MINI-BEAM SM312FV Visible-light Glass Fiber Optic DC Sensors Used with Banner Glass Fiber Optic assemblies for specific applications including the following: color registration sensing in the diffuse mode (except for red-on-white contrast, which requires a green or blue light source) presence sensing of translucent materials and registration mark sensing on clear webs in the opposed mode Compact, modulated, self-contained fiber optic sensors for 10-30V dc operation Useable in opposed, retroreflective, and diffuse fiber optic modes with Banner glass fiber optic assemblies Switch-selectable for light operate or dark operate Includes Banners exclusive AID alignment system US patent number 4356393 Visible red, 650 nm MINI-BEAM Glass Fiber Optic Models Supply Output Excess Gain Beam Pattern Models Range Cable* Voltage Type Diffuse mode performance based on 90% reflectance white test card 1000 SM312FV E X Opposed Mode SM312FV C 75 mm 3 in 100 E Opposed Mode 50 mm 2 in S 25 mm 1 in S IT23S Fiber 0 0 IT13S IT23S 10 G IT13S Fiber 25 mm 1 in A 50 mm 2 in I N 75 mm 3 in 1 Range 1 mm 10 mm 100 mm 1000 mm 0 50 mm 100 mm 150 mm 200 mm 250 mm varies by .04 in .40 in 4.0 in 40 in 2 in 4 in 6 in 8 in 10 in DISTANCE DISTANCE sensing SM312FV 2 m (6.5 ) Bipolar mode 10-30V dc SM312FVQD 4-Pin Euro QD NPN/PNP 1000 and fiber SM312FV E optics X Diffuse Mode SM312FV used C 1.95 mm 0.075 in Diffuse Mode 100 E 1.30 mm 0.050 in S 0.65 mm 0.025 in S 0 BT13S BT23S 0 10 BT23S Fiber G 0.65 mm 0.025 in A 1.30 mm 0.050 in I BT13S Fiber 1.95 mm 0.075 in N 1 0 5 mm 10 mm 15 mm 20 mm 25 mm .1 mm 1 mm 10 mm 100 mm 0.2 in 0.4 in 0.6 in 0.8 in 1.0 in .004 in .04 in .40 in 4 in DISTANCE DISTANCE *NOTES: i) 9 m (30 ) cables are available by adding suffix W/30 to the model number of any cabled sensor (e.g., SM312FV W/30). ii) A 150 mm (6 ) long pigtail cable with attached QD connector is available by adding suffix QDP to the model number of any MINI-BEAM sensor (e.g., SM312FVQDP). 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., SM312FVMHS). This modification reduces sensing range (and excess gain). Printed in USA 05/01 P/N 03510 rev. C MINI-BEAM Sensors SM312FV MINI-BEAM Features SM312FV 15 Turn * Note regarding Light/Dark operate switch: Gain Adjustment Turn switch fully clockwise for light operate (sensor outputs conduct when and Light/Dark sensing light is received) Operate Switch* Gasketed Turn switch fully counterclockwise for dark operate (sensor outputs conduct when Acrylic Cover sensing light is not received) 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 1) Install the O-ring (supplied with the fiber) on each fiber end, as shown in the Retaining Clip drawing. 2) While pressing the fiber ends firmly into the ports on the front of the sensor, O-ring slide the U-shaped retaining clip (supplied with the sensor) into the slot in the sensors barrel, until it snaps into place. Lens Attachment Lenses are sometimes added to fiber optic assemblies for extending opposed mode sensing range. Banner offers the following lens assemblies for use with fiber optic assemblies which have 5/16 -24 threaded sensing tips (e.g. fiber model IT23S): Model Lens Size Focal Length Housing Notes Suitable for all but L9 12.5 mm (1/2 ) 12.5 mm (1/2 ) Aluminum highly corrosive End of Fiber Optic Bundle Lens Housing environments Maximum operating Illuminate Opposite End L16F 25 mm (1 ) 44 mm (1.7 ) Delrin temperature is 100 C (212 F) Lens 5/16 Threaded Suitable for all but Sensing Tip Focus L16FAL 25 mm (1 ) 44 mm (1.7 ) Aluminum highly corrosive Focal Length of Lens environments Stainless Suitable for all L16FSS 25 mm (1 ) 44 mm (1.7 ) Steel 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 incandescent 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. Banner Engineering Corp.
