The SICK WL4S-3F1330V (Part No. 1046417) is a high-performance photoelectric proximity sensor designed for precise and reliable object detection in industrial automation environments. Utilizing background suppression technology and a focused PinPoint red LED, the sensor ensures accurate detection of objects while minimizing interference from reflections, uneven surfaces, and complex backgrounds. This allows consistent, repeatable performance in high-speed production lines, robotic workstations, and automated packaging systems.

A key feature of the WL4S-3F1330V is its compact rectangular housing, measuring 12.2 mm √ó 41.8 mm √ó 17.3 mm and weighing approximately 30 g. Its slim and lightweight design allows installation in space-limited areas or high-density sensor arrays, including conveyor systems, robotic stations, and automated packaging machinery. Despite its small footprint, the sensor is engineered for industrial durability, ensuring long-term reliability and consistent operational performance in demanding environments.

The sensor includes a PNP switching output with complementary light/dark switching, offering flexible integration with a variety of control systems. With a response time under 0.5 ms and a switching frequency of up to 1 kHz, the WL4S-3F1330V is capable of handling high-speed automation tasks effectively. Applications include object detection, sorting, counting, and robotic positioning, where rapid and precise detection is critical for maintaining productivity and process accuracy.

Designed for harsh industrial conditions, the sensor operates on a 10–30 V DC supply and incorporates protection against reverse polarity, short circuits, and electrical interference. Its IP66/IP67-rated housing provides strong resistance to dust, dirt, and water exposure, making it suitable for challenging or washdown-prone environments. Additionally, it functions reliably across a temperature range from –40 °C to +60 °C, supporting operation in both cold storage and high-temperature production zones.

The WL4S-3F1330V emits a narrow 2.5 mm light spot at 50 mm distance, allowing precise detection of small or thin objects. Its integrated LED has an estimated service life of approximately 100,000 hours under normal operating conditions, minimizing maintenance needs and maximizing operational uptime.

In summary, the WL4S-3F1330V combines compact design, rapid response, precise detection, and rugged industrial durability. It is ideal for logistics, packaging, robotics, and manufacturing industries, providing reliable object detection in high-speed and demanding operational environments.
