Sick VSE180-2P42437 Photoelectric Sensor

The Sick VSE180-2P42437 Photoelectric Sensor is a high-performance through-beam sensor built for industrial automation scenarios that require consistent, long-range object detection with high switching accuracy. This sensor offers a maximum sensing distance of 28 meters and a guaranteed operational range of 0 to 20 meters. It emits a visible red LED light with a wavelength of 645 nm, forming a concentrated Ø 1,100 mm light spot at 20 meters, allowing precise targeting even over extended distances. The optical components are protected by PMMA plastic lenses housed in a robust cylindrical M18 plastic body with nickel-plated PBT/PC material, engineered for tough and dusty environments.

Designed for axial alignment, the VSE180-2P42437 features a 270° sensitivity adjustment potentiometer for easy calibration, and operates reliably within a temperature range of –25 °C to +55 °C. It supports light ON/dark ON switching and provides a PNP output with a maximum output current of 100 mA. With a swift response time of ≤ 0.5 ms and a high switching frequency of 1,000 Hz, it ensures real-time detection even in high-speed production systems. The integrated M12 4-pin male connector simplifies installation and wiring. Rated at IP67, this sensor is fully sealed against dust ingress and water immersion, offering reliable performance across a wide range of industrial applications including food processing, packaging, automotive, and material handling.

Weighing just 36 grams, the sensor delivers industrial-grade precision without adding weight to compact setups. Its immunity to background reflection and ability to focus on exact object positions make it a trusted solution in safety-critical and quality-sensitive automation processes.

The Sick WL4S-3F2130 Photoelectric Sensor is used to detect objects without physical contact, making it ideal for industries like packaging, FMCG, and electronics assembly. It can detect the presence of a part on a conveyor, verify alignment during packaging, or trigger a signal when an object enters or exits a zone.

For junior maintenance engineers, this sensor is easy to set up thanks to its visible red light beam. You can visually align it during installation, and it connects via a standard M12 connector. Once aligned, it works instantly—no complex configuration required. Its fast response time of 0.5 milliseconds ensures you don’t miss fast-moving objects, which is especially useful on conveyor belts or packaging lines.

Senior engineers trust this sensor for its stability and low maintenance. Even in dusty or oily environments, it continues to perform accurately. Engineering students learning automation get hands-on exposure to real-world sensing technologies that work with PLCs. They can clearly understand how sensors like WL4S-3F2130 help improve machine efficiency and safety. Every function, from object detection to triggering machine actions, becomes easier and smarter with reliable sensors like this.
