The Sick WLA26P-34162100A00 (part no. 1218823) is a high-performance photoelectric sensor from the WLA series, designed for ultra-long-range object detection in industrial automation and process control applications. It provides a sensing range from 0.1 m up to 20 m, making it suitable for applications that require detection over medium to long distances, such as conveyor monitoring, material handling, and automated outdoor processes. The sensor’s highly visible red LED produces a focused beam that ensures accurate detection and strong optical contrast, delivering reliable performance even in environments with complex or reflective backgrounds.

The sensor is equipped with BluePilot Teach-Turn adjustment, which allows operators to quickly set the sensing range using a tactile dial. Visual LED feedback provides immediate confirmation, simplifying setup and reducing the risk of misalignment. For advanced automation systems, the sensor includes IO-Link v1.1, which enables remote configuration, parameter replication, and real-time diagnostic monitoring. Smart Task functionality, such as timers, logic operations, and window monitoring, can be implemented directly within the sensor, enhancing system intelligence and reducing the need for external controllers.

Performance is further enhanced with dual push-pull outputs, supporting both PNP and NPN configurations. The sensor provides a response time of ≤ 1 ms and a switching frequency up to 500 Hz, enabling it to operate effectively in high-speed processes. Electrical protections, including safeguards against short circuits, reverse polarity, and overload, ensure stable and safe operation in demanding industrial environments.

The WLA26P-34162100A00 is housed in a robust aluminum casing with IP67 protection, providing resistance to dust, water, and mechanical stress. This rugged design allows the sensor to perform reliably in harsh industrial conditions, including washdown areas and outdoor applications. With a long operational lifetime and integrated Smart Sensor diagnostics, the sensor supports predictive maintenance, helping to reduce unplanned downtime and increase system efficiency.

In summary, the Sick WLA26P-34162100A00 combines ultra-long-range red LED detection, fast and intuitive setup, high-speed switching, and rugged industrial housing. Its advanced IO-Link connectivity and Smart Sensor capabilities make it a future-ready solution for demanding automation applications requiring precise, reliable, and intelligent object detection.
