1. High-Precision Distance Measurement with Advanced Technology
The SICK DT35-B15251 is a mid-range distance sensor engineered for industrial automation applications requiring precise and reliable measurements. Leveraging HDDM™ (High Definition Distance Measurement) technology, it delivers a measuring range of 50 mm to 12 m for natural objects and up to 35 m with reflective tape . Its red laser light source (Class 2) ensures high immunity to ambient light interference, while the ±10 mm accuracy and 0.1 mm resolution enable detailed object detection and positioning. The sensor supports multiple output options, including 4–20 mA current, 0–10 V voltage, and PNP/NPN push-pull digital signals, with configurable switching modes (e.g., distance-to-object, switching window) via IO-Link . With a response time as fast as 2.5 ms and 333 Hz switching frequency, it excels in high-speed processes like conveyor belt monitoring or robotics guidance.
2. Versatile Applications for Diverse Industries
Designed for flexibility and ruggedness, the DT35-B15251 thrives in demanding environments. In logistics and warehousing, it accurately detects empty bays in automated storage systems or monitors fill levels in bulk material silos . For packaging lines, its laser-based precision ensures consistent product alignment and quality control. The sensor’s IP65/IP67-rated housing and -30°C to +55°C operating temperature range make it suitable for outdoor or washdown applications, such as automotive assembly plants or food processing facilities . Its compact size (32 x 58.6 x 42.7 mm) and M12 connector simplify installation in confined spaces, while the teach-in function allows quick adaptation to changing object characteristics.
3. Smart Features and Reliable Performance
The DT35-B15251 integrates IO-Link v1.1 for seamless parameterization, diagnostics, and data exchange, enhancing connectivity with industrial networks . Its 100,000-hour laser lifespan and stainless steel-reinforced housing ensure long-term durability, reducing maintenance costs. The sensor also offers multiple speed settings (super fast to super slow) to balance measurement speed and accuracy, making it ideal for both rapid scanning and high-precision tasks. Additional features include reverse polarity protection, short-circuit immunity, and LED status indicators for easy troubleshooting. Compliant with CE, RoHS, and IEC 60825-1 standards, it meets global safety requirements for industrial use . Whether in material handling, robotics, or process automation, the DT35-B15251 combines cutting-edge technology with user-friendly design to optimize productivity and reliability.
