Dialight T-1 3mm Green/Red Bi-Level LED Indicator, 2 LEDs, 2mA

The Dialight 553-0212F is a compact and precise 3mm Bi-Level LED indicator, designed for clear status signalling in electronic assemblies. Featuring both green and red LEDs within a single, tinted diffused lens, this component offers a reliable visual output for various applications. Its right-angle viewing design and cathode right polarity make it ideal for installations where space is limited and correct orientation is critical.

This indicator operates at a low forward current of just 2mA for both colours, ensuring energy efficiency and compatibility with low-power circuits. The green LED emits a peak wavelength of 565nm, while the red LED emits at 635nm, providing a distinct and easily discernible colour change. The integrated lens offers a wide 60° viewing angle, ensuring the status is visible from a broad perspective.

Key Specifications & Features

• Bi-Level Display: Integrates two distinct LED colours (green and red) in one 3mm (T-1) through-hole package.
• Low Power Consumption: Efficient operation with a forward current of 2mA per colour.
• Right-Angle Design: Allows for PCB mounting where the indicator face is perpendicular to the board, saving space and enabling front-panel visibility.
• Clear Optical Performance: Luminous intensity of 1.6mcd for both colours, paired with a tinted diffused lens for even light distribution.
• Standard Centrelines: Features a 2.54mm LED centrelines for compatibility with standard PCB layouts.

Constructed for reliability and ease of integration, this through-hole mount indicator is a fundamental component for engineers and technicians requiring dependable status indication in control panels, test equipment, and consumer electronics.
