Sick VSE180-2P41132 Photoelectric Sensor

The Sick VSE180-2P41132 Photoelectric Sensor operates on a through-beam principle, offering exceptional detection performance across long distances with high reliability. With a sensing range of 0 to 20 meters and a maximum capability of 28 meters, it is ideal for use in fast-paced industrial automation systems where accurate object detection is required even across large conveyor widths or guarded zones. It emits a visible red light via a high-performance LED light source at 645 nm wavelength, and its focused optical axis (approx. 5°) ensures consistent detection even in challenging ambient light conditions. The sensor projects a well-defined light spot of Ø 1,100 mm at 20 meters, which makes alignment and commissioning easier during installation.

Engineered in a durable metal cylindrical housing (nickel-plated brass and PC), this sensor measures 18 mm x 18 mm x 62.5 mm and features a threaded M18 x 1 interface for easy mounting. It supports light ON/dark ON switching via a PNP output, with selectable modes through a simple L/D control cable. The device responds in under 0.5 milliseconds and handles switching operations up to 1,000 Hz, enabling real-time interaction with fast-moving components. It is powered by a 10 V DC to 30 V DC supply, maintaining low ripple tolerance (±10%) and high output current support (≤ 100 mA).

Protection against dust and moisture is assured with an IP67 enclosure rating, and its internal optics, made from PMMA plastic, maintain optical integrity over time. The integrated 270° sensitivity potentiometer allows users to fine-tune the sensor response based on object size and material. With a 2-meter, 4-wire cable for streamlined connectivity and robust build quality, the VSE180-2P41132 is widely trusted in logistics, bottling lines, and safety-critical automation zones.

The Sick WL4S-3F2130 Photoelectric Sensor is commonly used in industrial automation setups to detect whether a product has arrived at a workstation, passed a certain point on a conveyor, or entered a packing zone. This simple detection can trigger machines to stop, label, or sort automatically—improving speed and reducing errors.

For junior maintenance engineers, this sensor is easy to align thanks to its clearly visible red light and wide detection range. Its reliable through-beam design means fewer false triggers even in dusty or reflective environments. With a fast response time of 0.5 ms, it ensures nothing gets missed, even in high-speed operations.

Senior engineers trust this series for long-term stability and repeatable accuracy, especially in harsh conditions where traditional sensors may fail. The Sick build quality, strong IP67 protection, and simple wiring design make it a go-to choice for system integrators. For engineering students, the WL4S-3F2130 offers a hands-on understanding of photoelectric technology and how sensors interact with PLCs in real-world automation workflows. It’s more than a sensor—it’s a reliable control point in modern smart factories.
