What emission area sizes are available in the RODER DL2 series?

The DL2 series offers 12 standard models with emission areas ranging from 25×100 mm to 100×300 mm, covering a wide range of Machine Vision Lighting applications. Custom sizes are available upon request and may have longer production times.

How does HTTM© technology extend LED lifespan in DL2 illuminators?

HTTM© (High Transmission Thermal Material) is a special interface layer placed between the LEDs and the aluminium housing. It maximises heat transfer away from the LED junction, keeping operating temperatures stable over time to maintain consistent brightness and extend LED service life in continuous-duty Machine Vision applications.

What certifications do DL2 series LED matrix illuminators carry?

DL2 series illuminators carry CE certification and undergo mandatory 48-hour factory burn-in testing. Each unit is shipped with a test certificate confirming performance compliance, ensuring guaranteed reliability for Automated Optical Inspection and industrial automation deployments.

The DL2 Series represents a premium evolution in matrix LED illumination, specifically designed for high-performance machine vision. These illuminators combine high-intensity output with a rugged, ultra-compact form factor, making them the ideal choice for precision inspection in demanding industrial environments where space is at a premium.

Engineered for Seamless System Integration

Built for maximum reliability, the DL2 family features a “bracketless” direct mounting system and integrated protective glass, eliminating the need for external hardware. Thanks to advanced HTTM (High Thermal Transmission Material) technology and flexible cable exits, these units ensure superior thermal stability and effortless integration into any automated production line.
