Description
The SICK WT170-N410 is a photoelectric proximity sensor with background suppression designed for precise short-range object detection in industrial automation. Using visible red LED technology, it reliably detects targets within a 10–100 mm range while minimizing interference from background surfaces. This model is discontinued by the manufacturer but remains suitable for legacy system support and replacement needs.
