Sick VTE180-2P42487 Photoelectric Sensor

The Sick VTE180-2P42487 Photoelectric Sensor is a high-performance photoelectric proximity sensor designed for demanding applications where long-range detection and compact form factor are critical. With a precise sensing range of 1 mm to 800 mm and a maximum range of up to 1,100 mm, it utilizes a visible red LED light source at 645 nm wavelength to ensure sharp, consistent detection across different target types and surface colors.

Built with a cylindrical 18 mm x 18 mm housing and an axial light emission design, the sensor is ideal for installations in narrow mechanical assemblies. The light spot diameter of Ø 30 mm at 800 mm and a narrow 1.2° angle of dispersion help maintain high accuracy in object alignment, even in areas with background reflectivity. Its M18 threaded housing and M12 4-pin male connector enable quick and secure integration into automation panels and field devices.

This sensor supports PNP output with light/dark switching, selectable via control wire, offering versatility in logic control systems. It operates on a standard 10 V DC to 30 V DC power supply with a low current draw of 30 mA. The device delivers a fast response time of ≤ 0.5 ms and an outstanding switching frequency of 1,000 Hz, allowing real-time response in automated sorting, packaging, or inspection systems. With its IP67-rated plastic housing made of PBT/PC and PMMA optics, the VTE180-2P42487 is resistant to dust, moisture, and industrial wear — making it a reliable choice for long-term deployment in Indian manufacturing plants.

The Sick WL4S-3F2130 Photoelectric Sensor is commonly used in industrial conveyor systems, automated assembly lines, and warehouse sorting applications. Its compact body and accurate detection capabilities make it ideal for identifying small components, transparent items, and reflective packaging on high-speed belts.

In an Indian factory scenario—where inconsistent lighting, dust, or background reflections often disrupt detection—the WL4S-3F2130 ensures stable sensing with minimal false triggers. Junior maintenance engineers appreciate how easily the sensor can be aligned using its visible red light, while senior technicians value its low-maintenance operation and robust output performance even in fluctuating power conditions. This reduces production delays and troubleshooting time, contributing to higher uptime.

For engineering students and automation trainees, the WL4S-3F2130 provides a hands-on learning opportunity. It illustrates principles like background suppression, light-dark switching logic, and beam focusing—helping them connect theoretical knowledge with real-world applications. Whether used in FMCG packaging, material handling, or robotics, Sick photoelectric sensors empower engineers to build smart, dependable systems with precision and repeatability.
