The Sick WTS26P-34161120A00 (part no. 1218949) is a high-performance diffuse photoelectric sensor with extended background-suppression capabilities, designed to provide reliable and precise object detection in industrial automation applications. With a sensing range from 10 mm to 1,000 mm, it is ideal for medium- to long-distance detection tasks, such as conveyor monitoring, packaging, automated assembly, and material handling. The sensor’s visible red LED produces a focused light spot, enabling accurate and stable detection even on reflective, irregular, or challenging surfaces.

Configuration and setup are simplified with the BluePilot Teach-Turn adjustment system, which allows operators to quickly set the sensing range via a tactile dial. Visual LED feedback confirms the selected settings, minimizing setup errors and reducing commissioning time. For smart automation systems, the WTS26P-34161120A00 supports IO-Link v1.1, which provides remote configuration, real-time diagnostics, and access to Smart Task functionality including timers, logic operations, and window monitoring. This allows the sensor to operate not only as a detector but also as an intelligent component in automated processes.

The sensor is equipped with dual push-pull outputs, compatible with both PNP and NPN control systems. It achieves a response time of ≤ 500 µs and a switching frequency of up to 1,000 Hz, enabling high-speed performance in processes such as sorting, packaging, and conveyor control. Built-in protections against short circuits, reverse polarity, and overload ensure stable and safe operation in industrial environments.

Physically, the WTS26P-34161120A00 is housed in a robust VISTAL® enclosure measuring 26 × 80 × 60 mm. Its IP66, IP67, and IP69 ratings provide protection against dust, water, and high-pressure washdowns, allowing reliable operation in harsh industrial conditions. The sensor operates over a wide temperature range (–40 °C to +60 °C) and features a long LED lifetime of approximately 100,000 hours. Integrated Smart Sensor diagnostics support predictive maintenance, enabling operators to monitor signal quality and device health proactively, reducing unplanned downtime and improving overall system efficiency.

In summary, the Sick WTS26P-34161120A00 combines extended background-suppression detection, fast and intuitive setup, high-speed dual outputs, and rugged construction. It is an ideal solution for modern industrial automation applications requiring reliable, intelligent, and high-performance object detection.
