3 / 8 page page 3 MINI-BEAM ® Sensors SM312D Banner Engineering Corp. • Minneapolis, U.S.A. www.bannerengineering.com • Tel: 763.544.3164 MINI-BEAM DC Sensor Specifications Certifications 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 150mA 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) less than 1 volt at 10 mA and less than 2 volts at 150 mA Output saturation voltage (NPN output) less than 200 millivolts at 10 mA and less than 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 a “dark” signal of 1 millisecond or longer duration, 500 Hz max. 0.3 millisecond response modification is available. See note below. 100 millisecond delay on power-up: outputs are do not conduct during this time. NOTE: DC MINI-BEAMs may be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers (e.g. - SM312DMHS). This modification reduces sensing range (and excess gain). Repeatability 0.3 milliseconds. Response time and repeatability specifications are independent of signal strength. Adjustments LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment potentiometer (clutched at both ends of travel). Both controls are located on rear panel of sensor and protected by a gasketed, clear acrylic cover. Indicators Exclusive, patented Alignment Indicating Device system (AID™, US patent #4356393) lights a rear-panel mounted red LED indicator whenever the sensor sees a "light" condition, with a superimposed pulse rate proportional to the light signal strength (the stronger the signal, the faster the pulse rate). Construction Reinforced PBT thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses, and 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 ft) or 9 m (30 ft) cables, or 4-pin euro-style quick disconnect (QD) fitting are available. QD cables are ordered separately. See page 8. Operating Temperature Temperature: -20° to +70°C (-4° to +158°F) Maximum relative humidity: 90% at 50°C (non-condensing) Application Notes 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. |
