Leuze PRK 53/6D.421-S8.3 | 50113279

Built with robust engineering, the Leuze PRK 53/6D.421-S8.3 is designed around a cubic stainless steel housing (AISI 316L), offering maximum durability and corrosion resistance in washdown environments. It uses a reflection principle with a divergent beam path and an LED red light source operating at 620 nm. This combination allows accurate object detection within a range of 0 to 3 meters, making it suitable for transparent or low-contrast object sensing.

This photoelectric sensor operates with a 10–30 V DC supply voltage and features a push-pull transistor output, compatible with both PNP and NPN logic. Its switching frequency of 1,000 Hz and 0.5 ms response time enable fast and precise object detection in high-speed automation setups. The 3-pin M8 connector supports easy installation and maintenance. The integrated LED status indicator and Teach button simplify configuration for on-site adjustments without requiring external tools.

The device maintains operational stability across extreme temperatures ranging from -30°C to +70°C, and its IP67/IP69K protection ensures resilience against water, dust, and high-pressure cleaning agents. The scratch-resistant Indium-coated lens further enhances its reliability in hygiene-sensitive sectors like food, beverage, and pharmaceutical manufacturing.

When accuracy, hygiene, and durability are critical, the Leuze PRK 53/6D.421-S8.3 Photoelectric Sensor stands out as the industry’s trusted solution.

The Leuze PRK 53/6D.421-S8.3 Photoelectric Sensor is optimized for detecting highly transparent bottles in automated filling and labeling systems. These containers often fail to trigger conventional sensors due to their low reflectivity. Leuze’s autocollimation and divergent beam design solve this challenge by delivering consistent object recognition across the full 0 to 3 meter sensing range.

For Indian senior maintenance engineers working in fast-paced bottling lines, the 0.5 ms response time ensures accurate switching even when conveyor speeds are high. The hygiene design, backed by a stainless steel AISI 316L body and IP69K protection, means the sensor remains reliable in wet zones and after frequent cleaning cycles. Younger technicians and students benefit from easy plug-and-play setup with the 3-pin M8 connector and real-time feedback through the LED indicator.

In industries like food processing, pharma packaging, and beverage manufacturing, where transparent materials and fast operations coexist, the Leuze PRK 53/6D.421-S8.3 Photoelectric Sensor provides a powerful sensing solution. Its advanced optical system and rugged body make it ideal for line integration, reducing downtime and improving detection reliability across automated systems.
