Sick VL180-2P42438 Photoelectric Sensor

The VL180-2P42438 Photoelectric Sensor from Sick operates on a dual-lens retro-reflective principle, offering high precision and reliable signal stability even in challenging industrial environments. With a radial optical axis and cylindrical body design, this sensor fits seamlessly into space-limited installations. Its housing, built from robust PBT/PC plastic, measures 18 mm x 18 mm x 84.2 mm, offering protection against both mechanical stress and environmental exposure. The optical system emits a visible red LED light with a wavelength of 645 nm, forming a clearly visible Ø 270 mm light spot at 4 m. The sensor operates at a sensing range of 0.05 m to 4.5 m, extendable up to 5.5 m, making it ideal for long-range detection tasks across packaging, palletizing, and conveyor systems.

For signal responsiveness, the sensor supports a fast response time of ≤ 0.5 ms with a switching frequency of 1,000 Hz, powered efficiently by a 10 V to 30 V DC supply and consuming only 30 mA. It delivers output through a reliable PNP configuration with light/dark switching modes, ideal for seamless PLC integration. Engineers can tune the detection sensitivity using the integrated 270° potentiometer, while the M12 4-pin male connector ensures stable electrical connections in high-vibration or high-dust environments. With an IP67-rated enclosure and operating temperature range of –25 °C to +55 °C, the VL180-2P42438 is built to perform under rigorous industrial conditions.

With trusted German engineering from Sick, this sensor offers the precision, longevity, and flexibility that OEMs and system integrators in India demand. For detailed documentation, specifications, and certifications, visit the official Sick website.

The Sick WL4S-3F2130 Photoelectric Sensor is ideal for real-time object detection in applications such as product positioning, package counting, and machine safety. It’s especially useful in conveyor systems where fast and accurate detection is required to prevent bottlenecks or misplacements.

For junior maintenance engineers, the sensor’s red light beam and compact housing make it easy to align and install. There’s no need for software configuration — just wire it in, adjust the sensitivity via the built-in potentiometer, and it's ready to detect. The clear sensing range and rugged housing simplify daily operations even in dusty or humid conditions.

Senior engineers rely on the WL4S-3F2130 and related Sick models for dependable detection regardless of surface color, background reflectivity, or lighting fluctuations. Its rapid response time and industrial-grade IP67 rating make it an optimal choice for automated packaging, bottling lines, and high-speed sorting equipment. For engineering students, it provides a practical understanding of how retro-reflective sensors work, and why correct alignment, beam angle, and background suppression are critical in smart factory design.
