The Sick WLG16P-34162120A00 (part no. 1218947) is a high-performance diffuse photoelectric sensor with background-suppression technology, designed to deliver reliable and precise object detection in industrial automation environments. With a sensing range of 10 mm to 800 mm, it is ideal for short- to medium-distance detection tasks, including conveyor monitoring, packaging, material handling, and automated assembly operations. Its visible red LED provides a sharply focused light spot, ensuring stable detection even on reflective, uneven, or complex surfaces.

The sensor features BluePilot Teach-Turn adjustment, allowing operators to quickly configure the sensing range using a tactile dial. Visual LED feedback confirms the settings in real time, minimizing setup errors and reducing commissioning time. For smart automation environments, the WLG16P-34162120A00 supports IO-Link v1.1, enabling remote configuration, monitoring, and Smart Task functions such as logic operations, timers, and window monitoring. This makes the sensor a versatile and intelligent component for modern automated systems.

Equipped with dual push-pull outputs, the sensor is compatible with both PNP and NPN systems. It achieves a response time of ≤ 500 µs and a switching frequency up to 1,000 Hz, making it suitable for high-speed applications such as sorting, packaging, and conveyor control. Built-in protections against short circuits, overload, and reverse polarity ensure safe and stable operation in demanding industrial conditions.

Physically, the WLG16P-34162120A00 is housed in a rugged VISTAL® enclosure measuring 16 × 55 × 42 mm. With IP66, IP67, and IP69 ratings, it is resistant to dust, water, and high-pressure washdowns, ensuring reliable operation even in harsh industrial environments. The sensor functions across a wide temperature range (–40 °C to +60 °C) and features a long LED service life of approximately 100,000 hours. Integrated Smart Sensor diagnostics support predictive maintenance, allowing operators to monitor signal quality and device health proactively, reducing unplanned downtime and enhancing system efficiency.

In summary, the Sick WLG16P-34162120A00 combines precise background-suppression detection, intuitive setup, high-speed switching, and rugged housing. It is an ideal solution for industrial applications requiring reliable, intelligent, and high-performance object detection in automated environments.
