SICK Retroreflective Photoelectric Sensor Block Sensor Stainless Steel Threaded 4-Pin Connector PNP Output 5 m WLG4S-3F3434V

The SICK WLG4S-3F3434V is a high-performance retroreflective Photoelectric Sensor designed for precise detection of transparent objects in industrial environments. Featuring a compact block sensor style and housed in stainless steel, it offers superior protection with IP66, IP67, IP68, and IP69K ratings. Its 5 meter detection range and PNP output interface suit various automation systems.

This sensor incorporates advanced Pin Point LED technology, producing a small, intense light spot to allow quick and accurate alignment even with small reflectors. The single-lens autocollimation optics provide reliable detection through very small gaps or transparent materials, making it ideal for applications such as film tear detection, vial inspection, and flow mark recognition.

Setup is simplified through a teach-in pushbutton enabling quick automatic switching threshold adjustment, reducing downtime. The sensor automatically adapts to environmental factors such as temperature shifts, dust accumulation, and dirt, maintaining consistent performance. With a fast response time of 500 microseconds and a max DC voltage of 30V, it meets demanding industrial automation requirements.

The WLG4S-3F3434V is equipped with a 4-pin connector allowing easy integration and wiring. Its threaded through-hole mount design facilitates secure and flexible installation. Certified to UL File No. NRKH.E181493 and EN IEC 63000 hazardous area standards, it ensures compliance in various regulated settings.

Applications include manufacturing lines, laboratory instrument environments, packaging inspection, and quality assurance systems where accurate sensing of transparent or difficult-to-detect objects is critical. This sensor offers robust build quality, configurable settings, and precise performance in a compact form factor.
