The SICK WL4S-3P3430V (Part No. 1046415) is a high-performance photoelectric proximity sensor designed for precise and dependable object detection in industrial automation applications. Featuring background suppression technology paired with a focused PinPoint red LED, the sensor ensures accurate detection of objects while minimizing interference from reflections, irregular surfaces, or complex backgrounds. This guarantees stable, repeatable performance in fast-moving production lines, robotic workstations, and automated packaging systems.

A notable advantage of the WL4S-3P3430V 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 integration into space-constrained installations or high-density sensor arrays, such as 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 performance in demanding operational environments.

The sensor features a PNP switching output with complementary light/dark switching, offering flexibility for 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-3P3430V can efficiently manage high-speed automation tasks. Applications include object detection, sorting, counting, and robotic positioning, where rapid and precise detection is essential for maintaining productivity and process accuracy.

Built for industrial durability, 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 excellent resistance to dust, dirt, and water, making it suitable for washdown-prone or harsh industrial environments. Additionally, the sensor functions reliably across a temperature range from –40 °C to +60 °C, supporting operation in both cold storage and high-temperature production areas.

The WL4S-3P3430V emits 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-3P3430V combines compact design, rapid response, precise detection, and rugged industrial durability. It is ideal for industries such as logistics, packaging, robotics, and manufacturing, providing reliable object detection in high-speed and demanding operational environments.
