WLA16P-24162100A00 Retro-Reflective Sensor 10m Push-Pull IO-Link | SICK

The Original New SICK WLA16P-24162100A00 (1218660) is a photoelectric retro-reflective sensor from the W16 series, designed for reliable object detection using autocollimation and coaxial optics. It provides a maximum sensing range of 0 … 10 m with a PinPoint LED light source (visible red light, 635 nm), delivering a precise Ø 80 mm light spot at 5 m for straightforward alignment. The sensor features push-pull PNP/NPN outputs with complementary switching and IO-Link V1.1 communication for integration into modern control systems. An integrated BluePilot alignment aid simplifies setup. Housed in a rugged VISTAL® plastic enclosure rated IP66/IP67/IP69K, it is built for demanding industrial environments. Note: This is a special version with a factory-set 10 ms switch-off delay.
