40mm Pitch Industrial Protection Safety Light Curtain Barrier Infrared Laser Sensor NPN PNP Output

The VIFAR is an industrial-grade safety light curtain engineered to deliver reliable machine guarding and perimeter protection in demanding manufacturing environments. Featuring a precise 40mm beam pitch with infrared laser sensor technology, this thru-beam optoelectronic safety device provides comprehensive finger and hand detection for operators working near hazardous machinery. Designed with an anodized aluminum housing and IP65 enclosure rating, the  withstands coolant mist, metal dust, vibration, and washdown conditions commonly encountered in automotive plants, metal fabrication shops, packaging lines, and pharmaceutical processing facilities. Supporting both NPN and PNP output configurations with a standard DC 24V power supply, this safety light curtain integrates seamlessly with major PLCs, safety relays, and motion controllers from Mitsubishi, and Schneider Electric, making it an ideal choice for system integrators and machine builders seeking CE-certified, SIL3/PLe-compliant safety solutions at competitive pricing.

• 40mm Industrial Beam Pitch: Optimized 40mm resolution provides reliable finger and hand detection, striking the ideal balance between safety precision and cost-effectiveness for a wide range of machinery safeguarding applications.
• Infrared Laser Sensor Array: Advanced infrared laser LED emitter technology ensures exceptional beam collimation, minimizing optical crosstalk and false tripping even in dusty, vibration-intensive industrial settings such as stamping presses and robotic welding cells.
• Dual NPN/PNP Output: Switchable NPN and PNP output modes offer maximum compatibility with diverse control architectures, eliminating the need for external signal converters and simplifying field installation for system integrators worldwide.
• Lateral L-Bracket Mounting System: The innovative side-mount bracket design reduces alignment time by up to 40% compared to conventional end-cap mounts, enabling flexible installation in tight machine frames, conveyor systems, and existing equipment retrofits.
• IP65 Rated Aluminum Housing: The rugged anodized aluminum enclosure with IP65 ingress protection delivers long-term durability against coolant spray, cutting fluids, metal shavings, and washdown procedures typical of automotive and food processing environments.
• CE Certified & SIL3/PLe Compliant: Designed and tested to meet EU Machinery Directive 2006/42/EC, ISO 13849-1 PLe, and IEC 61508 SIL3 standards, ensuring full regulatory compliance for European and North American market deployment.
• Wide Protection Range: Customizable protective heights from 60mm to 2000mm with protection distances up to 30 meters, covering everything from compact bench-top machines to large-scale robotic cells and automated production lines.

The VIFAR safety light curtain is purpose-built for industrial protection across a broad spectrum of manufacturing sectors. In automotive plants, it serves as perimeter guarding for robotic welding cells, stamping presses, and powertrain assembly stations where operator access must be continuously monitored. Metal fabrication shops deploy it to safeguard press brakes, hydraulic shears, and punching machines, with the 40mm pitch providing reliable hand detection for point-of-operation zones. Packaging and material handling facilities utilize the as access control barriers around palletizers, automated guided vehicles (AGVs), and high-speed conveyor systems, where fast response time and NPN/PNP flexibility ensure seamless integration with existing safety PLCs. In pharmaceutical and food processing environments, the IP65-rated aluminum housing withstands regular washdown procedures, making it suitable for FDA-regulated production lines. Additionally, the customizable protective height and 30-meter protection range make this safety light curtain an excellent choice for large-scale applications including automated warehouse access control, tire manufacturing press guarding, and heavy equipment perimeter protection in mining and construction machinery plants.

Every VIFAR safety light curtain is manufactured by Shenzhen Oujie Lighting Technology Co., Ltd., a professional high-tech enterprise with over 10 years of R&D expertise in optoelectronic safety devices. Operating from a 7,000-square-meter ISO-standardized factory in Shenzhen’s Longhua LED industrial cluster, our in-house engineering team handles optical design, PCB assembly, aluminum profile machining, and final functional testing under one roof. This vertical integration eliminates middleman markups, delivering up to 30-50% cost savings compared to equivalent European-brand safety light curtains while maintaining full CE, RoHS, and SIL3/PLe compliance. Each unit undergoes complete functional testing including beam alignment verification, response time measurement, and thermal cycling before shipment, ensuring a near-zero defect rate that our global customers have come to rely on.

Each VIFAR safety light curtain is packaged in a reinforced carton box lined with custom-molded EPE foam to ensure safe transit via DHL, UPS, FedEx, or TNT express shipping. Standard delivery time is 5-15 working days depending on order volume and protective height configuration. We offer flexible minimum order quantities starting from 1 set for sample evaluation, with bulk orders available at scaled pricing. All products are backed by comprehensive pre-shipment quality inspection and a standard warranty period. Custom OEM branding, protective height modifications, and special connector configurations are available upon request.
