See page 5 for more information. iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information. iv) May be ordered with 0.3 millisecond on/off response by adding suffix "MHS" to the model numbers (e.g., SM312FMHS). This modification reduces sensing range (and excess gain). Printed in USA 05/01 P/N 03368 rev. E MINI-BEAM(R) Sensors SM312F MINI-BEAM Features SM312F * Note regarding Light/Dark operate switch: 15 Turn Gain Adjustment and 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) Gasketed Acrylic Cover "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. MINI-BEAM Fiber Information Retaining Clip 1) Install the O-ring (supplied with the fiber) on each fiber end, as shown in the drawing. 2) While pressing the fiber ends firmly into the ports on the front of the sensor, slide the U-shaped retaining clip (supplied with the sensor) into the slot in the sensor's barrel, until it snaps into place. O-ring Lens Attachment Lenses are sometimes added to fiber optic assemblies for extending opposed mode sensing range. Banner ofers the following lens assemblies for use with fiber optic assemblies which have 5/16" -24 threaded sensing tips (e.g. fiber model IT23S): Model L9 L16F L16FAL L16FSS Lens Size Focal Length Housing Notes 12.5 mm (0.5") 12.5 mm (0.5") Aluminum Suitable for all but highly corrosive environments 25 mm (1") 25 mm (1") 25 mm (1") 44 mm (1.7") 44 mm (1.7") 44 mm (1.7") Delrin Maximum operating temperature is 100 C (212 F) Aluminum Suitable for all but highly corrosive environments Stainless Steel End of Fiber Optic Bundle Lens Housing Illuminate Opposite End Lens Focus 5/16" Threaded Sensing Tip Focal Length of Lens Suitable for all environments Lenses are most efficient when they are located slightly beyond their focal length distance from the sensing end of the fiber optic bundle. The easiest way to focus a lens is to treat it like a magnifying glass. Illuminate the fiber optic bundle at the threaded end of the fiber optic assembly by directing the opposite end toward a visible light source (e.g. - an incandenscent bulb, visible LED, sunlight, etc.). Thread the lens onto the fiber optic assembly until the end of the fiber optic bundle comes into sharp focus under the lens. Then, back off (unthread) the lens assembly from the point of sharpest focus by one to three full turns. The illuminated bundle should now appear slightly blurred. This is the optimum setting, and the lens may be secured in position using one of the jam nuts provided. Refer to the drawing above.

See note below. 100 millisecond delay on power-up: outputs 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., SM312FMHS). 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 (AIDTM, 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 5. Operating Temperature Temperature: -20 to +70C (-4 to +158F) Maximum relative humidity: 90% at 50C (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.
