556 Series Constant Intensity Panel Mount Indicators are designed for rugged, outdoor applications. Combining InGaN and AlInGaP technologies, the series delivers maximum light output in a highly durable package designed for 1-in. mounting holes in applications ranging from instrument panels and agricultural controls to transportation, environmental monitoring equipment, display lighting, and much more.
Providing reliable visibility, the series offers continuous indication in battery-operated equipment that will not decline as voltage depletes. Built for rugged conditions, the 556 Series is IP66, NEMA 4X rated, and RoHS compliant with 6C exemption.
The 556 Series is available in two options:
- Daylight viewable with a clear, flat UV-stabilized polycarbonate lens over a colored LED for even distribution of light and maximum visibility at any angle.
- Standard PMI, available with a flat or domed, tinted, polycarbonate lens over colored LEDs. The standard series is also IK07 certified for impact resistance.
Both are built to operate between 18 to 48V DC and at extreme operating temperatures ranging from -30° to +85°C (22° to +185°F). Each unit comes in red, green or yellow with a white or black nickel-plated brass housing and nut. Terminals are hot solder dip with 6-32 screw terminal connection.
