D MINI-BEAM(R) Sensors SM312D MINI-BEAM Installation and Alignment Proper operation of the SM312D sensor requires that it be mounted securely and aligned properly. Excessive movement or vibration can result in intermittent or false operation caused by loss of alignment. For best results, final-mount the SM312D in an 18mm-hole by its threaded barrel or use a mounting bracket (see page 6). 1) Begin with the sensor at the desired distance from the object to be sensed, and at the approximate position where it will be mounted. The background should be as far behind the object as possible (at least three times the distance of the sensor from the object), and as dark a color as possible compared to the object. Ideally, the object should present its largest reflective surface to the sensor. Diffuse Mode Alignment Ob jec t SM312D 2) Apply power to the sensor, and advance the 15-turn GAIN control to maximum (clockwise end of rotation). The GAIN control is clutched at both ends to avoid damage, and will "free-wheel" when either end point is reached. Up Ri If the sensor is "seeing" its reflected light, the sensor alignment LED should be "on". Move the sensor up-down-right-left (include angular rotation) to obtain the fastest receiver LED pulse rate. If a pulse is not observable (too fast to count), reduce the GAIN control (counterclockwise rotation) to obtain a countable pulse rate. 3) Repeat the alignment motions after each GAIN reduction. When you have found the sensor orientation that produces the fastest pulse rate, mount the sensor solidly in that position. Increase the receiver GAIN to maximum. Test the system by removing the object from the sensing position. The receiver LED indicator should go "off". If the LED indicator does not go "off", the sensor is reacting to light reflected from a background surface. Reduce the GAIN setting until the alignment indicator goes "off", plus two additional full turns. Again place the object in the sensing position. If the alignment indicator does not come "on", the sensor is receiving as much or more light energy from the background as from the object. Consider the following alternatives: a) tilt the sensor or the background so that the sensing beam is not perpendicular to the background. ft wn Do SM312D 15 Turn Gain Adjustment and Light/Dark Operate Switch* Gasketed Acrylic Cover move the sensor closer to the object and reduce the sensitivity (GAIN); b) reduce background reflectivity by painting the background with flat-black paint, or by scuffing the background or cutting a hole through it; c) Le "AID" Indicator LED Lights when the sensor sees its own modulated light and pulses at a rate proportional to the strength of the received light signal. * Note regarding Light/Dark operate switch: * Turn switch fully clockwise for light operate (sensor outputs conduct when sensing light is received) * Turn switch fully counterclockwise for dark operate (sensor outputs conduct when sensing light is not received) Banner Engineering Corp. * Minneapolis, U.S.A. page 2 www.bannerengineering.com * Tel: 763.544.3164 gh t MINI-BEAM(R) Sensors SM312D MINI-BEAM DC Sensor 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 150mA maximum each output at 25C, derated to 100 mA at 70C (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.

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).
