Marl LEDs look the part for a handheld industrial instrument design

Appearance is increasingly as important in industrial instrumentation as it is in consumer electronics – especially during the critical sales phase, according to Chris Hill, Managing Director of Instrument Installations. He said, “The unit is intended to professionally demonstrate the key features of the actuators in formal client presentations in the field and at the training facility. It not only had to look great, but also has to be very easy and intuitive for the sales force to use, ensuring a really slick demonstration. Being a handheld unit, we only had limited space available. We specified the Marl 512 Series LED as it fitted the bill in terms of both size and appearance.”

He continued, “We sought LED technology as the unit is powered by the actuator – and the Marl LEDs draw a very low current from the 24V supply. The fact that the product is designed and manufactured by a quality UK company was also a substantial benefit.”

Each unit features five Marl 512 Series LEDs, in yellow, green and red. Marl 512 Series panel mount LEDs feature a robust bright nickel plated brass housing, which gave Instrument Installations the aesthetic appearance they sought and are just 27mm deep behind the panel, a sufficiently low profile for the handheld mobile actuator demonstration units. Other features of the 12.7mm diameter 512 Series LEDs include IP67 protection, resistance to vibration and a smoked lens. An internal reverse protection diode is fitted as standard. Marl also offers the LEDs in white and blue.
