The Leuze PRK18B.FXT3/4P-M12 Photoelectric Sensor is engineered for precision detection using the reflection principle and features advanced autocollimation optics to ensure accurate identification of transparent targets like bottles, films, or glass panes. It operates within a sensing distance of 0 to 3 meters and uses a red LED light source with a wavelength of 620 nm and LED group 1 classificationβideal for stable detection in environments with variable background or lighting conditions.
This sensor delivers exceptional performance at a switching frequency of 5,000 Hz with a fast 1 ms response time, enabling it to detect high-speed objects on production lines. It supports light switching and dark switching modes via dual PNP transistor outputs and operates on a standard 10β30 V DC power supply. The housing is constructed from diecast zinc metal with a glass lens cover, offering excellent resistance against industrial contaminants and mechanical impact. Its compact 15 mm Γ 47 mm Γ 32.5 mm form factor, combined with a metal M12 A-coded 4-pin connector, makes it suitable for space-constrained setups while ensuring electrical stability.
The sensor features a 270Β° potentiometer for precise sensitivity adjustment and a clear LED display for real-time visual diagnostics. With an operational temperature range from -40Β°C to +60Β°C and an IP67/IP69K rating, the PRK18B.FXT3/4P-M12 is built to perform reliably in harsh environments, including washdown zones, packaging halls, and outdoor industrial plants.
The Leuze PRK18B.FXT3/4P-M12 Photoelectric Sensor is designed for fast-paced production environments that demand reliable detection of transparent or reflective materials. Whether it's a pharmaceutical packaging line, an automated bottling unit, or a printing machine using clear films, this sensor ensures uninterrupted detection and consistent output.
Thanks to its high 5,000 Hz switching frequency and robust IP69K-rated housing, it excels in both dry and washdown environments found in Indian factories. The 270Β° potentiometer allows maintenance engineers to fine-tune detection sensitivity during commissioning or product changeovers. The sensorβs compatibility with standard PNP outputs and M12 connectors simplifies integration with common PLCs used in Indian automation systems.
