发布于: 2026-07-29 22:38

The status indicator lights of PLC and automation control cabinet are the first entry point for production line diagnosis: power supply, operation, communication, and faults are clear at a glance. Dust, oil pollution, and electromagnetic interference are severe in industrial sites, and lamp beads must have industrial grade reliability. Hongcheng Optoelectronics provides a full range of PLC indicator LEDs for automation manufacturers.

Key points for selecting PLC panel indicator lights

  • Industrial grade quality: A-class chip, gold wire packaging, HBM ≥ 2000V anti-static, suitable for industrial sites.
  • Package selection: IO status lights are arranged in high-density 0603/0805 patch, while panel lights are inserted in 5mm straight.
  • Color specifications: green=running, red=fault, yellow=warning/mandatory, dual color beads save light positions.
  • Communication indicator: The communication transmitter and receiver lights should flash quickly without any trailing shadows, and the standard model with fast response should be selected.
  • Batch matching: supports matching according to BOM whole order, and ensures consistency with BIN sorting for the entire container.
