It needs a reflector mounted opposite — the sensor and reflector are a pair, so if you're replacing a through-beam or proximity unit, the mounting and wiring change. The 500 µs response time is fast enough for counting small parts on a conveyor or detecting objects at line speed, but not for high-speed ejection or singulation. The IP66, IP67, and IP69 ratings mean this sensor handles washdown environments — think food processing, beverage lines, or any area where hot water and chemical cleaners hit the housing. The IP69 rating specifically covers high-pressure, high-temperature spray, so it survives the sanitation cycles that kill lesser sensors out here in the grease. The output is configurable as push-pull, PNP, or NPN, which gives flexibility to match whatever PLC input card or relay interface you already have on the panel. Light-ON or Dark-ON switching is selectable via the teach-in or wiring — no extra adapter needed. ## Mounting and wiring reality The M12 male connector (4-pin) means you pre-wire a female cordset, not hard-wire into the housing. If your existing line uses pigtail sensors with flying leads, you'll need an M12 cordset or an adapter. Operating voltage range is 10 to 30 VDC, so it runs on standard 24 VDC control power without a separate supply. The load current is 50 mA — well within the capacity of most PLC outputs or relay coils.","metaTitle":"SICK WLA26P-P03 Retro-Reflective Sensor, 12 m, IP69","metaDescription":"SICK WLA26P-P03 photoelectric retro-reflective sensor, 12 m range, 500 µs response, IP66/IP67/IP69, M12 connector.

This is a retro-reflective sensor, so you must mount a reflector opposite the sensor. The exact reflector model depends on the target size and mounting distance — SICK recommends a PL80A or similar for maximum range."},{"question":"Will the WLA26P-P03 drop into a panel wired for the WTB26P-24161120A00Z?","answer":"Not without rewiring. The WTB26P-24161120A00Z is a proximity sensor with a 1.6 m range and a different mounting orientation (53 mm wide vs 25 mm). The WLA26P-P03 is a retro-reflective sensor requiring a reflector, and its M12 pinout may differ. Check the wiring diagram before swapping."},{"question":"What are the key ratings for the WLA26P-P03?","answer":"12 m sensing distance, 500 µs response time, 10–30 VDC supply, 50 mA load, IP66/IP67/IP69 protection, visible red LED, push-pull/PNP/NPN output, M12 connector."},{"question":"What compliance documentation is available for the WLA26P-P03?","answer":"Standard SICK documentation includes a datasheet and operating instructions. The sensor carries CE, UL, and CSA approvals typical for the W26 series.
