SICK WT18-N112 Photoelectric Proximity Sensor

The SICK WT18-N112 Photoelectric Proximity Sensor is a compact, rectangular optical switch from SICK’s WT18 family designed for non-contact detection on production lines. The housing measures 17 mm in width, 75 mm in height, and 32.5 mm in depth, enabling mounting in tight spaces on conveyors, packaging equipment, and automated machinery. As a photoelectric proximity sensor, it detects the presence or absence of objects using light without physical contact, making it suitable for small parts and features where contact sensors are impractical. The WT18-N112 variant is part of SICK’s widely used WT18 line, known for reliable operation in industrial environments and straightforward integration with common controllers. For installation, alignment and wiring should follow SICK’s guidelines to ensure proper sensing and safe operation in your specific application.
