515-1253-0590F is a variable-length, right-angle Optopipe® light pipe from Dialight's 515 Series, designed to direct and distribute light from LEDs with a 3mm diameter output and flat lens configuration. This specific model features a housing length (Dim "A") of 0.590 inches (15.00 mm), an overall length of 1.008 inches (25.60 mm), and a height from PCB to centerline lightpipe of 0.350 inches (8.89 mm), with an overall height of 0.450 inches (11.43 mm). The light pipe operates over a temperature range of -40°C to +100°C and mounts via two 0.094-inch (2.39 mm) diameter holes on a minimum PCB thickness of 0.047 inches (1.194 mm), offering no optical crosstalk, no light bleed, and high ESD protection. This design is ideal for telecom, networking, data storage, medical, test and measurement, automation controls, EV-charging, and industrial embedded solutions where reliable LED indication with simplified board redesign is required.
