PFL2 & PFL3 Panel Mount Flat Lens Light Pipes

Introduction

VCC’s PFL2 and PFL3 series are panel-mount flat-lens light pipes designed to carry light from an internal source to a front-panel viewing point. The family is offered in 2 mm and 3 mm diameter options, combining a flush countersink mounting approach with integrated press-fit crush ribs for secure panel installation.

The series is technically notable for addressing both optical indication and mechanical retention in a compact front-panel component. Its optical-grade polycarbonate construction supports light transfer from compatible LED or traditional light sources, while the flat lens provides a clean panel-facing interface.

What it does

PFL2 and PFL3 light pipes route illumination from a compatible light source behind a panel to a visible front-panel indicator. This can simplify the placement of the light source by separating the illuminated viewing point from the source itself.

The light pipes use a flat lens and are intended for flush panel integration through a countersink mounting style. Integrated crush ribs provide a press-fit installation feature intended to hold the part securely in the panel, including in installations subject to vibration.

The family is available in multiple lengths and configurations, with 2 mm and 3 mm diameter options. Its UL 94V-0 optical-grade polycarbonate material is also specified as halogen-free.

Applications

• Front-panel status and indicator light routing
• Equipment panels requiring flush-mounted visual indicators
• LED-based indication systems where the LED is positioned behind or away from the panel surface
• Legacy or mixed-source indicator designs using compatible traditional light sources
• Panel interfaces that benefit from press-fit, crush-rib retention

Design considerations

The selected PFL2 or PFL3 version should match the required 2 mm or 3 mm diameter, as well as the needed light-pipe length and configuration. Panel design must accommodate the countersink mounting style and the press-fit crush-rib installation feature.

Because the component transfers light from a separate source, the mechanical relationship between the source, light pipe, and panel opening should be considered during integration. The specified compatibility with a wide range of LED and traditional light sources provides flexibility, but the intended source arrangement should be verified for the chosen configuration.

The flat lens and flush panel integration approach may be useful where a low-profile front-panel appearance is required. Material selection is also relevant for systems requiring UL 94V-0 optical-grade polycarbonate and halogen-free construction.
