Marl International has extended its industrial and defence LED panel indicator range with 677 and 697 series of panel indicators. One of the LED indicators offers NVIS (night vision) radiance, making it suitable for use by operators wearing military NVIS goggles.
Both panel indicators feature high degree of EMC protection, with an internal stainless steel mesh behind the lens to provide continuity of screening as well as a conductive panel seal. The lamps are sealed to IP67 and are available in chrome-plated aluminium housings. They are potted for vibration applications. They have a smoked lens to give a good on and off contrast ratio.
The 677 series is available in red, yellow, green, blue and cool white in 12 and 24V versions and has an internal reverse protection diode fitted as standard. The 697 series is available in green only, and is designed for military panels and it emits radiance to MIL-85762A standards.
