 & QH23 QD sensors are identified by the letter “Q” in their model number suffix. Mating cables for QD sensors are model PKG4-2 (straight connector)
or PKW4-2 (right-angled connector). Cables are supplied in a standard length of 2 m (6.5 ft). For more information on QD cable, see Accessories.
Application Note To avoid damage to the sensor caused by static discharge (ESD), use the plastic screwdriver supplied
with each sensor (included in the hardware packet) to adjust the SENSITIVITY control. Otherwise, use a
screwdriver with an insulated handle.
