UZF36 0.6.8 15:55 Page 12 ANALOG OUTPUT TYPE OPTICAL FIBER PHOTOELECTRIC SENSOR UZF36 NEW ANALOG OUTPUT TYPE FOR DIVERSE APPLICATIONS Analog Voltage Output Various Uses Slim Incorporated with the analog voltage output (1 to 5V). The analog process with various kinds of fiber heads offers unique application solutions such as a height evaluation, or a gap detection. Space-effective as it is only 10mm .394inch thick. Only 10mm .394inch thick Automatic Crosstalk Prevention Function Two sets of fibers can be mounted close together or face to face. Saturation Indicator Saturation indicator lights up when the output reaches 5V, thereby its sensitivity is easily adjusted without using a tester. The incident beam indicator brightens up in proportion to the amount of incident beam (output voltage).

Detecting gap to boards No sensitivity setting is required even as products are changed over because of the differential sensing. Detecting irrelevant products Extraneous products are sorted out that differ from normal products in reflection ratio. Ascertaining the number of translucent films The number of translucent films overlaid is inspected by beam penetration. Sensing turbidity of liquid The turbidness of liquid inside a clearwall tank is analogically observed. Measuring inner diameter of rings Rings are classified according to inner diameter. 13 0.6.8 15:55 Page 14 ORDER GUIDE Amplifier Appearance Model No. Supply voltage Analog output UZF36 12 to 24V DC510% Analog voltage * Voltage output: 1 to 5V Fibers Long sensing range Type Shape of sensing probe (mm inch) Standard Small sensing probe Features 160mm * Sensing range is about double of that of 6.299 conventional modle inch Fiber optic cable length Free Cut 2m 6.562ft M4 With sleeve M4 85mm 3.346inch * Free cuttable type Free Cut 2m 6.562ft 2.5 .098 85mm 3.346inch * Same sensing range as the standard with a smaller sensing probe Free Cut 2m 6.562ft Small diameter M3 With sleeve M3 0.88 .035 Small diameter Standard Small sensing probe Small diameter Free Cut 2m 6.562ft * A long sensing range is achieved with a very 125mm 4.921inch small sensing probe 2.5mm .098inch M.591 Side sensing 65mm 2.559inch M 15 M .591 M6 Coaxial M6 With sleeve M6 Free Cut 2m 6.562ft 31mm 1.220inch 22mm .866inch * Arrayed beam does mot miss by detecting object regardless of its position UZFTF44 With sleeve 40mm 1.575inch * Long sensing range UZFTL8 Cut 2m 6.562ft Free Cut 2m 6.562ft UZFTA8E UZFR8B UZFRF8 * Free cuttable type Free Cut 2m 6.562ft M3 22mm .866inch UZFRF89 With sleeve 90mm 3.543inch 7mm .276inch UZFRT8 * Same sensing range as the standard with small sensing probe Free Cut 2m 6.562ft 22mm .866inch With sleeve M4 1.48 .058 UZFRF4 7mm .276inch * Suitable for sensing in the intricate apparatus * Free cuttable type Free Cut 2m 6.562ft 2.5 .098 M4 M3 UZFRF49 With sleeve 90mm 3.543inch UZFRF44 With sleeve 40mm 1.575inch UZFRS4 10mm .394inch Coaxial UZFRT4 UZFRS8 M4 Top sensing UZFTF49 With sleeve 90mm 3.543inch UZFRF84 3 .118 Lens applicable UZFTT8 With sleeve 40mm 1.575inch Small diameter Coaxial * Small diameter UZFTF84 With sleeve 40mm 1.575inch UZFTA8 Free 2.5 .098 Lens applicable With sleeve 90mm 3.543inch UZFTS4 M15 M4 High precision * Suitable for sensing in the intricate apparatus * Free cuttable type 23mm .906inch 2.5 .098 Long sensing range Array UZFTF89 UZFTF4 1.5 .059 Top sensing UZFTB8 UZFTS8 M3 Lens applicable Model No. UZFTF8 1.48 .058 Long sensing range with lenses Thru-beam Sensing range (*1) M4 Lens applicable Lens applicable Reflective 3mm .118inch * A highly precise positioning is possible with coaxial reflective mode * Approx. 0.3mm .012inch is achieved by means of combining with ultra-small spot lens UZFXMR3 Free Cut 2m 6.562ft 500mm 19.685inch UZFRG4 UZFREG1 M20 .787 UZFRA8 Array UZF36 13mm .512inch Side sensing M 20 M .787 * Arrayed beams meet various sensing demand Free Cut 2m 6.562ft UZFRA8E (*1) : The sensing range is defined as the range until the saturation indicator lights up.

Crosstalk prevention function * Two sets of fibers can be mounted close together that connected to the UZF36 amplifiers because of the crosstalk prevention function. Two sets of the UZF36 amplifiers should be set the wiring and switches on them as follows. Mounting How to mount the amplifier 1 Hook the rear part to the attached mounting bracket (UZF811) or DIN rail. 2 Press the amplifier down on the bracket or DIN rail. 2 1 Mountable close together DIN rail or the attached mounting bracket 1) Wiring * Connect both crosstalk prevention wires together under both 0V wires in common. How to remove the amplifier 1 Push the amplifier frontward. 2 With keeping on it, lift up the front part of the amplifier. 1 2 Color code (Brown)V (Blue) 0V V 0V (Black) Analog voltage output How to connect fiber cables 1 Unlock the fiber lock lever upright. 2 Insert fiber cables into the inlets slowly until fully deepened. 3 Lock the fiber lock lever on the original position.

To neglect crosstalk prevention function * If the amplifier is used singly, set the crosstalk prevention selection switch on "MAIN", otherwise it is not operable. * Insulate the crosstalk prevention wire. 0.6.8 15:55 Page 19 PRECAUTIONS FOR PROPER USE Amplifier Response time selection * The response time of the UZF36 can be selected either "1ms" or "10ms". If your detecting application does not need the quick response, "10ms" is recommended as it makes the detection secure against inductive noises and ambient lights. If you choose "1ms", pay attention to inductive noises and ambient lights. * The response time stands for the processing time that the output follows to an input change, either from the complete Dark level (1V) up to 90% extent of a certain Light level or from the Light level down to the complete Dark level 10% extent beforehand. The response time of the UZF36 is constant regardless of the amplitude of the output voltage. The usage with "10ms" is recommended to gain the output reliability if you do not require quick response. When you select "1ms", carefully consider the influence of extraneous lights or inductive noises. 4V(Light state) 3.7V (e.g.) 3V (Light state) 2.8V 1.3V 1V(Dark state) t1 t1 t2 t2 1.2V 1V (Dark state) Sensitivity adjustment Procedure (1) Sensitivity adjuster Adjusting Turn the sensitivity adjuster counterclockwise fully up to the minimum sensitivity.
