It carries a 1 millisecond response and a 500 Hz switching frequency, which is the bandwidth ceiling the receiver will hold on a high-speed conveyor or indexing table before the output starts to miss transitions. Output is PNP (light/dark selectable) into a maximum load current rated for typical 4-wire DC sensor service, terminated through an M12 4-pin DC micro male connector — the standard drop-in wiring pattern on most PLC digital input cards. The body is nickel-plated brass, threaded M18, sealed to IP67 with a PMMA lens, and the approvals on the data plate are UL, CSA and CE — which is what an inspector looks for when a sensor ships onto a washdown line or into a UL-listed panel. ## What the headline ratings decide 8 m sensing distance is the number that sets the application envelope: anything wider calls for a different XU receiver or a laser-class sensor, anything narrower is comfortably inside this part's range with margin to spare. 500 Hz switching frequency at 1 millisecond response is what decides whether this part fits a high-speed indexing application — it does; for slower presence detection it's simply more headroom than you'll use. ## Same-function cross-shop The closest functional alternative in the same XU2 thru-beam family is XU2S18PP340WD: same 8 m range, same 12 to 24 VDC, same PNP, same M12 4-pin DC micro male connector, same 500 Hz switching and 1 millisecond response — the only documented difference in the data is a 90 deg side sensing head orientation versus the axial head on the XU2S18PP340D, which is a panel-layout call rather than an electrical one.","metaTitle":"Square D XU2S18PP340D Photoelectric Sensor, 8 m, 24 VDC","metaDescription":"Square D XU2S18PP340D thru-beam photoelectric sensor, 8 m sensing, 12-24 VDC, PNP, IP67 M12 4-pin, sourcing to RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Photoelectric Sensors"],"specifications":{"UPC":"78590190739","Model":"XU2","title":"XU2S18PP340D","Used On":"XU2 SERIES THRU BEAM PHOTOELECTRIC SENSOR","Category":"Photoelectric Sensors","Material":"NICKEL PLATED BRASS","Enclosure":"IP67","Brand Name":"Preventa[T]","description":"Telemecanique XU2S18PP340D 18Mm Photo 24Vdc|SQUARE D XU2S18PP340D: 18MM PHOTO 24VDC","Construction":"THREADED","Sub-Category":"Tubular Photoelectric Through Beam Detector","UPC 12 Digit":"389110907202","Response Time":"1 MILLISECOND","Operating Mode":"LIGHT/DARK","Connection Type":"M12 4 PIN DC MICRO MALE CONNECTOR","lifecycle_stage":"current","Sensing Distance":"8 M","Operating Voltage":"12 TO 24 VDC","Manufacturer Brand":"Square D Co.","Product Description":"Telemecanique XU2S18PP340D 18Mm Photo 24Vdc","Additional Information":"APPROVAL UL, CSA, CE; BEAM TYPE INFRARED; OUTPUT CONFIGURATION PNP; SWITCHING FREQUENCY 500 HZ; LENS MATERIAL PMMA","Full Technical Description":"Nickel Plated Brass Material; XU2 Series Thru Beam Photoelectric Sensor Used on; M12 4 Pin DC Micro Male Connector Connection Type; 12 to 24 VDC Operating Voltage; IP67 Enclosure; Threaded Construction; 8 M Sensing Distance; 1 Millisecond Response Time; Light/Dark Operating Mode; PREVENTA[T] Brand; Approval UL, CSA, CE; Beam Type Infrared; Output Configuration PNP; Switching Frequency 500 Hz; Lens Material Pmma; XU2 Model","Proposition 65 Warning (CA)":"WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$100.33 – $171.09","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/648953587c8c5f42ad41032f9dd21425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second source for XU2S18PP340D?","answer":"XU2S18PP340WD is the closest functional alternative in the same XU2 thru-beam family: 8 m range, 12 to 24 VDC, PNP, M12 4-pin DC micro, 500 Hz / 1 ms response — the difference is a 90 deg side sensing head versus the axial head on XU2S18PP340D."},{"question":"Will XU2S18PP340D drop into a panel specified around XU2S18PP340WD without rewiring?","answer":"On the electrical side yes — both share 12 to 24 VDC, PNP, M12 4-pin DC micro, 8 m, 500 Hz, 1 ms; the only documented difference is a 90 deg side sensing head on the WD versus the axial head on the D, so verify the bracket geometry before signing off the swap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/XU2S18PP340D","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/XU2S18PP340D when reusing this data.
