Marl Yellow LED Panel Mount Indicator 28V DC, 12.7 mm Mount Hole, Solder Tab, IP67, 531-521-63

The Marl 531-521-63 Yellow LED Panel Mount Indicator is designed for use in industrial, instrumentation, and control panel applications where a robust and clear visual indication is required. This panel mount LED indicator features a discrete yellow LED, providing a vivid alert in machinery, electrical enclosures, and control desks.

With a 12.7 mm mounting hole, this indicator is easy to install on standard panels. The device operates with a maximum supply voltage of 28V DC, offering flexibility for integration in different panel designs and DC control circuits. The maximum forward current is rated at 16 mA, ensuring energy-efficient operation without compromising on brightness.

The indicator is housed in bright nickel plated brass, providing excellent durability and resistance to corrosion. The device is fully internally potted, which protects internal components against shock and vibration, making it ideal for use in environments prone to movement, impact, or high levels of mechanical stress. The IP67 sealing ensures the indicator is protected against dust and immersion in water up to one meter, supporting reliable year-round performance even in harsh or outdoor industrial settings.

Electrically, the indicator uses a solder tab termination, simplifying integration and ensuring a firm connection within your control circuitry. The yellow LED achieves a luminous intensity up to 600 mcd, ensuring the indication remains visible and unmistakable in both brightly lit and dim control rooms. It is designed as a single-colour indicator, eliminating confusion and providing a dedicated signal point for system states.

Compliance with CE, UKCA, and RoHS directives ensures that the Marl 531-521-63 is suitable for use in regulated environments and meets common international standards for safety, environmental impact, and performance. The indicator's length is 37 mm, allowing for compact installation without interfering with nearby panel elements or instrumentation.

Key applications include control desks, automation panels, electrical distribution boards, industrial machinery, marine equipment, and any scenario where an easily noticeable and rugged Panel Mount LED Indicator is desired. The combination of robust construction, clear illumination, and high ingress protection makes it suitable for manufacturing, process control, HVAC, and water treatment industries.

Choose this LED indicator for scenarios where clarity, reliability, and durability are essential in panel signalling systems. Explore other high-quality Marl panel mount indicators for a range of voltage, colour, and mounting options in our Electronics Components section.
