3mm CBI, Triple-Level – Circuit Board Indicator 3mm LED
The 3mm CBI, triple-level circuit board indicator LED is a specialized indicator solution designed for compact PCBs that require multi-status signaling in a vertical stack format. As part of the CBI (Circuit Board Indicator) LED family, this triple-level configuration provides three independent LED positions in one robust housing, making it an ideal choice for applications that demand space efficiency, clear visibility, and reliable multi-color or multi-status indication.
Whether used in instrumentation, telecommunications, servers, or industrial control panels, the 3mm CBI triple-level LED indicator delivers consistent optical performance with simplified PCB integration.
Key Features
Triple-Level LED Design
This indicator incorporates three vertically aligned 3mm LEDs, allowing engineers to display three independent status conditions in a single footprint. This stacked configuration reduces board space usage and enables tidy, organized indicator layouts.
Uniform 3mm LED Illumination
Each LED in the triple-level assembly uses a high-quality 3mm round LED, available in single colors, bi-color, or tri-color options depending on system requirements. The optical output is stable, bright, and easily visible in various environments.
Precise PCB Alignment
The housing is engineered to ensure perfect alignment when mounted onto printed circuit boards. This eliminates LED angle variations and promotes professional, consistent panel appearance.
High-Contrast Indicator Windows
A molded black or dark housing enhances contrast, allowing the illuminated LEDs to stand out clearly in daylight or under strong ambient lighting.
Multiple Lens Options
Depending on application needs, devices may use:
-
Water-clear lenses for maximum brightness
-
Diffused lenses for wide-angle soft illumination
-
Tinted lenses for enhanced color distinction
Durable Housing for Industrial Use
Made from heat-resistant, UL 94V-0 rated materials, this triple-level CBI unit withstands harsh manufacturing processes such as wave soldering.
RoHS-Compliant
Fully compliant with environmental standards, ensuring safe and green electronic product design.
