C MINI-BEAM(R) Sensors SM312LV, SM312LVAG and SM312LP MINI-BEAM Installation and Alignment Proper operation of these sensors requires that they be mounted securely and aligned properly. For best results, final-mount these sensors in an 18 mm hole by their threaded barrel or use one of the available mounting brackets, (see pages 6 - 7). Retroreflective Mode Alignment 1) Begin with the sensor at the desired distance from the retro target and at the approximate position where it will be mounted. An object at the sensing position should pass through the "core" of the sensor's light beam. 2) Apply power to the sensor, and advance the sensor's 15-turn GAIN control to maximum (clockwise end of rotation). If the sensor is "seeing" the reflected light beam, the alignment LED should be "on". Move the sensor up-downright-left to obtain the fastest receiver LED pulse rate. (alternatively, the retro target may be moved.) If a pulse is not observable (too fast to count), reduce the GAIN control (counterclockwise rotation) to obtain a countable pulse rate. (As an aid to alignment, it may be necessary to further reduce the strength of the light signal by tape-masking a portion of the retroreflective target area.) ; @ A A ; @ A@;A@;A@; A@;A@;A@; A@;A@;A@; 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 (or reflector) solidly in that position. Increase the receiver GAIN to maximum. Test the system by placing the object to be detected into the sensing position. The indicator should go "off". If an "LV" model sensor's indicator does not go "off" at this point, the sensor is reacting to light reflected from the object ("proxing"). tro Re et g r Ta Move sensor (or target) to obtain the fastest receiver LED pulse rate. Up ft Le wn Do If proxing occurs, reduce the GAIN setting until the alignment indicator goes "off", plus two additional full turns. Remove the object from the sensing position and check that the alignment indicator LED comes "on" and pulses at a rate of at least two flashes per second. Confirm that the LED goes "off" when the object is replaced. Proxing can be avoided by mounting the sensor so that it's light beam is not perpendicular to any flat reflective surface on the object to be detected (an angle of 10 to 15 degrees is usually sufficient). Also, at distances of a few feet or more, using more than one reflector may increase sensing contrast between object-present and object-absent. 15 Turn Gain Adjustment and Light/Dark Operate Switch* Gasketed Acrylic Cover "AID" Indicator LED Lights when the sensor sees the reflection of its own modulated light and pulses at a rate proportional to 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 MINI-BEAM(R) Sensors SM312LV, SM312LVAG and SM312LP MINI-BEAM DC Product Specifications Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25mA (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 100mA at 70C (derate 1mA per C) Off-state leakage current less than 1 microamp Output saturation voltage (PNP output) less than 1 volt at 10mA and less than 2 volts at 150mA Output saturation voltage (NPN output) less than 200 millivolts at 10mA and less than 1 volt at 150mA 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, 500Hz max. 0.3 millisecond response modification is available.

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. Certifications NOTES: i) 9 m (30') cables are available by adding suffix "W/30" to the model number of any cabled sensor (e.g., SM312LP W/30). ii) Standard models have 1 millisecond output response; models with 0.3 millisecond (300 microsecond) response are available by adding suffix "MHS" to the model number (e.g., SM312LPMHS). Note that this modification reduces the maximum operating temperature to +50 C (122 F). iii) A 150 mm (6") long pigtail cable with attached QD connector is available by adding suffix "QDP" to the model number (e.g., SM312LPQDP). iv) A model with a QD connector requires an optional mating cable (see accessories, page 8).
