RJCSE508101 is a single port surface mount jack connector with 8 positions and 8 contacts, designed for unshielded applications with integrated dual LEDs and RoHS compliance. The connector features a high-temperature thermoplastic housing (UL 94V-0 rated, black color) with phosphor bronze contacts and selective gold plating on mating surfaces, including a 50 µm minimum nickel underplate and matte-tin or gold flash on contact tails. The integrated LED indicators support multiple color configurations (single or bi-color options) with forward voltage of 2.1 V typical and luminous intensity of 0.5 mCd minimum at 2 mA. Key dimensional specifications include a panel cutout of 0.522 inches minimum width by 0.639 inches minimum height, with mounting holes of 0.128 inches diameter (±0.002 inches) and maximum coplanarity of 0.10 inches between all terminal tails. This connector is ideal for network interface applications, telecommunications equipment, and industrial control systems requiring visual status indication through integrated LED feedback.
