The SICK WL4S-3E1330V (Part No. 1046420) is a high-performance photoelectric proximity sensor designed for precise and dependable object detection in industrial automation applications. Featuring background suppression technology and a focused PinPoint red LED, the sensor ensures accurate detection of objects while minimizing interference from reflections, uneven surfaces, or complex backgrounds. This guarantees consistent and repeatable performance in high-speed production lines, robotic workstations, and automated packaging systems.

A major feature of the WL4S-3E1330V 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-constrained areas or high-density sensor arrays, including conveyor systems, robotic stations, and automated packaging machinery. Despite its small size, the sensor is engineered for industrial durability, ensuring long-term reliability and consistent performance in challenging operational conditions.

The sensor incorporates 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 up to 1 kHz, the WL4S-3E1330V is capable of managing high-speed automation tasks effectively. Typical applications include object detection, sorting, counting, and robotic positioning, where rapid and precise detection is critical for maintaining productivity and process accuracy.

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

The WL4S-3E1330V projects a narrow 2.5 mm light spot at 50 mm distance, enabling 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-3E1330V combines compact design, fast response, precise detection, and rugged industrial durability. It is ideal for logistics, packaging, robotics, and manufacturing industries, delivering reliable object detection in high-speed and demanding operational environments.
