1 Digital Fiber-Optic Sensors X-AG Series Easy operation and high performance for a variety of applications Dual display shows incoming and preset value side by side. High sensitivity and ultra long distance (1,0mm with the standard F-T00 thru scan fiber in high power mode) Three types of auto-tuning: -point, BGS and % Ro-compliant EXPLANATION OF MAJOR FUNCTIONS AND FEATURES CLICK Easy-to-use design Dual display panel The digital dual display panel indicates incoming and preset value side by side, so it is easy to check current scanning status while setting the sensor. The button layout is especially designed to ensure easy operation of gang-mounted sensors. Auto-tuning button Preset value Function selection button Output indicator + Button - Button Easy operation With controls that are as easy to operate as a conventional potentiometer, and with easy-to-read digital display, settings can be changed directly in RUN mode. Digital manual tuning APC ensures stable light emission level Auto Power Control (APC, light emission level control) monitors the level of light emitted by the LED, and regulates the current to maintain light emission at a constant level. Long and short term stabilization Stability when power is first supplied is also improved. Note: APC controls the light emission level of the LED emitter, but does not compensate for a drop in received due to other factors. Light emission level Without APC circuit Time 1

2 Advanced scanning performance for expanded possibilities High sensitivity and ultra long distance High-level performance is achieved with the built-in APC. Five selectable sensing modes Five sensing modes are selectable by desired response speed and sensitivity, according to what is best for your application. Sensing mode: Response speed: ms 1,0mm High sensitivity high power ms normal 1ms With F-T00 standard thru scan fiber unit. Scanning distance semi-fast 00µs fast 0µs high speed 0µs High speed High accuracy detection Note: Under optimum conditions With 1mm core dia. F-T00 standard fiber unit With 1mm core dia. F-T00 standard fiber unit With F-D04 coaxial fiber unit Countermeasures for short-distance saturation New countermeasures have been added since the sales release of the X Series. Even for small difference detection at short distances or for a high reflection ratio on both target object and background, X sensors deliver reliable detection performance. With a target object Without a target object Target object Background SATURATION Saturated Cannot be set Short distance anti-saturation mode Settable

3 Easy to operate Easy auto-tuning Percent (%) tuning Fewer tuning man-hours Patent Pending For re-tuning on the same application, simply press the AUTO button in the % tuning setting mode. Fewer detection errors due to setting variations With a target object Without a target object Example: % tuning at 9% For the same environment or target object, the ratio of two tuning levels with and without a target object is approximately the same. The setting range for % tuning without a target object is to 999%. Easy re-tuning Detection of remaining chips... Setting can be based on the background with no chips present. % setting at 7%. Tuning without a target object. Preset value is set to 00. Detection of liquid level... Tuning can be done only with no liquid present. Preset value Operated without liquid Lates, if the background darkens... Initial % setting at 0%. If inside wall of pipe becomes stained. Preset value An LO signal is used for chip supply. Re-tuning at 7% without a target object. Preset value is now. Re-tuning at 0% When used with incoming without liquid. Remote tuning BGS or % tuning can be done remotely from a connected device. Even when the is dropping due to a change in tooling, application environment, or installation conditions, stable and highly accurate detection can be assured by periodic re-tuning. Flexibility for tooling changes Long-term reliability ON PUSH! Environment has worsened due to paper powder. For remote full auto-tuning, use the X-AG0 series. Remote tuning

4 On-delay/one-shot Superior timer functions The advanced functions of the X-AG's combination timer go beyond the standard on-delay/off-delay functions and the newer one-shot timer function. Time chart LO (light ON) Timer setting time On-delay Off-delay Light ON Dark Timer setting range 0µs / 00µs ms to ms 6ms to 99ms 0ms to 900ms 1s to s Setting unit 00µs 1ms 0ms 1s One-shot OFF On-delay/off-delay Heartbeat Patent Pending ON-delay and one-shot output are repeated at regular intervals while an object is detected. Detection status Output status Example application: In chip sorting, an air jet is repeated at regular intervals until a rejected chip is removed. Output latch When an object is detected (or is not detected), latched output is turned ON, and remains ON no matter what the detection status is. Used for interlock During operation, the amplifier display blinks.

For more precise light axis alignment Selectable peak / bottom display modes Peak hold & Peak Peak Bottom hold & Peak hold & Bottom hold Hold time can be selected from s, s, and unlimited. Display type selection Relative incoming light intensity (instead of absolute) can also be displayed with the preset value. Preset value Relative intensity light level is 00 The incoming is indicated as a percentage of the preset value (= 0%). Scanning status can be managed by ratio. Key lock is toggled ON/OFF as shown below. Key lock function Key lock can be set for all keys, or for all except tuning keys. Key lock cancellation Accidental key-press prevention Displayed value shift function This function compensates for variation in the incoming.

7 Environment-friendly design Ro Directive compliance Yamatake products are developed to meet Ro directives restricting the use of hazardous substances such as lead, mercury, cadmium, hexavalent chromium heavy metals, and the brominated flame retardants PBB and PBDE. For example, non-halogen type flame retardants that do not generate dioxin are used, and the polyethylene used for packing material does not generate hazardous gas even if it is burned. Selection of standard 1, and m cables Optimum cable length can be selected for reduced waste. Monitor sleep mode for low power consumption The digital display can be set so that all display is off.in monitor sleep mode, power consumption can be reduced to 00mW. Since 1-segment display remains on, the power supply condition can still be checked. The Ro Directive Ro is European environmental directive. The name is an abbreviation for Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. When monitor sleep mode is enabled, sleep mode begins whenever there is no normal mode operation for seconds. When any button is depressed, normal operation mode resumes. One segment display changes in a fixed cycle.

BASIC PRECAUTIONS Wiring If an extension is necessary, use cable at least 0.mm in dia. and at most 0m long. If the wires of photoelectric sensor are laid in the same conduit as high-voltage or power lines, inductance may cause malfunction or damage. Isolate the photoelectric sensor's cable or lay it in a separate conduit. When using a commercially available switching regulator, ground the frame ground and ground terminals. If used without grounding, switching noise may cause malfunction. When using a load which generates an inrush current above the switching capacity, such as a capacitive load or incandescent lamp, connect a current-limiting resistor between the load and the output terminals. (Otherwise, the output short-circuit protection function will be activated.) Handling Output is disabled upon power-up for approx. 0ms until the unit stabilizes. When used in an environment with much dust, be sure to take countermeasures to keep dust away from the sensor head by using a sealed case or air purge. Use a cover or change the mounting direction to ensure the sensor's correct operation if interference from ambient light is considerable. Even when oil-resistant cable is used, do not use in a location subject to continuous splashing by water or oil, or where the unit is dipped in liquid. Ensure that the end of the cable is not subject to splashing by water or oil. Water or oil splashed on the fiber head may cause incorrect operation. Shield the sensor head to prevent direct splashes. Do not use where exposed to chemicals (organic solvents, acids, alkalis, etc.) To clean the sensor head, wipe lightly with a soft, clean cloth. Do not use an organic solvent such as benzine or paint thinner. Pulling with excessive force may break the cable. Do not apply a force of more than 0N. Do not bend the part of the cable nearest to the amplifier beyond the bend radius of 0mm. Avoid continuous bending stress. The detection distance or display value may vary depending on variations in the individual amplifier, installation circumstances, and/or type of fiber unit. 16
