Robust and NVIS compatible LED panel indicators

Marl International has extended its industrial and defence LED panel indicator range with two robust series featuring exceptionally high EMC screening. One of the new LED indicators offers NVIS (Night VISion) radiance, making it suitable for use by operators wearing military night vision goggles.

Marl 677 and 697 panel indicators are specifically designed to address the most demanding applications. Both series benefit from an exceptionally 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. Sealed to IP67, the lamps are supplied in robust chrome plated aluminium housings and are fully potted for high vibration applications. They have a smoked lens to give a good on/off contrast ratio.

The 677 series is offered in red, yellow, green, blue and cool white in 12V and 24V versions and has an internal reverse protection diode fitted as standard. The 697 series is available in green only, and is specifically designed for military panels where operators may be wearing night vision aids. It emits radiance to Mil-85762A standards, for compatibility with NVIS panel displays used by operators wearing night vision aids.
