3mm Quad-Level LED CBI – Multi-Color Circuit Board Indicator (10×4×20mm)
The 3mm Quad-Level LED CBI (Circuit Board Indicator) is engineered for applications that demand high-density visual signaling within a compact panel or PCB footprint. With a vertical quad-level configuration, this indicator features four precisely aligned LED positions, making it ideal for multi-status displays, step indicators, and stacked signal interfaces. Measuring 10×4×20mm, this module delivers efficient illumination, excellent contrast, and long-term reliability across industrial, commercial, and consumer applications.
Available in single-color, bi-color, tri-color, and four-color combinations, the quad-level CBI offers unmatched flexibility for system designers needing multiple states or status signals in one compact, unified assembly.
Key Features
✔ Quad-Level Vertical LED Arrangement
The four stacked LED positions allow designers to represent multi-step status levels, progress indicators, signal hierarchies, or operational sequences without increasing horizontal board space. This is especially beneficial for compact devices, dense PCBs, and front-panel arrangements.
✔ 3mm LED Package for Universal Compatibility
The standard 3mm round LED format ensures compatibility with existing footprints, fixtures, and light guide systems. This size provides a balance of brightness, durability, and lens options to suit a wide range of interface designs.
✔ Pre-Formed Leads for Precision Alignment
Each LED level includes pre-formed, consistent lead spacing to guarantee perfect alignment when mounted on the PCB. This eliminates manual lead bending, reduces assembly errors, and ensures highly uniform installation during mass production.
✔ High-Contrast Black Housing
The PA66 black housing reduces stray reflection and enhances LED contrast, providing superior readability across ambient lighting conditions—ideal for industrial control rooms and device dashboards.
✔ Long-Life LED Chip Technology
Built with high-efficiency LED chips, each indicator offers:
-
Stable luminous intensity
-
Uniform brightness across all four levels
-
Excellent thermal stability for long operating life
This ensures consistent system performance and reduces maintenance requirements.
✔ Industrial-Grade Materials & Compliance
-
UL 94V-0 rated PA66 housing: flame-retardant and durable
-
Halogen-free construction
-
Fully RoHS compliant
These properties support safe deployment in global commercial and industrial markets.
✔ Multi-Color Options
Available configurations include:
-
Single-color (Red, Green, Yellow, Blue, White)
-
Bi-color (e.g., Red/Green, Red/Yellow)
-
Tri-color
-
Four-color combos
These variants allow designers to create layered visual signals without requiring multiple indicator modules.
