The SICK WTB4S-3P3435V (Part No. 1046407) is a high-performance photoelectric proximity sensor engineered for precise and dependable object detection in industrial automation applications. Utilizing background suppression technology combined with a focused PinPoint red LED, the sensor ensures accurate detection of objects while filtering out reflections and variations from complex background surfaces. This guarantees stable, repeatable performance in fast-moving production lines, packaging systems, and robotic automation setups.

A primary advantage of the WTB4S-3P3435V is its compact rectangular housing, measuring 12.2 mm √ó 41.8 mm √ó 17.3 mm and weighing approximately 30 g. Its slim, lightweight design allows installation in space-constrained areas or high-density sensor arrays, including conveyor lines, robotic workstations, and automated packaging machinery. Despite its small footprint, the sensor is built for industrial durability, offering long-term reliability even in demanding operational environments.

The sensor features a PNP switching output with complementary light/dark switching, providing 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 WTB4S-3P3435V is capable of managing high-speed automation tasks efficiently. Applications include object detection, sorting, counting, and robotic positioning, where precise and rapid detection is essential for maintaining productivity and process accuracy.

Engineered for harsh industrial conditions, 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 ingress, making it suitable for challenging industrial environments or washdown-prone applications. Additionally, it functions reliably across a temperature range of –40 °C to +60 °C, supporting operation in both cold storage areas and high-temperature production zones.

The WTB4S-3P3435V emits a narrow 2.5 mm light spot at 50 mm distance, enabling precise detection of small or thin objects. The integrated LED has an estimated service life of approximately 100,000 hours under normal operating conditions, reducing maintenance requirements and maximizing uptime.

In summary, the WTB4S-3P3435V combines compact size, fast response, accurate detection, and rugged industrial construction. It is ideal for logistics, packaging, robotics, and manufacturing industries, providing reliable object detection in high-speed and demanding operational environments.
