SICK WLA16P-24162100A00 W16 Retro-reflective Photoelectric Sensor 10m Push‑pull IP66/67/69K

SICK WLA16P‑24162100A00 is a retro-reflective photoelectric sensor from the W16 series for long-range object detection up to 10 m (max. switching distance 0 m … 10 m). Uses a PinPoint LED (visible red light, λ = 635 nm) with autocollimation optics and integrated polarising filter. Application‑oriented LED indicators (BluePilot alignment aid, green power/IO‑Link status, yellow receive beam status) simplify installation and monitoring. The IP66/IP67/IP69K VISTAL® plastic housing suits washdown and hygienic environments.

Applications:

• Packaging machinery (film‑wrapped pallets, transparent films, bottles)

• Conveyor systems and material handling (object presence on automated lines)

• Logistics automation and parcel sorting
