LED indicators certified for railway applications

This certification is said to pave the way to bringing energy-efficient LED technology to every rail signalling application, including control units and signal box diagrams, for both new installations and retrofits.

'With LED technology being more widely adopted in signalling applications, this certification will help designers, engineers and manufacturers deliver a highly reliable, long-term solution with better energy efficiency, reduced maintenance and lower power consumption, while still providing leading optical performance,' said Adrian Rawlinson, managing director of Marl.

High visibility is an important factor in signalling applications and the newly certified 407 series addresses this with a flat diffused assembly providing excellent viewing over a wide angle, even in sunlight, according to the company.

The 407 series is available in red, yellow, green and white, with a black precision-moulded housing that enhances mechanical stability and supports the standard-intensity LED element and internal circuitry for both 12VDC and 24VDC operation.

A flush-mounted design enables quick and efficient replacement in front panels and the mandatory 907-000-00 panel socket has also been certified by Network Rail.

The typical lifetime is 90,000 hours and operating temperatures range from -40C to +80C or -40C to +85C depending on the selected part.
