Economical opposed mode sensor pairs in leakproof 30-mm threaded
VALOX
® barrels; quad-ring sealed acrylic lenses
Ideal for high-humidity and high-pressure washdown applica-
tions such as laundries, car washes, and food processing
Sensing range of 60 meters (200 feet)
Totally self-contained; 10 to 30 volt dc operation
Complementary outputs: one normally open, one normally closed;
choice of NPN (sinking) or PNP (sourcing) configuration,
150 mA max. (continuous, each output)
One output may be used as a marginal signal alarm
SM30 Series EZ-BEAM
Opposed Mode Sensor Pairs
These are economical opposed mode sensor pairs in leakproof (NEMA 6P, IEC
IP67 rated) 30-mm threaded barrel VALOX
® housings. Their size, shape, leakproof
construction, mounting options, and price make them ideally suited for use in
applications which undergo high-pressure washdown, such as car washes and food
processing. Emitters and receivers must each be ordered separately (see below).
These sensors operate from 10-30V dc. Emitters draw 25 milliamps; receivers draw
20 milliamps maximum continuous, exclusive of load current. Receiver outputs are
complementary: one normally open (N.O.) and one normally closed (N.C.), each
capable of switching up to 150 milliamps (continuous). Receivers are available
with either NPN sinking or PNP sourcing outputs. Models with NPN (current
sinking) outputs are directly compatible as input devices to Banner logic modules,
including all of the non-amplified MAXI-AMP™ and MICRO-AMP
® modules.
The normally closed (N.C.) receiver output may be configured as a normally open
(N.O.) alarm output (US patent no. 5087838) by reversing the receiver's hookup to
the power supply. The alarm output conducts when the receiver's excess gain in the
light condition drops below 1.5x. An easily-visible, internally-mounted red
indicator LED lights when the receiver "sees" the
emitter's modulated light source, and flashes to
indicate marginal excess gain (1-1.5x) in the light
condition. The flashing LED corresponds to the
"on" state of the alarm output.
SM30 Series EZ-BEAM opposed mode sensors
are available with a 6-1/2 foot long attached PVC-
covered cable or a 4-pin euro-type QD fitting.
Mating QD cable must be purchased separately
(see Specifications section).
Electronics are fully epoxy-encapsulated for maxi-
mum resistance to mechanical shock and vibra-
tion. Positive sealing at both ends of the sensor
with no exposed epoxy interfaces eliminates all
leakage paths (including capillary leakage). The
acrylic lens is quad-ring sealed.
Leakproof 30-mm dc barrel sensors for demanding industrial applications
Lexan ® and VALOX ® are registered trademarks of General Electric Co.
Sensing range: 60 meters (200 feet).
Sensing beam: infrared, 880 nanometers.
Supply voltage: 10 to 30V dc at 25 mA for emitters (reverse polarity
protected); 20 mA max. for receivers, exclusive of load. 10% max. ripple.
Emitter model listing:
Use emitter SM306E (attached cable) or SM306EQ (euro-type QD fitting).
Receiver model listing and output configurations:
Solid-state dc complementary outputs:
SM30SN6R = NPN sinking, N.O. & N.C. (attached cable)
SM30SN6RQ = NPN sinking, N.O. & N.C. (euro-type QD fitting)
SM30SP6R = PNP sourcing, N.O. & N.C. (attached cable)
SM30SP6RQ = PNP sourcing, N.O. & N.C. (euro-type QD fitting)
Light operate: N.O. output conducts when the receiver sees the emitter's
modulated light source.
Dark operate: N.C. output conducts when the receiver does not see the emitter's
modulated light source. The N.C. (normally closed) output may be used as an
alarm output, depending upon hookup to the power supply.
Receiver output rating : 150 mA maximum (each) in standard hookup.
Short-circuit protected.
Off-state leakage current <1 microamp at 30V dc.
On-state saturation voltage <1V at 10 mA dc; <1.5V at 150 mA dc.
When wired for alarm output, the total load may not exceed 150 mA.
Specifications and model listings: Response time: 3 milliseconds "on"; 1.5 milliseconds "off". No false pulse
on power-up (false pulse protection circuit causes a 100 millisecond delay on
power-up). Repeatability 375 microseconds. Response time and repeatability
are independent of signal strength.
Indicators: Receivers have red LED which lights whenever the receiver
"sees" the emitter's modulated light source, and flashes to indicate marginal
excess gain (1-1.5x) in the light condition. Emitters have red LED which lights
to indicate DC POWER ON. Indicators are internally-mounted and are visible
both through the sensor's lens from the front and through a sealed side viewing
port near the lens.
Construction: M30x1.5 threaded VALOX ® tubular housing with positive
sealing at both ends. Completely sealed; epoxy-encapsulated circuitry. Quad-
ring sealed acrylic
lens. Exceeds NEMA 6P and IEC IP67 ratings. Two
VALOX ® jam nuts provided.
Cabling: 6-1/2 foot long (2 meter) attached PVC-covered 2-wire cable
(emitters) and 4-wire cable (receivers), or 4-pin QD cable as follows:
MQDC-415 cable for models with Q model suffix; 12 feet long,
straight euro-type QD connector
MQDC-415RA cable for models with Q model suffix; 12 feet long,
right-angled euro-type QD connector
Vibration and mechanical shock: meets Mil. Std. 202F requirements.
Method 201A (Vibration: frequency 10 to 60 Hz, max., double amplitude 0.06-
inch, maximum acceleration 10G). Method 213B conditions H & I (Shock:
75G with unit operating; 100G for non-operation).
