Sick VL180-2F32331 Photoelectric Sensor

The Sick VL180-2F32331 Photoelectric Sensor is a dual-lens retro-reflective sensor built for performance, durability, and precision in factory automation. Engineered with a cylindrical M18 x 1 threaded housing and a robust metal body of nickel-plated brass, this sensor is made to withstand rugged industrial environments while delivering consistent and accurate detection. With dimensions of 18 mm x 18 mm x 70.2 mm, it easily fits into compact spaces and integrates with standard mounting systems used in automated machinery.

This sensor offers an extended sensing range of 0.05 m to 6 m with a maximum range of 7 m, making it suitable for long-distance detection tasks using a visible red LED light source at 645 nm wavelength. The dual-lens optical system ensures reliable signal strength and improved background suppression, while the focused light beam with a 4.5° angle of dispersion and a 400 mm spot diameter at 6 m helps minimize false readings caused by nearby reflective surfaces.

With a supply voltage of 10 V DC to 30 V DC and low current consumption of 30 mA, the VL180-2F32331 is energy-efficient and easy to power within typical PLC and control panel configurations. The PNP output and light switching mode provide compatibility with digital control systems. It features a fast response time of ≤ 0.5 ms and a switching frequency of 1,000 Hz, making it a dependable choice for high-speed applications. With a rugged IP67-rated enclosure and a standard M12 4-pin male connector, this model ensures both environmental protection and quick installation. Explore more on the official Sick website.

The Sick WL4S-3F2130 Photoelectric Sensor is widely used in conveyor systems, automated packaging lines, and robotic applications that require fast and reliable object detection. Its precision and compact build make it ideal for detecting boxes, bottles, parts, or pallets moving at high speeds across sensors on factory floors.

Junior maintenance engineers benefit from its easy plug-and-play setup using the M12 connector and clear visible red light for alignment. It reduces troubleshooting time thanks to its stable sensing performance even in environments with dust, vibrations, or reflective backgrounds. For senior plant engineers, the sensor delivers operational confidence with minimal maintenance due to its IP67 enclosure and long service life.

For engineering students and automation trainees, this model serves as a hands-on example of how dual-lens optics, retro-reflective sensing, and light/dark switching logic come together in modern industrial automation. They can observe how reliable sensors improve the efficiency and accuracy of automated systems. In short, Sick sensors like the WL4S-3F2130 empower teams to build smarter, safer, and more responsive machines—backed by proven German engineering.
