Brush Pass-Through Frames
Brush pass-through frames are cable entry components designed to route cables through enclosure walls, panels, or cabinets while protecting cables and limiting dust and debris ingress. These frames use integrated brush strips that surround the cables and form a flexible barrier, allowing cables to pass through while maintaining enclosure protection.
Unlike sealed cable glands, brush cable entry frames are ideal for applications where cables need to be frequently added, removed, or repositioned. The brush design accommodates cables with or without connectors and allows installation without disconnecting or modifying existing cable assemblies.
Brush pass-through frames also help reduce airflow leakage and filter dust and larger particles while allowing cable movement. This helps protect sensitive equipment and maintain controlled airflow in enclosures and cabinets.
These cable entry solutions are commonly used alongside related cable management and entry components to ensure proper cable routing, protection, and enclosure performance.
Key Features and Benefits of Brush Cable Entry Frames
Brush pass-through frames provide several advantages for industrial cable entry and cable management systems:
- Flexible brush seal allows cables with connectors to pass through easily
- Provides protection against dust, debris, and contaminants
- Reduces airflow leakage while allowing cable movement
- Protects cables from abrasion and damage at entry points
- Allows quick installation and retrofit without disconnecting cables
- Supports multiple cables through a single entry point
Brush cable entry frames are commonly made from durable materials such as polyamide, steel, or reinforced plastics designed for industrial environments.
Frequently Asked Questions
What is the difference between a brush pass-through frame and a cable gland?
Brush pass-through frames allow flexible cable entry and easy cable movement, while cable glands provide tight sealing and strain relief for individual cables.
Can brush pass-through frames be used with pre-terminated cables?
Yes. Brush cable entry frames allow cables with connectors to pass through without disconnecting or modifying the cable assembly.
Do brush pass-through frames affect airflow inside enclosures?h3>
They help reduce unwanted airflow while allowing cables to pass through, improving enclosure thermal management.
