The 1271.2004 is a 3mm 4-fold Miniature Horizontal PCB Mount Light Guide, held by means of two spigots in the circuit card. The system can be strip-mounted in grid dimensions of FEL. The light guides are used in connection with SMD LEDs. The light is led in form of a light guide by 3mm parallel to the circuit card to the front plate. It is used in electronic products that call for light to be emitted from a panel that is positioned at right angles to the circuit board. They are fitted to the circuit board by using push-fit lugs. Light guides form a key function in the human interface with a product, so their appearance and optical quality have a huge influence on aesthetics and overall perceptions. The options of horizontal light guides with square, round or rectangular displays provide design engineers with ultimate flexibility. MENTOR light guides are visibly superior, premium-quality precision optics that will enhance the appearance of any electronic device.
