The SICK WL4S-3N1130V (Part No. 1046418) is a high-performance photoelectric proximity sensor engineered for precise and dependable object detection in demanding industrial automation environments. Utilizing background suppression technology together with a focused PinPoint red LED, the sensor ensures accurate detection of objects while minimizing interference from reflective surfaces, irregular backgrounds, or complex environments. This enables consistent, repeatable performance in high-speed production lines, robotic workstations, and automated packaging applications.

A key feature of the WL4S-3N1130V 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 easy installation in space-limited areas or high-density sensor arrays, such as conveyor lines, robotic stations, and automated packaging machinery. Despite its small size, the sensor is built for industrial durability, ensuring long-term reliability and consistent performance in challenging operational conditions.

The sensor features a PNP switching output with complementary light/dark switching, providing flexibility for integration with a wide range of control systems. With a response time under 0.5 ms and a switching frequency of up to 1 kHz, the WL4S-3N1130V can efficiently manage high-speed automation tasks. Typical 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 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 exposure, making it suitable for washdown-prone or demanding industrial conditions. Additionally, it functions reliably across a temperature range from –40 °C to +60 °C, supporting use in both cold storage facilities and high-temperature production zones.

The WL4S-3N1130V projects a narrow 2.5 mm light spot at 50 mm distance, allowing precise detection of small or thin objects. Its integrated LED has a service life of approximately 100,000 hours under normal operating conditions, reducing maintenance requirements and maximizing operational uptime.

In summary, the WL4S-3N1130V 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.
