Pfannenberg QUADRO LED-HI-3G/3D LV RD 21108635009 is a red 12–48 V DC Ex-ATEX LED visual signalling light with adjustable brightness up to 75 cd, continuous, blinking and flashing modes, and IP66/IP67 protection for Ex Zone 2 and Zone 22 applications.
The Pfannenberg QUADRO LED-HI-3G/3D LV RD 21108635009 is a high-intensity red Ex-ATEX LED visual signalling light designed for clear warning, alarm and machine-status indication in demanding industrial and hazardous-area applications. As part of the Pfannenberg QUADRO LED-HI 3G/3D series, it is certified for use in Ex Zone 2 and Zone 22 environments where potentially explosive gases or combustible dust may occur.
This industrial LED signal light provides user-adjustable brightness up to 75 cd and offers continuous, blinking and flashing signalling modes. The combination of high-output LED technology and selectable signalling patterns allows the visual indication to be adapted to different alarms, machine states and process conditions while providing excellent visibility in industrial working areas.
With a rated supply of 12–48 V DC and a wide 11–60 V DC operating range, the QUADRO LED-HI-3G/3D LV RD integrates readily with industrial low-voltage control systems. Its compact 130 × 130 × 130 mm enclosure, IP66/IP67 environmental protection and IK08 impact resistance make it suitable for demanding indoor and outdoor installations.
Visual signalling equipment used in hazardous areas must provide effective indication while being designed and approved for the intended installation environment. The Pfannenberg QUADRO LED-HI 3G/3D series is suitable for Ex Zone 2 and Zone 22 applications, providing a powerful red visual signal in locations where potentially explosive gases or combustible dust may occasionally be present.
The combination of adjustable LED brightness, multiple signalling modes, a wide-range DC power supply and rugged enclosure protection makes the QUADRO LED-HI-3G/3D particularly suitable for industrial automation and process applications. Redundant electrical contacts, multiple cable entry options and inrush current regulation further support reliable integration into industrial signalling and control systems.
