The Pfannenberg QUADRO LED-HI DC YE 21108633000 is a high-intensity yellow LED visual signalling light designed to provide clear and highly visible status indication in demanding industrial environments. As part of the robust Pfannenberg QUADRO LED-HI series, it combines powerful LED technology, a durable enclosure and flexible signalling modes for machinery, automation and safety applications.
This industrial LED signal light provides adjustable light intensity up to 75 cd and supports continuous, blinking and flashing operating modes. The DC version allows operating modes to be selected internally or externally, providing flexibility when integrating the unit into automated machinery and control systems.
With a 12–48 V DC rated voltage range, an operating range of 11–60 V DC and nominal current consumption of 165 mA at 24 V DC, the QUADRO LED-HI is well suited to industrial DC control systems. Its IP66/IP67 and IK08 protection, UV-resistant polycarbonate construction and wide operating temperature range make it suitable for both indoor and outdoor installations.
High-intensity LED signalling devices such as the Pfannenberg QUADRO LED-HI provide immediate visual indication of machine states, process conditions and warnings. The large illuminated surface and powerful LED output make the signal easy to recognise, helping operators identify equipment conditions quickly in busy industrial environments.
The QUADRO LED-HI series is engineered for demanding industrial conditions where reliability and visibility are essential. Its selectable signalling modes, wide DC operating range, shock and vibration resistance and high enclosure protection make it suitable for integration with machinery, conveyors, cranes, material handling systems and automated production equipment.
