The SICK WLA16P-34161100A00 (Part No. 1221729) is a high-performance photoelectric sensor engineered to deliver precise, fast, and reliable object detection in industrial automation systems. Part of the WLA16P series, this sensor combines advanced optical technology, user-friendly configuration, and a rugged design, making it suitable for applications such as packaging, material handling, robotics, and automated manufacturing processes.
At the core of the sensor is its high-precision background-suppression technology, which ensures stable detection even on challenging surfaces. It can reliably sense shiny metallic objects, dark components, or textured materials without false triggers, guaranteeing consistent and repeatable performance. This capability is particularly important in high-speed production lines where accuracy and reliability are critical to maintaining product quality and operational efficiency.
For easy and intuitive setup, the sensor features BluePilot adjustment, allowing operators to quickly set the sensing range using a simple rotary dial. In addition, IO-Link connectivity provides advanced functionality such as remote parameterization, detailed diagnostics, and access to smart functions including timing, logic, and predictive maintenance. This connectivity supports integration into Industry 4.0 production systems and enables real-time monitoring of sensor performance.
Detection precision is further enhanced by the PinPoint visible red LED light source, which produces a sharply focused spot for accurate alignment. This feature simplifies installation and ensures precise object detection, even in compact or complex machine setups. The LED also provides immediate visual feedback during calibration and operation, reducing setup time and improving operational reliability.
Mechanically, the WLA16P-34161100A00 is housed in a compact VISTAL® enclosure, offering high durability while remaining lightweight. Its IP66 and IP67 protection ratings provide resistance to dust, water jets, and temporary immersion, ensuring dependable performance in harsh industrial environments. The compact dimensions facilitate easy integration into conveyors, robotic systems, or other machinery.
Electrically, the sensor operates on 10–30 V DC and provides a push-pull output (PNP/NPN) capable of switching up to 100 mA. With a response time of ≤1.4 ms and a switching frequency of up to 350 Hz, it delivers fast and reliable performance for high-speed automation applications. Built-in protections against short circuits, reverse polarity, and electrical interference enhance operational safety and reliability.
In summary, the SICK WLA16P-34161100A00 is a precise, robust, and intelligent sensor solution. Its background-suppression technology, BluePilot setup, IO-Link connectivity, PinPoint LED, and rugged VISTAL® housing make it ideal for industrial automation applications that demand speed, accuracy, and consistent long-term performance.
