It uses a red LED light source and outputs a switching signal in PNP, NPN, or Push-Pull format, selectable via wiring. The 500 µs response time keeps up with fast-moving targets on a conveyor or pick-and-place station. IP69 protection means the sensor withstands high-pressure, high-temperature washdown cycles common in food-and-beverage, tire manufacturing, and heavy washdown environments. The M12 4-pin connector simplifies field replacement — no hardwiring into the sensor head. The 1.6 m sensing distance is the maximum range for a white 90% reflective target. For dark or matte objects, expect that range to shrink — background suppression works by triangulation, so a black target at 1.6 m may not trigger reliably. The minimum sensing distance of 30 mm means the sensor can detect objects very close to the lens face, useful for tight clearance applications. Light-ON / Dark-ON switching is selected by wiring the output accordingly — no DIP switch or software config needed. The 100 mA load current drives a PLC input or small relay directly, but check the total loop draw if powering multiple sensors from one supply. Operating voltage range is 10–30 VDC. Temperature range is -40 to +60 °C. ## Where to use this class of sensor Mounting footprint is 25 mm wide × 53 mm tall × 83 mm deep — standard W26 form factor. If replacing an older W26 sensor, the same bracket and gland plate hole pattern fits. The M12 connector orientation is axial (straight out the back), so leave clearance for the mating cordset.","metaTitle":"SICK WTB26P-24161120A00Z Photoelectric Proximity Sensor, 1.6","metaDescription":"SICK WTB26P-24161120A00Z W26 photoelectric proximity sensor, 1.6m range, 500 µs response, PNP/NPN/Push-Pull output, IP69, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Photoelectric Sensors"],"specifications":{"Width":"25 mm","Height":"53 mm","Length":"83 mm","Series":"W26","Light Type":"LED, Red","Sensor Type":"Photoelectric Proximity Sensor","Load Current":"100 mA","Response Time":"500 us","Switching Type":"Light-ON / Dark-ON","lifecycle_stage":"current","Termination Type":"Connector, M12, 4-Pin","Protection Rating":"IP69","Sensing Distance Max.":"1.6 m","Sensing Distance Min.":"30 mm","Operating Voltage Max.":"30 VDC","Operating Voltage Min.":"10 VDC","Operating Temperature Max.":"60 °C","Operating Temperature Min.":"-40 °C","Optical Sensor Output Type":"PNP;NPN;Push-Pull"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$273.10","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d95439bbf595537ac3d34062ed9794f3.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/WTB26P-24161120A00Z/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative — WLA26P-P03?","answer":"The WLA26P-P03 is a retro-reflective sensor (requires reflector, range 12 m), not a background-suppression proximity sensor. It shares the W26 mounting footprint and M12 connector but detects differently. For a direct drop-in replacement with the same detection principle, stay with the WTB26P series.

Electrically yes — both run 10–30 VDC with PNP/NPN/Push-Pull output. But the WLA26P-P03 is retro-reflective (requires reflector), while this is background-suppression proximity.
