The 515-1052F is a 4-element lightpipe LED indicator manufactured by Dialight, designed for snap-in mounting on 0.062" thick printed circuit boards. The device features clear, transmissive polycarbonate construction (UL 94-V0 flammability rated) with precision-engineered optical elements to direct and distribute light efficiently. Key dimensional specifications include a body length of 1.260" [32 mm], width of 0.417" [10.59 mm], and height of 0.102" [2.59 mm], with an alignment pin of 0.065" diameter. The lightpipe operates reliably across a wide temperature range from -30°C to +100°C, and is RoHS compliant as indicated by the "F" suffix designation. This component is commonly used in industrial control panels, instrumentation displays, and equipment status indication applications where reliable, space-efficient light transmission is required.
