Collision Avoidance for AGVs and Mobile Robots
The fast response time and high accuracy of this sensor enable real-time obstacle detection. It prevents collisions in autonomous vehicles by identifying objects even in dim or reflective conditions, enhancing safety in dynamic industrial environments.
Overlapping Material Detection in Woodworking
The sensor’s fine resolution and repeatability allow it to differentiate between slightly overlapping boards or planks. This precision is crucial in automated cutting or stacking, where exact position detection ensures proper alignment and reduces waste.
Automated Tank and Bin Level Monitoring
Ideal for mobile robots or stationary systems, the Dx35 can monitor fluid or material levels in containers without contact. Its laser can reliably detect shiny, uneven, or moving surfaces, making it suitable for inventory control and refill automation.
Glossy or Dark Object Sensing in Automotive Assembly
Where conventional sensors struggle with matte black or highly reflective parts, the Dx35’s advanced signal processing ensures consistent detection. This enables accurate part positioning, inspection, or robotic pick-and-place operations on assembly lines.
Space-Constrained OEM Machinery Integration
Its compact form factor and M12 connector make the sensor easy to integrate into machines with limited space. Despite its size, it delivers high-precision data, making it perfect for robotic arms, test jigs, or compact sorting equipment.
Reliable Sensing in Harsh Manufacturing Environments
With IP67-rated protection, the sensor resists water, dust, and vibration. Its stable measurement performance in contaminated areas ensures that systems like packaging or material flow control continue working without interruption or cleaning downtime.
Fast-Moving Object Tracking on Production Lines
Thanks to configurable speeds and output response times, the Dx35 can track products moving at variable speeds. This is especially useful in sorting or printing lines where the position and timing of fast-moving items must be precisely detected.
