The Sick WTL16P-34161120A00 (part no. 1218945) is a high-performance diffuse photoelectric sensor with background-suppression technology, designed to provide reliable and precise object detection in modern industrial automation applications. With a sensing range from 10 mm to 800 mm, the sensor is well-suited for short- to medium-distance tasks, including conveyor monitoring, packaging, material handling, and automated assembly processes. Its red LED emits a sharply focused beam, enabling stable detection even when surfaces are reflective, irregular, or complex.

Setup and configuration are made simple with the BluePilot Teach-Turn adjustment system, which allows operators to set the sensing range quickly using a tactile dial. The sensor provides immediate visual feedback via an LED indicator, reducing setup time and minimizing potential misalignment or configuration errors. For advanced automation environments, the WTL16P-34161120A00 supports IO-Link v1.1, allowing remote configuration, diagnostic monitoring, and access to Smart Task functions such as timers, logic operations, and window monitoring. This integration makes the sensor not only a detector but also an intelligent component in automated systems.

The sensor’s dual push-pull outputs are compatible with both PNP and NPN systems, providing a response time of ≤ 500 µs and a switching frequency up to 1,000 Hz, enabling fast and reliable operation in high-speed applications such as sorting, packaging, and conveyor control. Built-in electrical protections against reverse polarity, overload, and short circuits ensure safe and stable operation in demanding industrial environments.

Physically, the WTL16P-34161120A00 is housed in a rugged VISTAL® enclosure measuring 16 × 55 × 42 mm. Its IP66, IP67, and IP69 ratings provide resistance to dust, water, and high-pressure washdowns, allowing reliable performance in harsh industrial conditions. The sensor operates across a wide temperature range (–40 °C to +60 °C) and features a long LED lifetime of approximately 100,000 hours. With integrated Smart Sensor diagnostics, predictive maintenance is supported, allowing operators to monitor device health and signal quality proactively, reducing unplanned downtime and improving overall system efficiency.

In summary, the Sick WTL16P-34161120A00 combines precise background-suppression detection, intuitive setup, high-speed switching, and rugged design. It is an ideal solution for industrial applications requiring reliable, intelligent, and high-performance object detection in modern automated environments.
