Polarised retro-reflection, 18 m range
The SICK WLA26P-24162100A00 is a polarised retro-reflection photoelectric sensor in a block housing, rated for a detection range of 0 to 18 m. The polarised optics reject reflections from shiny targets — the sensor triggers only on the retroreflector return, so it won't false-trigger on a glossy package or a polished shuttle surface. That 18 m range covers a full aisle in a high-bay AS/RS or a long conveyor zone with one reflector at the far end.
The WLA26P-24162100A00 carries a current lifecycle stage from SICK.
