The LPA-C011301S-4 is a 3mm single-unit surface-mount technology (SMT) vertical light pipe designed to direct and amplify LED light output in compact indicator applications. The device features a clear polycarbonate (UL94V-O) light pipe lens paired with a black Noryl (UL94V-O) holder, with a 4mm length dimension as specified by the -4 suffix. It is constructed with precision-molded optical components and includes two 1.00 mm diameter mounting holes on a 3.78 mm pitch for secure PCB attachment. The light pipe operates across a wide temperature range of -60°C to +125°C and is compatible with the recommended SWL-LX0805xx series LEDs. This component is ideal for status indicators, panel displays, and other applications requiring efficient light transmission and visual feedback in space-constrained designs.
