An industrial automation manufacturer required SMD 0805 indicator LEDs for PLC output modules and HMI panels. The indicators needed clear status visibility under factory lighting, withstand Pb-free reflow soldering, and maintain reliability over 100,000+ power cycles.

Queendom Solution

Queendom supplied through-hole board-mount indicator LEDs in T-1 3/4 (5mm) and T-1 (3mm) packages for PLC status indication panels. Available in red, green, yellow, blue, and white with water-clear or diffused lenses, these LEDs provide reliable visual status indication for industrial automation PLC systems. The wide operating temperature range and high ESD resistance ensure stable performance in harsh industrial environments.

Key Advantages:

  • SMD 0805: Compact footprint for dense PCB arrays
  • Luminous intensity: 5-15 mcd at 20mA
  • Viewing angle: 120 diffused
  • Reflow: Pb-free 260C (JEDEC J-STD-020)
  • Reliability: 100,000+ power cycles, -40C to +85C
