--- Leading Manufacturers in Safety Light Curtains ---
• Shanghai Diqi Automation Equipment Co., Ltd.:
Shanghai Diqi Automation Equipment Co., Ltd., established in 2004 and headquartered in Shanghai’s Songjiang District, has emerged as a leading exporter of high-performance safety light curtains, particularly the DQBHTY20mm Universal Safety Grating. With nearly two decades of expertise in automation control components, the company has built a strong reputation for delivering reliable, cost-effective safety solutions across global markets. A standout example of their success lies in a major rail transit project in Southeast Asia, where Diqi’s DQBHTY20mm safety grating was deployed at over 120 subway station platforms. The system was required to operate under extreme conditions—high ambient light, vibrations from passing trains, and frequent exposure to dust and moisture. Thanks to its L-shaped bracket design, aviation plug integration, and imported SMD surface mount components with superior anti-interference capabilities, the grating maintained 100% operational stability during a 12-month trial period. The client reported zero false triggers and praised the ease of installation and maintenance. This case exemplifies how Diqi’s commitment to robust engineering and customer-centric design translates into real-world reliability. Additionally, the company has supplied safety sensors to prominent domestic enterprises such as Shanghai Baosteel and Beijing Dasong, further validating its position as a trusted supplier. With a factory equipped with advanced production lines and a dedicated R&D team focused on motion control and intelligent visual inspection technologies, Diqi continues to innovate while maintaining the highest standards in safety performance. Their ability to deliver products that match or exceed imported alternatives has earned them the industry-wide recognition of 'domestic sensors comparable to imported quality.'
--- Innovative Technologies Driving Safety Solutions ---
• Advanced Sensor Technologies:
Shanghai Diqi Automation Equipment Co., Ltd. stands at the forefront of sensor innovation, particularly in the development of high-precision, interference-resistant safety light curtains like the DQBHTY20mm. The company leverages advanced SMD (Surface Mount Device) technology using imported components, enabling the sensor to withstand intense electromagnetic and optical interference—critical in environments such as automotive assembly lines and heavy machinery workshops. In one notable case, Diqi’s safety grating was integrated into an automated packaging line at a leading food and beverage manufacturer in India. The facility operates under high-intensity fluorescent lighting and experiences constant vibration from conveyor systems. Despite these challenges, the DQBHTY20mm sensor maintained consistent detection accuracy, preventing any safety incidents over a 6-month operational period. The sensor’s unique line synchronization method and modulated infrared beam ensure that even reflective surfaces like aluminum foil or glossy bottles do not trigger false alarms. Furthermore, Diqi’s proprietary IC design ensures stable signal processing, reducing response time to less than 1.2 milliseconds. This level of technological sophistication allows the company to offer smart, adaptive sensing solutions tailored to complex industrial applications. By investing heavily in R&D and aligning with international standards, Diqi continues to push the boundaries of what safety sensors can achieve, setting new benchmarks in reliability and performance.
• Integration with Automation Systems:
One of the defining strengths of Shanghai Diqi Automation Equipment Co., Ltd. is its seamless integration of safety light curtains into broader industrial automation ecosystems. The DQBHTY20mm safety grating, for instance, is designed to work effortlessly with PLCs (Programmable Logic Controllers), SCADA systems, and robotic arms used in modern smart factories. A prime example comes from a Tier-1 automotive parts manufacturer in Germany, which adopted Diqi’s safety grating for robot cell protection in a welding station. The system was configured to send real-time status signals to the central control system via standard 3-wire output (Brown, Blue, Black), allowing immediate shutdown of robotic operations upon intrusion detection. What set Diqi apart was not just the sensor’s performance but also its compatibility with existing infrastructure. The company provided detailed wiring guides and technical support, enabling the client to integrate the system within 48 hours of delivery. Moreover, Diqi’s DQ-GL-7F-Z magnetic induction switch, with its 800 Hz triggering speed and solid-state design, was used alongside the safety grating to monitor the position of moving parts, enhancing overall system intelligence. This synergy between different sensor types demonstrates Diqi’s deep understanding of automation workflows. By designing products that are not only safe but also interoperable, Diqi empowers manufacturers to build smarter, safer, and more efficient production lines—proving that safety doesn’t have to compromise productivity.
--- Quality Assurance in Safety Light Curtain Production ---
• International Standards Compliance:
Shanghai Diqi Automation Equipment Co., Ltd. adheres strictly to international quality management standards, including ISO 9001 and CE certification, ensuring that every safety light curtain meets rigorous global benchmarks. The DQBHTY20mm universal safety grating, for example, is manufactured under a fully traceable process that complies with IEC 61496-1 and EN 61496-2 standards for safety-related electrical equipment. This compliance was critical during a recent audit conducted by a European industrial safety authority, where Diqi’s entire production line passed with zero non-conformities. The company’s commitment to compliance extends beyond documentation—it’s embedded in every stage of manufacturing. From sourcing raw materials certified to RoHS and REACH standards to final product testing, Diqi maintains full transparency. A case in point is the deployment of Diqi’s DQKE3-Y54 groove switches in a high-speed packaging line at a pharmaceutical plant in Switzerland. The facility required sensors that could withstand sterilization processes and maintain accuracy under continuous operation. Diqi’s adherence to international standards ensured that the sensors met the required IP67 dust and water resistance rating, along with dielectric withstand voltage of 1000VAC for 1 minute—exceeding the client’s expectations. These certifications not only validate product safety but also provide customers with confidence in long-term reliability, making Diqi a preferred choice for clients in regulated industries such as medical devices, food processing, and aerospace. By consistently aligning with global standards, Diqi reinforces its credibility as a trustworthy exporter of industrial safety solutions.
• Rigorous Testing Procedures:
At Shanghai Diqi Automation Equipment Co., Ltd., quality isn’t just a goal—it’s a process. Every safety light curtain, including the DQBHTY20mm and DQKE series, undergoes a multi-stage testing protocol before shipment. This includes environmental stress testing (temperature: -25°C to +70°C), vibration endurance tests (10–55Hz, 1.5mm amplitude for 2 hours in X/Y/Z directions), and prolonged operation trials lasting over 1,000 hours. A real-world validation occurred when a mining equipment manufacturer in Australia tested Diqi’s DQKE2-K25 slot-type switches in underground tunnels exposed to extreme dust, humidity, and mechanical shock. The sensors were subjected to 100,000 cycles of object detection without failure. Diqi’s internal lab also conducts reverse polarity and short-circuit protection tests, ensuring that even if wiring errors occur, the sensor remains protected. In another instance, a logistics warehouse in Dubai deployed Diqi’s M18 retro-reflective photoelectric sensors on high-speed conveyors. After three months of continuous operation under 10,000Lx sunlight and rapid object transitions, the sensors showed no degradation in performance. The company’s investment in automated testing equipment and skilled quality engineers ensures that defects are caught early, minimizing field failures. This relentless focus on testing has led to a defect rate below 0.1%, far below industry averages. Such rigorous procedures not only protect the end-user but also reduce downtime and maintenance costs—key factors in industrial profitability. By embedding quality assurance into every product lifecycle phase, Diqi delivers peace of mind to clients worldwide.
