J599 2-fiber 2-electrical connector integrates optical and electrical functions, enabling simultaneous transmission of multiple optical and electrical signals. Constructed with stainless steel, it is suitable for long-term operation in harsh environments such as acidic/alkaline conditions, corrosive atmospheres, and marine climates. The plug and socket feature five-key alignment with blind-mate and anti-misinsertion capabilities, utilizing a three-thread quick-connect design with anti-loosening mechanisms. It supports multi-core simultaneous connection and blind insertion; It offers low connection loss and high reliability, with features including waterproofing, dustproofing, harsh environment resistance, and corrosion resistance. Currently available configurations include 2-fiber/2-electrical and 2-fiber/4-electrical. The 2-fiber/2-electrical model uses a 13-series housing, while the 2-fiber/4-electrical model uses a 15-series housing. Customization is available upon customer request.
