1. Precision Background-Suppressed Sensing for Dynamic Industrial Environments
The LEUZE FRK92/4-300L is a compact diffuse reflective sensor with 300 mm background suppression (L-version), designed for reliable detection of objects in cluttered settings. Leveraging its red LED light source and light/dark switching capability, it ignores background surfaces up to 300 mm, focusing solely on target objects—ideal for small parts, plastic components, or low-contrast materials on conveyor lines. Its 4-mm spot size (via M12 lens) ensures precision in tight spaces, while the 1000 Hz switching frequency (1 ms response) supports high-speed automation. Rated for 10–30 V DC operation, it features a PNP transistor output and M12 4-pin connector for quick integration. Built with a zinc die-cast housing and IP67 protection, it withstands dust, vibrations, and splashes in packaging, automotive, or logistics applications. (Key specs: Range 0–300 mm, ±10% ambient light immunity, 270° rotatable housing.)
2. Rugged Design for Harsh Industrial Conditions
Engineered for durability, the FRK92/4-300L combines a metal housing (28 x 28 x 40 mm) with a scratch-resistant plastic lens to endure impacts and chemical exposure. Its IP67/IP69K rating (optional with gasket) makes it suitable for washdown zones in food processing or pharmaceutical lines. The sensor operates across -25°C to +55°C, with a 270° potentiometer for easy sensitivity adjustment—critical for adapting to glossy surfaces or varying light conditions. A built-in alignment LED simplifies setup, reducing commissioning time. Weighing just 55g, it mounts via M4 threads or brackets, integrating seamlessly into cramped machinery. (Unique feature: Reverse polarity protection + short-circuit immunity for 24V systems.)
3. Versatile Integration for Smart Factory Applications
The FRK92/4-300L bridges reliability and flexibility, supporting AS-Interface compatibility (via optional adapter) for IIoT-ready networks. Its light-on/dark-on switching (selectable via potentiometer) suits diverse use cases: detecting black rubber on white conveyors (dark-on) or clear bottles on dark backgrounds (light-on). Certified to IEC 60947-5-2 and cULus, it meets global safety standards for automotive, electronics, and warehousing. Typical applications include counting small parts, positioning in pick-and-place robots, or quality control in packaging lines. Pair it with Leuze’s 50008267 reflector for retroreflective mode (extends range to 6 m) or use it standalone for cost-effective background suppression. (Bonus: 3-year warranty on Leuze’s industrial-grade sensors.)
