RJE1R288335403 is a stackable modular jack featuring two 8P8C ports (2×1 configuration) with shielded design and through-hole mounting for PCB integration. The connector is constructed with phosphor bronze contacts featuring 50 µm minimum gold plating on mating areas and 50 µm minimum nickel overall, housed in high-temperature engineering thermoplastic (UL 94V-0 rated) with stainless steel shield and tin-finished ground tabs. Electrically, it is rated for 125 VAC, 1.25 A per contact, with 500 MO minimum insulation resistance and 1,500 VAC dielectric strength (contact to shield). The device operates across -40°C to +85°C and mates with modular plugs conforming to TIA 1096, making it suitable for structured cabling, network infrastructure, and industrial communication systems requiring robust shielded connectivity.
