IP66-rated Panel Mount LED Indicators from LEDtronics

LEDtronics PT503B


April 21, 2020

                LEDtronics PT503B series LED panel indicators

LEDtronics has released a series of indicator lamps geared to harsh environments where durability and accurate light reading are vital, if not life-dependent. Rated to IP66, the new PT503B series of panel mount LED indicators is fully protected against dust and solid objects, in addition to being protected against powerful water jets projected by a nozzle from any direction. Able to operate in extreme conditions, the next-generation line also opens potential new markets for LEDtronics, which is already a leader in LED panel indicators. Handheld instruments used in high-moisture environments is one example.

Offering negligible heat generation and sunlight-visible LED light colors, the PT503B series of energy-saving panel indicators is expected to have high demand by such industries as defense and aerospace, utilities, industrial automation, robotics and automotive. Applications for the new panel indicator mirror those of others in LEDtronics’ catalog, including industrial panels for powerplants and other environments, pilot lights for machines and instruments, and automotive indicators in such vehicles as tractors and trailers.

With a low power draw of only 0.1 watts, the PT503B series of direct incandescent-replacement LED panel indicators offers a 90 percent reduction in power consumption compared to incandescent counterparts.

The new panel indicators are LEDtronics’ first to feature male tab terminal connectors for easier installation. Typically, this provides sharper, faster and higher-intensity illumination and better visibility than standard lamps.

The lamps feature a flush-flat, tinted, polycarbonate plastic lens that resists impact, provides an optimal viewing angle of 60 degrees and maximizes light dispersion. They are enclosed in low-profile, threaded black PA66 nylon housing with black bezel, and fit 8mm (0.316-inch) mounting hole diameter for panels 0.5mm to 8.0mm thick.

The series is offered in a choice of voltages – 6VDC, 12VDC, 24VDC, 120VAC – and is available in 522nm Aqua Green, 464nm Super Blue, 629nm Super Red, 591nm Super Yellow and 8700K~11000K Cool White illumination colors.
