The Sick WLA26P-1H162100A00 (part no. 1218822) is a high-performance photoelectric sensor designed for long-range detection in industrial automation and process control applications. It is part of the WLA series, engineered to deliver reliable, precise object detection over extended distances. The sensor’s sensing range of 0.1 m to 20 m makes it ideal for applications requiring detection of objects over medium to long distances, including material handling, conveyor monitoring, and outdoor automation. Its high-intensity visible red LED ensures accurate detection with strong optical contrast, enabling reliable operation even in challenging lighting or background conditions.

Setup is made simple through the BluePilot Teach-Turn adjustment system, which allows operators to configure the sensing range manually using a tactile dial. The integrated visual LED feedback provides immediate confirmation of settings, reducing setup time and minimizing the potential for misalignment. For more advanced control and monitoring, the sensor supports IO-Link v1.1, providing remote configuration, diagnostic feedback, and access to Smart Task functions such as logic operations, timers, and window monitoring. This integration allows the WLA26P to function as a smart, connected sensor within modern automated systems.

The sensor offers dual push-pull outputs, compatible with both PNP and NPN systems. It delivers response times of ≤ 1 ms and switching frequencies up to 500 Hz, allowing it to operate effectively in fast-moving processes and high-speed production lines. Built-in electrical protections ensure stable operation under harsh industrial conditions, safeguarding against reverse polarity, short circuits, and overloads.

Physically, the WLA26P-1H162100A00 is housed in a robust aluminum enclosure, providing resistance against dust, moisture, and mechanical impact. Rated IP67, it can withstand challenging environments, including washdown or outdoor conditions. The sensor operates reliably across a wide temperature range, making it versatile for various industrial settings. Its long operational life and high reliability ensure minimal maintenance requirements, and integrated Smart Sensor diagnostics allow predictive maintenance planning to reduce unplanned downtime.

In summary, the Sick WLA26P-1H162100A00 combines ultra-long-range red LED detection, intuitive setup, robust construction, and smart connectivity. It is an ideal solution for industrial applications requiring precise long-distance sensing, reliable operation under demanding conditions, and integration into connected automation systems.
