Sick VTE180-2P42447 Photoelectric Sensor

The Sick VTE180-2P42447 Photoelectric Sensor is designed with a compact 18 mm x 18 mm x 69.8 mm body and an M18 x 1 threaded cylindrical housing, making it well-suited for tight industrial spaces. Utilizing an energetic sensing principle, it emits visible red LED light at 645 nm with a beam focused at 1.5°, achieving reliable detection over a wide sensing range of 1 mm to 350 mm and a maximum capability of 500 mm. The sensor delivers consistent accuracy with a light spot size of Ø 20 mm at 400 mm, enabling detection of various surface types, including low-reflectivity targets.

This PNP switching sensor operates efficiently within a 10 V to 30 V DC supply range and maintains low energy consumption at 30 mA. Switching performance is rapid with a ≤ 0.5 ms response time and a high 1,000 Hz switching frequency, making it ideal for high-speed production lines. The light/dark switching mode is user-selectable via an L/D control cable, offering flexibility in sensor behavior depending on detection needs. Users can fine-tune the sensing distance using the 270° potentiometer integrated on the sensor.

The VTE180-2P42447 is protected by an IP67-rated enclosure made from PBT/PC plastic for the housing and PMMA optics, ensuring durability in dusty, humid, or mildly corrosive conditions. Its 4-pin M12 male connector simplifies installation and ensures strong signal integrity. Despite its robust performance, the sensor weighs only 18 grams, making it ideal for weight-sensitive or mobile automation systems. Backed by Sick's legacy of innovation and engineering excellence, the VTE180-2P42447 offers a cost-effective, reliable solution for OEMs and automation professionals.

The Sick WL4S-3F2130 Photoelectric Sensor is widely used in industrial automation to detect the presence or absence of small parts, bottles, labels, or packages moving on conveyors. It plays a crucial role in tasks such as part positioning, product counting, and object sorting in packaging, bottling, food, and assembly lines.

For junior engineers and technicians, this sensor is easy to install thanks to its visible red beam, compact size, and standard M12 connector. You don’t need special software or calibration tools — just mount the sensor, set the range with the potentiometer, and it’s ready to use. Its IP67 protection makes it a strong fit for Indian manufacturing floors that deal with dust, vibration, or occasional water sprays.

For senior maintenance engineers, the WL4S-3F2130 delivers excellent performance in high-speed environments where precision and repeatability matter. The short response time ensures the sensor reacts instantly without lag, reducing downtime and improving machine throughput. Engineering students can observe how real-world automation relies on sensing technologies, understanding how beam angle, light wavelength, and surface reflectivity affect sensor performance. This clarity, reliability, and ease of integration make Sick Photoelectric Sensors a smart investment across industries.
