Printed in USA P/N 03375L7G MINI-BEAM(R) Sensors SM2A312F MINI-BEAM Features * 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 Red LED Lights when the sensor's output is conducting 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 Lens Size Focal Length Housing Notes 12.5 mm (1/2") 12.5 mm (1/2") Aluminum Suitable for all but highly corrosive environments Delrin Maximum operating temperature is 100 C (212 F) 25 mm (1") 44 mm (1.7") L16FAL 25 mm (1") 44 mm (1.7") Aluminum Suitable for all but highly corrosive environments L16FSS 25 mm (1") 44 mm (1.7") Stainless Steel Suitable for all environments End of Fiber Optic Bundle Lens Housing Illuminate Opposite End Lens Focus 5/16" Threaded Sensing Tip Focal Length of Lens 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. page 2 MINI-BEAM(R) Sensors SM2A312F MINI-BEAM AC Product Specifications Supply Voltage and Current 24 to 240V ac (50/60 Hz), 250V ac max Supply Protection Circuitry Protected against transient voltages Output Configuration SPST SCR solid-state relay with either normally closed or normally open contact (light/dark operate selectable); 2-wire hookup Output Rating Minimum load current 5 mA; maximum steady-state load capability 300 mA to 50C ambient (122F) 100 mA to 70C ambient (158F) Inrush capability 3 amps for 1 second (non repetitive); 10 amps for 1 cycle (non repetitive) Off-state leakage current less than 1.7 mA rms On-state voltage drop 5 volts at 300 mA load, 10 volts at 15 mA load Output Protection Circuitry Protected against false pulse on power-up Output Response Time 8 milliseconds on and off "OFF" response time specification does not include load response of up to 1/2 ac cycle (8.3 milliseconds).
