Dialight 559-3501-007F Panel Mount LED Indicator, HE-Red/Green

The Dialight 559-3501-007F is a high-efficiency, bi-colour panel mount indicator LED, designed to provide clear visual status signals in a wide range of electronic and industrial applications. Featuring both red and green diffused LEDs within a single compact unit, it offers a reliable and versatile solution for equipment indicating power on/off, operational modes, or fault conditions.

The indicator is engineered for quick and secure installation, featuring a snap-in mounting design that requires no additional hardware for panels with a thickness between 0.787mm and 1.57mm. This facilitates a clean, professional finish with uniform illumination across the lens, ensuring the status signal is easily visible from a wide viewing angle of 65 degrees.

Technical Performance

• The red LED emits a peak wavelength of 635nm with a luminous intensity of 5 millicandelas (mcd).
• The green LED emits a peak wavelength of 565nm with a higher luminous intensity of 8 mcd.
• Both colours operate at a standard forward current of 10mA, with forward voltages of 2.1V for red and 2.3V for green.
• The component is IC compatible, making it suitable for direct integration into various circuit designs.
• Built for durability, it performs reliably across an operating temperature range from -20°C to +85°C.

With its straightforward 3-leaded wire termination for positive insertions, robust construction, and consistent optical performance, this Dialight LED indicator is an excellent choice for adding clear, dependable visual feedback to control panels, machinery, instrumentation, and custom electronic assemblies.
