The SICK VTF18-4N5240 is a precision-engineered photoelectric proximity sensor crafted for dependable object detection in demanding industrial environments. Encased in a compact M18 cylindrical housing, the sensor is ideal for tight-space installations across automated assembly lines, conveyor systems, packaging machinery, and more.

Utilizing diffuse sensing technology enhanced with background suppression, the VTF18-4N5240 can reliably detect objects from 0 mm up to around 50 mm—even against challenging or reflective surfaces. This capability significantly minimizes false triggers, enhancing accuracy and reliability in fast-moving production scenarios.

Designed for adaptability, the sensor includes an NPN open-collector output that supports both light-on and dark-on switching modes. This user-selectable configuration streamlines the integration process, allowing seamless compatibility with various control systems, including PLCs and relay-based logic, without the need for complex wiring modifications or additional components.

The VTF18-4N5240 excels in durability. Its IP67-rated enclosure offers robust protection against dust and temporary immersion in water—ideal for environments where moisture, debris, or residue may be present. Complementing this, the sensor maintains stable operation across a wide temperature spectrum from –25 °C to +70 °C, making it reliable in both cold-chain facilities and high-temperature manufacturing zones.

Ease of configuration further boosts its appeal. A built-in 270° potentiometer allows for fine-tuned adjustment of the sensing distance, enabling precise calibration for varied object sizes and detection distances. This intuitive adjustment capability accelerates setup and makes maintenance straightforward on the factory floor.

In summary, the SICK VTF18-4N5240 is a compact, durable, and precise photoelectric proximity sensor. With its blend of diffuse sensing with background suppression, flexible NPN output options, robust environmental protection, and wide operating temperature tolerance, this sensor is a dependable choice for industrial automation applications that demand consistent accuracy and resilience.
