Sick VTE180-2F32342 Photoelectric Sensor

The Sick VTE180-2F32342 Photoelectric Sensor is engineered for high-precision detection using an energetic sensing principle. It emits visible red LED light with a defined wavelength of 645 nm and a focused beam angle of 1.5°, allowing reliable detection across a broad sensing range of 1 mm to 350 mm, with a maximum reach of 500 mm. The sensor’s optical system produces a consistent Ø 20 mm light spot at 400 mm, providing excellent accuracy when targeting objects of varied colors and reflectivity.

Built with a compact 18 mm x 18 mm x 69.8 mm cylindrical metal housing and M18 x 1 thread design, the VTE180-2F32342 is easy to install in space-limited industrial setups. The rugged enclosure, made of nickel-plated brass and PC, provides superior durability and achieves a high IP67 protection rating, ensuring dependable performance even in dusty or washdown-prone environments. Internal components are protected from moisture, oil splashes, and temperature fluctuations ranging from –25 °C to +55 °C.

This PNP-output photoelectric proximity sensor operates on a wide 10 V to 30 V DC supply and consumes only 30 mA, making it highly energy-efficient. A 270° potentiometer offers on-site tuning of the sensing range without software, while the 3-pin M12 connector simplifies wiring for fast commissioning. With a rapid response time of ≤ 0.5 ms and switching frequency up to 1,000 Hz, the sensor is capable of detecting fast-moving objects with minimal delay.

The Sick WL4S-3F2130 Photoelectric Sensor is commonly used for position detection and material flow monitoring in automated production lines. It is ideal for detecting components on conveyors, checking the presence of packages, or aligning moving parts in bottling and packaging machines.

For junior maintenance engineers, the visible red light beam helps with easy alignment during installation. There is no need for programming—simply connect the sensor using the M12 connector, adjust the sensing range using the potentiometer, and it’s ready to detect. The robust build and IP67-rated housing ensure that it functions reliably even in dusty or humid factory environments.

Senior engineers value the sensor’s speed and accuracy, especially when integrated with high-speed PLCs or robotic systems. It consistently detects light or dark objects, transparent materials, and uneven surfaces without requiring external reflectors or background adjustment. For engineering students, this sensor provides a practical learning experience on how energetic sensors operate, how response time impacts automation, and how beam angle and object contrast play roles in accurate sensing. This clarity of operation is what makes Sick Photoelectric Sensors a reliable choice in real-world industrial automation.
