528 SeriesAt 13mm mounting, our 528 Series is one of our larger panel mounting LED indicators.

Featuring a high intensity LED element, the 528 Series is specifically designed for applications operating in demanding environments.

Aircraft were using older Neon indicators in their hot water dispensers; today Neon’s have been replaced with Marl’s 528 Series LED indicators giving more reliability and a modern appearance.

The dispenser manufacturer used the same input voltage (110Vac) and mounting hole. This allowed the manufacturer to upgrade the indicators with minimal change to the unit itself. 

The improved appearance and increased reliability resulted in the manufacturer’s sales increasing.

The 528 Series is ideally suited to environments where the operator requires clear, decisive and reliable equipment status indication.
