The SICK WL4S-3P2130V (Part No. 1046413) is a high-performance photoelectric proximity sensor engineered for precise and dependable object detection in industrial automation environments. Incorporating background suppression technology along with a focused PinPoint red LED, the sensor ensures accurate detection of objects while minimizing interference from reflections and irregularities in the background. This ensures consistent and repeatable performance in fast-moving production lines, robotic automation systems, and packaging applications.

A key feature of the WL4S-3P2130V 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 confined spaces or high-density sensor arrays, including conveyor lines, robotic workstations, and automated packaging machinery. Despite its small size, the sensor offers robust construction for long-term reliability and dependable industrial performance.

The sensor features a PNP switching output with complementary light/dark switching, allowing 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-3P2130V is capable of managing high-speed automation tasks effectively. Applications include object detection, sorting, counting, and robotic positioning, where precise and rapid detection is critical to maintaining operational efficiency.

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, making it suitable for washdown-prone or challenging industrial conditions. Additionally, it performs reliably across a temperature range from –40 °C to +60 °C, supporting operation in both cold storage facilities and high-temperature production areas.

The WL4S-3P2130V 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-3P2130V combines compact size, fast 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
