Product Description
Dialight 591-3001-002F is a high-quality bistable bi-colour LED indicator designed for surface mount printed circuit boards. Operating at a forward voltage of 2.5 V and a maximum forward current of 30 mA, this component meets industrial standards for reliable status indication.
The device integrates two LEDs (red and green) housed within a compact black plastic enclosure, offering excellent contrast and visibility in various lighting conditions. The round dome-shaped lens with a clear finish provides a wide 40° viewing angle and consistent luminosity of 6.58 mcd, suitable for clear indication in diagnostic or signaling applications.
This PCB LED Indicator is part of the Dialight 591 series, known for ruggedness and installer-friendly surface mounting facilitated by its ELA-481-2 package. The unit's small physical dimensions (8.77 x 4.32 x 5.03 mm) enable compact PCB designs while maintaining robust performance.
The product is supplied in tape & reel format, optimizing it for automated pick and place assembly lines in electronics manufacturing. It is particularly used in industrial power distribution boards, control panels, and instrumentation where dual status indication is required.
The LED color options include red and green, covering a wide range of signaling needs. Its forward voltage is rated at 2.5 V, ensuring compatibility with low voltage DC circuits. The maximum power dissipation of 100 mW allows for efficient operation with minimal heat generation.
The design includes 2 pins optimized for surface mount applications on printed circuit boards. The black plastic housing and clear lens finish contribute to high contrast and visual legibility of the LED colors.
Dialight 591-3001-002F is suitable for industrial, electronic components, power connectors, display units, and manufacturing environments requiring reliable LED indicators. It offers easy integration with PCB designs and ensures consistent operational longevity.
