SM312CVQD Datasheet, PDF (3/3 Pages) List of Unclassifed Manufacturers – Self-contained photoelectric sensors

MINI-BEAM^® dc-Voltage Series
Installation
Specifications
Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA
(exclusive of load)
Supply Protection Circuitry
Protected against reverse polarity and transient voltages
Output Configuration
Bipolar: One current sourcing (PNP) and one current sinking (NPN) open collector
transistor
Output Rating
150 mA maximum each output at 25° C, derated to 100 mA at 70° C
(derate ≈ 1 mA per ° C)
OFF-state leakage current: less than 1 microamp
Output saturation voltage (PNP output): < 1 volt at 10 mA, < 2 volts at 150 mA
Output saturation voltage (NPN output): < 200 millivolts at 10 mA, < 1 volt at 150 mA
Output Protection Circuitry
Protected against false pulse on power-up and continuous overload or
short-circuit of outputs
Output Response Time
Sensors will respond to either a “light” or “dark” signal of 1 millisecond or longer duration,
500 Hz maximum. Modification for 0.3 millisecond response is available (MHS-suffix
models; these models also feature reduced sensitivity range and reduced repeatability.)
NOTE: Outputs are non-conducting during 100 millisecond delay on power-up.
Repeatability
Opposed: 0.14 milliseconds
Non-Polarized and Polarized Retro, Diffuse, Convergent, Glass Fiber Optic, and
Plastic Fiber Optic: 0.3 milliseconds
Response time and repeatability specifications are independent of signal strength.
Adjustments
Light/Dark Operate Select switch
15-turn slotted brass screw Gain (sensitivity) adjustment potentiometer (clutched at both
ends of travel)
Located on the rear panel, protected by a gasketed, clear acrylic cover.
Indicators
Patented alignment Indicator Device system (AID™, US patent #4356393) lights a rear-
panel-mounted LED indicator when the sensor sees light. Its pulse rate is proportional to
the light signal strength (the stronger the signal, the faster the pulse rate).
Construction
Reinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic
lenses, stainless steel screws
Environmental Rating
Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67.
Connections
PVC-jacketed 4-conductor 2 m (6.5') or 9 m (30') cables, or 4-pin Euro-style QD fitting;
QD cables available separately.
Operating Conditions
Temperature: -20° to +70°C (-4° to +158°F)
Maximum relative humidity: 90% at 50°C (non-condensing)
Application Note
The NPN (current sinking) output of dc MINI-BEAM sensors is directly compatible as an
input to Banner logic modules, including all non-amplified MAXI-AMP and MICRO-AMP
modules. MINI-BEAMs are TTL compatible.
