Sick VL180-2P42433 Photoelectric Sensor

The VL180-2P42433 Photoelectric Sensor from Sick is a powerful photoelectric retro-reflective sensor engineered for high-reliability object detection at ranges up to 5.5 meters. With its dual lens system and a visible red LED light source (645 nm wavelength), it delivers a focused beam with a spot size of Ø 270 mm at 4 m. This ensures accurate detection of objects across long distances, even in dusty or variable lighting conditions. The cylindrical housing (84.2 mm in length) is made of nickel-plated brass and polycarbonate (PC), offering excellent durability and protection in rugged automation environments.

The VL180-2P42433 supports both light and dark switching modes, with a selectable mode using the L/D control cable, providing flexibility for integration in different systems. With a rapid response time of ≤ 0.5 ms and a switching frequency of 1,000 Hz, it is suitable for high-speed automation tasks such as conveyor belt monitoring or packaging line presence detection. It operates on a wide supply voltage range of 10 V DC to 30 V DC and draws only 30 mA, making it energy-efficient and cost-effective. The sensor includes a M12, 4-pin male connector for quick plug-and-play wiring, while the IP67 enclosure rating ensures long-lasting performance in industrial conditions.

The VL180-2P42433 Photoelectric Sensor is widely used in Indian industrial automation setups, especially where long-range object detection is needed in tight spaces. Its retro-reflective design makes it ideal for detecting transparent bottles, cartons, or metallic objects on fast-moving production lines without requiring complicated calibration.

Maintenance engineers find this photoelectric sensor easy to install and align, thanks to its bright red beam and built-in sensitivity adjustment via the 270° potentiometer. It performs reliably in applications such as material handling, packaging, and textile machinery, where variable ambient light and vibrations are common. The sensor’s metal housing and sealed IP67 construction also make it suitable for environments with exposure to dust, moisture, or mechanical stress.

For engineering students and automation trainees, the Sick VL180-2P42433 Photoelectric Sensor offers a practical example of advanced optoelectronic sensing that combines speed, precision, and robustness. With its high switching frequency and adjustable sensitivity, it shows how modern sensors enable reliable detection in real-world conditions. If you're building or upgrading industrial systems, this photoelectric sensor provides both performance and longevity you can count on.
