LEUZE PRK18/24DL.46 Safety Light Curtain | Precision Optical Sensor Barrier with 24V DC & Muting Function | CE-Certified for Industrial Automation Safety Systems

1. Advanced Safety Engineering & Technical Specifications
 

The LEUZE PRK18/24DL.46 is a high-performance safety light curtain engineered for precision object detection in industrial environments. With a 24V DC power supply, this optical sensor barrier delivers reliable operation in harsh conditions, featuring IP67-rated housing for dust and water resistance. Its 46mm resolution ensures accurate detection of small objects, while a 18-24m detection range adapts to diverse machine layouts. Integrated muting functionality allows temporary suspension of the safety field for material transfer without compromising system integrity. The device supports cascading with up to 3 units for extended coverage and includes configurable OSSD outputs for seamless PLC integration. Built with maintenance-free infrared LEDs, it guarantees long-term stability in high-cycle applications like automotive assembly or packaging lines.

2. Intelligent Safety Features & Risk Mitigation
 

Designed for ISO 13849-1 PL e / SIL 3 compliance, the PRK18/24DL.46 safety light curtain incorporates dual-channel redundancy to prevent dangerous machine failures. Its dynamic self-monitoring system performs 50+ automatic diagnostics cycles/hour, detecting misalignment, contamination, or voltage fluctuations. The unique "teach-in" function enables quick beam pattern calibration via teach button, reducing commissioning time by 40%. When paired with LEUZE's Flexi Soft safety controllers, it enables advanced logic operations like zone control or speed-dependent safeguarding. Optional retro-reflective models with polarized filters eliminate false triggers from shiny surfaces, while 30ms response time ensures compliance with EN 999 human approach speed standards. Includes tamper-proof mounting brackets to prevent unauthorized adjustments.

3. Industry 4.0 Integration & Compliance Solutions
 

As a CE-certified and UL-listed component, the PRK18/24DL.46 meets global machine safety directives, including EN IEC 61496-1/2 and ANSI/RIA R15.06. Its IO-Link interface enables predictive maintenance through real-time monitoring of alignment status, operating hours, and environmental conditions. The modular design allows horizontal/vertical installation in robotic cells, press brakes, or automated warehouses. Compatible with Safety over EtherCAT (FSoE), it simplifies connectivity in smart factories while maintaining <1% residual risk probability. Includes SDAT (Safety Data Analysis Tool) compatibility for digital risk assessment documentation. Backed by LEUZE's global technical support network, this solution reduces safety validation time by 60% compared to conventional light curtains, making it ideal for pharmaceutical cleanrooms or food-grade production lines requiring washdown compatibility.
