Product Description

Marl 677-521-04 Yellow Panel Mount Indicator is a professional-grade component tailored for use in electronic assemblies, control panels, and signaling equipment requiring high-visibility and reliability. This LED indicator emits a bright yellow light and features a 20mA rated current, making it efficient for low-power, long-life applications. The solder tab termination enables quick and secure wiring, streamlining integration into existing systems.

The indicator incorporates a durable black anodized aluminum housing and a 7mm high-contrast smoked polycarbonate lens, ensuring both visual clarity and robust protection against harsh conditions. Its compact 29mm body and recessed bezel minimize protrusion, maintaining a flush panel appearance and reducing the risk of accidental impacts. The mounting hole size of 8.1mm allows for universal panel fitting in most industrial enclosures.

Yellow LED for immediate equipment or status indication. 20mA current consumption optimizes energy use. Solder tab connection simplifies assembly and maintenance. IP67 protection seals against dust entry and water immersion, suitable for outdoor or wash-down environments.

Supplied with sealing washer, fixing nut, and lock washer for secure, leak-proof installation.

This model is fully internally potted for shock and vibration resistance, making it ideal for demanding industrial, transportation, and process control applications. The D-shaped mounting prevents indicator rotation, ensuring consistent orientation and visual alignment.
