Sick VTF180-2P42412 Photoelectric Sensor

The Sick VTF180-2P42412 Photoelectric Sensor is a high-performance background blanking proximity sensor designed for scenarios where false triggers from reflective backgrounds must be eliminated. Operating with a visible red LED light at a wavelength of 645 nm, the sensor delivers pinpoint accuracy using a light spot size of Ø 8 mm at 100 mm. This allows for consistent detection of small or irregularly shaped targets across a working sensing range of 1 mm to 100 mm, extendable up to 140 mm — a feature especially valuable in packaging, labeling, and fine-positioning applications.

The sensor is housed in a metal body with nickel-plated brass and PC construction, making it resistant to shock, vibration, and harsh environmental conditions. With its IP67 enclosure rating, the device can withstand washdowns and dusty environments. The compact form factor (measuring 18 mm x 18 mm x 69.8 mm) and M18 x 1 thread diameter make it simple to integrate into most mechanical assemblies. A 270° potentiometer is included to finely adjust the sensing range on-site without requiring any additional software or programming tools.

Powered by a 10 V to 30 V DC supply with ±10% ripple tolerance, the sensor operates efficiently at 30 mA current consumption. Output is configured via PNP switching with both light ON and dark ON modes selectable through a dedicated L/D control cable. With a fast response time of ≤ 0.5 ms and switching frequency up to 1,000 Hz, the VTF180-2P42412 delivers high-speed performance in automation lines. Connection is achieved through a secure M12 4-pin male connector, ensuring reliable signal transmission even in high-vibration setups.

The Sick WL4S-3F2130 Photoelectric Sensor is widely used in automated production lines for real-time detection of product presence, absence, or misalignment. Whether it’s monitoring small packages, aligning labels, or triggering sorting mechanisms, this sensor plays a critical role in ensuring smooth material flow.

For junior engineers and technicians, the sensor’s visible red light beam makes alignment straightforward during setup. There's no complicated calibration — just mount, adjust the sensing range with the potentiometer, and it's ready. The IP67 protection ensures it keeps working even in dusty or damp environments, common in Indian manufacturing floors.

Senior maintenance professionals appreciate the high-speed response time and repeatable accuracy, which help avoid downtime and false stops in conveyors. The sensor’s axial detection path ensures precise sensing when components pass directly in front, while the background suppression prevents interference from reflective machinery or surroundings. Engineering students can learn how advanced detection works in real-world scenarios, including understanding factors like response delay, target contrast, and connector types — helping bridge theoretical concepts with practical control systems.
