The SICK WT24-2B440T01 (Part No. 1017911) is a photoelectric proximity sensor engineered to deliver reliable detection and long service life in industrial automation. Part of the well-proven WT24-2 series, this model is built to handle tough conditions while maintaining high precision in object recognition.

At the heart of the sensor is a visible red LED light source combined with background suppression technology. This configuration enables the WT24-2B440T01 to reliably detect objects within a working range of 50 mm to 1,000 mm, regardless of background conditions. By distinguishing the foreground object from its surroundings, the sensor ensures accurate switching even when reflective or textured surfaces are present in the background. This makes it ideal for conveyor systems, packaging lines, and material handling tasks where object positioning must be highly reliable.

The unit’s output flexibility further enhances its usefulness. The sensor features a PNP transistor output with the ability to switch in either light-ON or dark-ON modes, depending on the control system’s requirements. This adaptability makes integration into existing machinery straightforward, reducing setup complexity and ensuring compatibility with a wide range of controllers and PLCs.

Durability and ruggedness are key strengths of the WT24-2B440T01. Encased in a robust housing with an IP67 and IP69K protection rating, the device is shielded against dust, water, and even high-pressure washdowns. This ensures reliable operation in environments such as food and beverage processing, automotive manufacturing, and logistics centers, where exposure to contaminants and cleaning agents is common.

For ease of installation and maintenance, the sensor is equipped with a standard M12, 4-pin male connector, a widely used industrial connection format. This simplifies wiring, ensures secure connectivity, and allows fast replacement if required. The compact housing also makes it suitable for mounting in areas where space is limited, while still delivering high sensing performance.

Performance characteristics include a rapid response time that enables the detection of fast-moving objects, ensuring the sensor keeps pace with high-speed automation processes. The unit’s consistent switching behavior reduces false triggers, minimizing downtime and maintaining production efficiency.

The WT24-2B440T01 is also designed for straightforward configuration. Using the built-in adjustment mechanism, operators can fine-tune the detection threshold to match specific application conditions, such as varying object sizes, materials, or colors. This allows the sensor to adapt seamlessly to changing requirements without extensive reprogramming or replacement.

In summary, the SICK WT24-2B440T01 is a versatile and durable sensor that combines long-range detection, flexible output modes, and rugged housing protection. It is ideally suited for industrial environments that demand precision, robustness, and easy integration, making it an excellent choice for engineers and integrators seeking dependable object detection in challenging conditions.
