The Leuze PRK 53/6.42-S8 is engineered with a cubic stainless steel housing (AISI 316L), combining rugged construction with hygiene-grade durability. Using the reflection principle and divergent beam path, it enables accurate object detection up to 3 meters, even when dealing with transparent or low-contrast targets. A high-performance LED red light source at 620 nm forms a round spot geometry that ensures consistent signal strength across varying surface materials.
Operating at a supply voltage of 10 to 30 V DC, this photoelectric sensor offers a versatile push-pull transistor output with light switching (PNP) and dark switching (NPN) capabilities. With a fast response time of 0.5 ms and switching frequency of 1,000 Hz, itβs optimized for real-time automation processes. The 4-pin M8 connector with A-coding ensures reliable connectivity and supports both signal IN and OUT functions. The housing includes a scratch-resistant Indium-coated plastic lens and a visible LED indicator for easy alignment and status checks.
Whether installed in food, beverage, or pharmaceutical automation lines, the PRK 53/6.42-S8 stands up to harsh washdowns and temperature extremes from -30Β°C to +70Β°C. Rated at IP67/IP69K, it ensures dust-tight, water-resistant performance under pressure. For full specifications, visit the official Leuze Photoelectric Sensors page. The Leuze PRK 53/6.42-S8 Photoelectric Sensor remains a top choice where hygiene, accuracy, and durability are mission-critical.
The Leuze PRK 53/6.42-S8 Photoelectric Sensor is ideally suited for detecting highly transparent bottles in industries such as bottled water, pharmaceuticals, and cosmetics. Transparent containers often fail to reflect enough light for standard sensors. However, this model solves that problem through its autocollimation optics and divergent beam path, ensuring reliable detection without false triggers.
Senior maintenance engineers will appreciate the 0.5 ms response time, which allows the sensor to track even high-speed bottle lines without error. Its LED indicator gives instant visual feedback during setup, and the Teach button allows fast, on-site calibration. With its stainless steel design and IP69K rating, this sensor is ready for regular cleaning cycles and harsh plant conditions.
For engineering students and junior technicians, the plug-and-play 4-pin M8 connector simplifies installation, while the integrated display reduces troubleshooting. This makes the Leuze PRK 53/6.42-S8 Photoelectric Sensor a smart, future-ready component for automation systems that deal with transparent or reflective materials.
