Precision Light Guide Solutions for Industrial Indication.
About Us
Focused on Precision Light Guide Components for Industrial Systems.
Topten Light Guide focuses on the design and manufacturing of precision light guide components used in industrial electronic systems.
Designed for Precision Industrial Indication
Our light guide solutions are developed around optical isolation, compact multi-channel layout, flexible development support, and installation-oriented structural design.
Anti-Crosstalk
Precision Optical Isolation for High-Density Industrial Indicators
High-Density Indicator Layout
Compact Multi-Channel Light Guide Solutions for Space-Constrained Designs
Modern industrial electronics increasingly require compact indicator modules capable of displaying multiple signal states within limited front-panel space.
High-density light guide structures make it possible to integrate multiple indicators into a small area while maintaining clear light separation, consistent visibility, and a clean panel layout.
Optimized optical geometry helps maintain uniform brightness and a consistent visual appearance across all indicator positions.

Tolerance-Friendly Pin Designs for Stable and Efficient Assembly
Reliable installation is a critical aspect of light guide design. During assembly, variations in PCB hole diameter, hole position, or insertion alignment can affect mounting stability and optical consistency.
Topten light guide products incorporate specialized pin geometries to accommodate different assembly conditions. Each structure is engineered for specific installation scenarios, tolerance ranges, and mechanical requirements.
Conical Pin
- •Small mounting holes
- •Limited assembly space
- •Fast insertion and alignment
- •Compatible with smaller panel or PCB holes
- •Smooth insertion reduces assembly resistance
- •Suitable for fast and high-volume assembly
Slotted Cylindrical Pin
- •Multi-position press-fit installation
- •Assemblies with multiple mounting pins
- •Modules requiring improved tolerance adaptability
- •Slot design relieves assembly stress
- •Reduced sensitivity to hole diameter and alignment tolerances
- •Helps maintain module geometry and optical alignment
- •Easier installation and removal
2nd Generation Reinforced Thread Pin
- •Industrial environments exposed to vibration or shock
- •Applications requiring stronger panel-to-PCB retention
- •Critical status indication modules that must remain secure
- •Improved thread strength and structural stability
- •More secure mounting on PCB
- •Suitable for high-vibration and long-term industrial use
Why Slot Design Improves Assembly Tolerance
TPT pin designs are engineered for industrial assembly requirements, delivering greater tolerance flexibility, easier installation, and long-term mechanical reliability through slotted and reinforced structures.
