WLA26P-24162100A00 Retro-reflective Sensor 18m Push-Pull IP69K | SICK

The Original New SICK WLA26P-24162100A00 (1218664) is a high-performance photoelectric retro-reflective sensor from the W26 series, designed for reliable object detection in demanding industrial environments. Its autocollimation optical system requires no minimum distance to the reflector, simplifying installation in space-constrained machinery. A visible red PinPoint LED (635 nm) delivers a precise Ø 100 mm light spot at 10 m, while the integrated polarising filter ensures stable detection of reflective or film-wrapped targets. Housed in an ultra-rugged VISTAL® plastic enclosure rated IP66/IP67/IP69K, the sensor withstands chemical, thermal, and mechanical stress. The push-pull (PNP/NPN) output and IO-Link communication with BluePilot alignment aid enable flexible integration and fast commissioning.
