Product catalog summary
Overview: The 604 Series Panel Indicator LED is designed for industrial and external applications, featuring a compact Ø5.0mm mounting size in a nickel-plated brass housing. It is sealed to IP67 standards, making it weatherproof and suitable for high vibration environments.
Features and Benefits:
  • Available in a range of LED colors and voltage options.
  • Wide viewing angle with a flat smoked lens for good on/off contrast.
  • 150mm flying leads for rapid installation.
  • Manufactured with an internal resistor for outstanding reliability and vandal resistance.
Technical Specifications:
  • Operating temperature ranges from -40°C to +85°C for most colors, with some extending to +100°C.
  • Typical forward voltage and current values vary by color and model, with luminous intensity and wavelength specified for each.
  • Cool White LED emission colors are specified by X-Y coordinates.
Design Considerations:
  • Electro-Static Discharge (ESD) precautions are essential during manufacturing and assembly.
  • Forward voltage/current values depend on ambient temperature; operation outside specified ranges is not recommended.
Materials:
  • Body and nut are made of bright nickel-plated brass.
  • Lens is polycarbonate, and encapsulation is black polyurethane.
  • Termination features 150mm color-coded flying leads, compliant with Defence Standard 61/12, Part 18.
Technical Drawing and De-rating Graphs: The document includes technical drawings and de-rating graphs for forward current against ambient temperature for different LED colors.
