The SICK WT12-2N450 is a compact photoelectric proximity sensor engineered for precise object detection in demanding automation environments. With background suppression, it delivers reliable switching on heterogeneous or reflective surfaces, making it an excellent choice for conveyor systems, packaging lines, and general machine building.

Offering a sensing range of 80 to 800 mm (up to 1000 mm max), the device uses visible red LED light for quick alignment and features an NPN output with selectable light/dark switching for flexible control integration. A fast ≤330 µs response supports high throughput, while a 10 to 30 V DC supply and a robust M12 4‑pin connection simplify installation. The zinc die-cast metal housing and IP67 sealing withstand shocks, vibration, and washdown; the sensor operates from -40 to +60 °C, and sensitivity is easily set via potentiometer for optimal background suppression.

Whether for new designs or retrofit projects, the WT12-2N450 shortens commissioning and ensures long-term detection stability, and it is backed by a 1-year warranty to support your maintenance and procurement commitments.
