5580501809F

LED Indication - Discrete Overview

Dialight 558-0501-809F is a green LED panel mount indicator from the 558 series. It features a snap-in installation style with wire termination and a dome-shaped, diffused lens. The component operates at a forward current of 20 mA and a forward voltage of 2.1 VDC. It emits light at a wavelength of 565 nm with a luminous intensity of 70 mcd. The unit has a 40-degree viewing angle and requires a 4 mm mounting hole.

LED Indication - Discrete Feature Summary

• Snap-in mounting design for secure panel integration
• Diffused dome lens for uniform light distribution
• Wire termination for direct electrical connection

LED Indication - Discrete Applications

• Panel status indication
• Power supply signaling
• Equipment operational monitoring

LED Indication - Discrete Procurement Notes

Verify the exact part number against official Dialight documentation to ensure correct specifications. Confirm RoHS compliance status and lead times through authorized distributors. Check for any specific handling requirements during storage and assembly.

LED Indication - Discrete Selection Notes

Select this model when a green visual indicator with high brightness is required. The 20 mA forward current provides strong illumination compared to lower current variants. Ensure the panel cutout matches the 4 mm diameter requirement for proper fit.

LED Indication - Discrete Part Context

The 558 series consists of single-color LED indicators designed for durability. This specific part uses a standard snap-in housing suitable for various industrial control panels. It is distinct from surface-mount or PCB-only LED components.

LED Indication - Discrete Replacement Considerations

Consult official Dialight cross-reference lists for verified substitutes. Generic replacements may differ in lens shape, viewing angle, or electrical characteristics. Verify compatibility before substitution.
