Sick WTV4FE-22161120A00 Photoelectric Sensor

Engineered by SICK for challenging detection tasks, the WTV4FE-22161120A00 Photoelectric Sensor delivers exceptional performance with its advanced V-optics background suppression. It can detect transparent and miniature objects with high repeatability, thanks to its sharply focused rectangular light spot measuring just 0.5 mm x 1.9 mm at a 30 mm distance. The visible red LED light operates at 635 nm, ensuring precise alignment and clean signal clarity even in dynamic lighting conditions.

The sensor’s compact sensing range of 2 mm to 50 mm makes it ideal for detecting objects like glass vials, plastic films, wires, and PCB edges. At the heart of its smart design is Teach-Turn adjustment with IO-Link, enabling quick configuration and remote diagnostics for modern Industry 4.0 environments. It supports two complementary push-pull outputs (PNP/NPN), delivers a fast response time of ≤ 500 µs, and supports switching frequencies up to 1,000 Hz — perfect for high-speed sorting or positioning tasks.

The rugged rectangular housing, measuring just 16 mm x 40.1 mm x 12.1 mm, is built from VISTAL® plastic with a PMMA front screen, ensuring durability in harsh operating conditions. Rated to IP66 and IP67, it resists dust, moisture, and mechanical stress, while its operating temperature range of –40 °C to +60 °C ensures stable performance across extreme climates. With reverse polarity, overcurrent, and short-circuit protection built-in, this sensor is trusted by OEMs and automation experts for mission-critical applications.

The SICK WL4S-3F2130 Photoelectric Sensor is widely used in industrial automation systems where compact size, reliable detection, and consistent switching points are crucial. This includes machines for packaging, bottling, labeling, cap alignment, and electronic assembly where space is limited and precision matters.

Thanks to its fixed background suppression and visible red light beam, engineers don’t have to constantly recalibrate for different object materials or background colors. This is especially helpful in lines that handle both shiny and transparent products. For example, in a packaging line, the sensor can detect transparent pouches moving past reflective conveyors. In electronics, it can pick up thin PCB edges even in variable lighting.

Indian maintenance engineers value the WTV4FE-22161120A00 for its fast installation, high-speed switching, and low maintenance needs. Its robust performance in dusty or lightly wet environments makes it ideal for small-parts manufacturing or fast-paced assembly lines. Whether you’re an engineering student learning automation or a plant head overseeing uptime, this photoelectric sensor delivers consistent results that reduce false positives and keep production flowing smoothly.
