The rear-mounted light guides, from MENTOR, are designed for use with front panels. The rear-mounting method enables the light guide head to be the same size as the hole within the front panel. Standard front panel light guides require a larger head than the mounting hole, which is not fully illuminated by the LED. Therefore the rear-mounted light guides often have a flush and more attractive appearance.
This range of light guides can be mechanically fixed through the radial compression of slightly oversized rings moulded within their body. Minimum recommended thickness of the front panel is 1.5 mm.
Suitable applications for the rear-mounted light guides for front panels include; medical devices, security safety, communications equipment and industrial control.

Features of the rear-mounted light guides:
Variety of head shapes
Material: clear PC UL94
Ambient temperature: -20°C to +50°C
Inject face: straight

LED Light Pipes, MENTOR - Front Panels

MENTOR light guides are designed to transmit light from a PCB-mounted LED to the desired user interface. This transfer is completed with little or no loss of luminance and no light bleed between adjacent elements.
This vast range of light guides are available in single or multiple light guide options, with a range of head shapes and sizes. These options allow them to provide a solution for all sorts of applications. They also offer simple installation and high ESD protection.
Front panel light guides are ideal for applications where the light guide is not attached to the PCB. They push-fit into a hole in the front panel with the light-inject face close to the LED. Front panel light guides therefore provide a variety of design options.
