WARNINGIf you ignore the advice with this mark, death or serious injury could result.CAUTIONIf you ignore the advice with this mark, injury or material damage could re-sult.In this Instruction Manual, and are indicated de-pending upon the level of danger. Please observe them strictly for thesafe use of this sensor.WARNING CAUTIONHazard IndicationsWARNING٨ Installation of a touch bumperYou are requested to always install a touch bumper when this product isused on an automatic guided vehicle (AGV).CAUTION٨ Use outside JapanThis sensor conforms to the EMC directive. However, it is not certifiedby a competent body in accordance with other country safety standards.Since each country has its regulations, please follow the local and na-tional regulations of the country where this sensor is used.CAUTION٨ Fail-safe measuresThis sensor is meant for proximity detection and does not possess con-trol functions for safety maintenance.If fail-safe measures are required, consider their incorporation in the to-tal system.Further, do not connect the sensor output directly to a stopping mecha-nism (brake).CAUTION٨ Periodical maintenance checkThe person incharge must periodically confirm the performance of theproduct and maintain a record of such checks. In addition, wheneverthe operating environment of the product is changed due to systemmodification, etc., performance check must be done.MOUNTING2٨ The tightening torque should be1.2Nm or less.M4 screw with washers(Please arrange separately)Main sensor mounting bracket(MS-PX-2) (Accessory)M4 (length 8mm)screw with washers٨ Mount the sensor, horizontally, at least 300mmabove the floor, to avoid reflection from the floor.300mm or moreNotes: 1)2)The sensing range is specified for white non-glossy paper (300300mm).Obtain the current consumption by the following calculation.Current consumption = Power consumption ¸ Supply voltage(e.g.) When the supply voltage is 12V, the current consumption (operating condition) is:1.5W ¸ 12V = 0.125A = 125mASPECIFICATIONS1Infrared LED (modulated)Emitting element0.3mm2 5-core cabtyrecable, 0.5m long(for input and output)For input and output:0.18mm2 9-core (PX-24ES and PX-23ES: 12-core) cabtyre cable, 0.5m longFor auxiliary sensor connection:0.18mm 2 10-core connector attached cabtyrecable, 0.5m longCableMS-PX-2 (Main sensor mounting bracket): 1 set, Adjusting screwdriver: 1 pc.Matrix chart for sensing areas and external inputs 1 sheet (PX-24ES and PX-23ES only)Accessories170g approx. 210g approx. 220g approx. 210g approx.WeightContinuously variable adjusters (OUT 1, adjacent right OUT 1, adjacentleft OUT 1 and OUT 2 areas are adjusted independently.)Sensitivity adjusterOptical interference from up to 25 units is prevented.Automatic interferenceprevention functionIP65 (IEC)Protection-10 to +55͠ (No dew condensation or icing allowed), Storage: -20 to +70͠Ambient temperature35 to 85% RH, Storage: 35 to 85% RHAmbient humidityEnclosure: ABS, Lens: Acrylic, Cover: PolycarbonateMaterialRed LED (lights up when the beam is received in the effective OUT 1 areas)OUT 1 area operation indicatorYellow LED (lights up when the beam is received in the effective OUT 2 areas)OUT 2 area operation indicatorFour sensing areas are selectablewith dip switches.Four sensing areas areselectable with dipswitches, and eight sens-ing areas are selectablewith external inputs.Sensing area FixedSensitivity of all areas (except auxiliary areachanges simultaneously in response to theexternal analog voltage input (0 to +5V)External sensitivityadjustment input 㧙Connected to 0 to +1V or GND (0V):Auxiliary area ineffectiveConnected to 4.5 to 31V, or open:Auxiliary area effectiveRight OUT 1 auxili-ary area cancel inputLeft OUT 1 auxiliaryarea cancel input㧙80ms or lessResponse time㧙㧙Output operation㧙ON when modulated beam other than its own(including auxiliary sensor's light is receivedShort-circuit protectionNPN open-collector transistorMaximum sink current: 100mAApplied voltage: 40V DC or less(between extraneous light monitor output and 0V)Residual voltage: 1.5V or less (at 100mA sink current)0.4V or less (at 16mA sink current)Extraneous lightmonitor outputConnected to 0 to +1V or GND (0V): Sleep conditionConnected to (supply voltage - 1V) to 31V, or open: Operational conditionSleep input㧙Output operationIncorporatedSelectable either Light-ON or Dark-ON with a switch (Output operation ofOUT 1 and OUT 2 is the same.)Short-circuit protectionNPN open-collector transistorMaximum sink current: 100mAApplied voltage: 40V DC or less (between OUT 1 / OUT 2 and 0V)Residual voltage: 1.5V or less (at 100mA sink current)0.4V or less (at 16mA sink current)OUT 1OR circuit among the ef-fective center, left, right,adjacent left / right OUT1 areas and the effectiveauxiliary left / right areasOUT 2OR circuit among theeffective center, left,and right OUT 2 areas15% or less of operation distanceHysteresisUnder operation: 1.5W or less, Under sleep condition: 0.3W or less(without auxiliary sensor)Power consumption(Note 2)10 to 31V DC including rippleSupply voltage3m 1m 3m 1m 5mSensing range (Note 1)(OUT 1 and OUT 2 areas)PX-22 PX-21 PX-24 PX-24ES PX-23ES PX-26Type Standard modelShort sensing range Short sensing rangeLong sensingrangeAuxiliary sensor connectable modelWith external control functionModel No.ItemOutputsInputsThank you very much for purchasing Panasonic products.
