The Leuze PRK53C.TT3/LG-M8 is a compact retro-reflective photoelectric sensor designed for hygiene-critical and space-constrained environments. With a robust cubic stainless steel housing measuring just 14 mm Γ 35.4 mm Γ 20.4 mm, this sensor is built for durability and long-term performance. It operates on the reflection principle with an autocollimation system, allowing it to detect highly transparent bottles and films with precision, even in the presence of intense background reflections. The device features a red LED light source with a 645 nm wavelength, delivering a focused beam and accurate signal differentiation across a sensing range of 0 to 3 meters when paired with the TK(S) 100x100 reflector. The push-pull transistor outputs support both PNP and NPN switching, compatible with modern PLCs via IO-Link for smart diagnostics and flexible integration. Its switching frequency of 1,500 Hz and 0.33 ms response time make it ideal for high-speed bottling, labeling, and packaging systems. The 10β30 V DC supply voltage, IP67/IP68/IP69K protection rating, and scratch-resistant PMMA+ lens ensure it withstands washdowns, dust, and vibration. All electrical connections are made via a reliable M8 4-pin male connector. Engineered with AISI 316L-grade stainless steel and a visible LED indicator for quick status checks, the PRK53C.TT3/LG-M8 brings operational ease, hygiene compliance, and top-tier detection performance to industrial automation lines. It is trusted globally by OEMs and maintenance engineers for reducing false triggers and minimizing downtime in transparent object detection tasks.
The Leuze PRK53C.TT3/LG-M8 Photoelectric Sensor is specifically engineered for industries where accurate detection of clear or curved surfaces is critical. Whether it's a transparent PET bottle on a high-speed conveyor or a thin film wrapping product in a packaging machine, this sensor ensures each item is reliably identified and tracked without misreads or false triggers.
Thanks to its autocollimation optics and high-frequency switching, it operates flawlessly even in spaces where traditional sensors struggleβsuch as near shiny metal backgrounds or in damp areas with aggressive cleaning protocols. For automation engineers and maintenance teams, this means fewer false signals, smoother line operation, and less manual intervention, especially in applications like labeling, filling, and film feed control.
For Indian manufacturers and plant managers seeking to upgrade detection accuracy and reduce production stoppages, the Leuze PRK53C.TT3/LG-M8 Photoelectric Sensor offers a proven, robust solution. It is not only a reliable sensor but also a critical tool for increasing efficiency and product quality in transparent object handling.
