Size: MFFF/FMMM Compact, durable multibranch cable connector designed for reliable electrical splitting and longterm outdoor use. Built for installations that require low loss, low heat, and secure sealed connections. Key benefits Reduced energy loss and heat generation: quality tinned copper conductors provide stable conductivity while resisting corrosion and oxidation, extending service life and maintaining performance. Improved reliability in harsh environments: Integrated sealing around intermediate wire connections limits dust and moisture entry, preventing signal degradation and maintaining consistent operation. Easier installation and flexible placement: Generous cable lengths for each configuration reduce the need for extensions and make routing simpler in tight or remote installations. Durable connector housing: PPO construction offers strong mechanical and thermal properties plus fireretardant behavior for safer use in demanding applications. Main features Material: Tinned copper conductors for corrosion resistance, reduced oxidation, and lower energy loss and heat. Connector housing: Made of PPO for durability and fireretardant performance. Integrated sealing: Intermediate wire connections are edged and sealed to limit dust and moisture ingress and preserve cable performance. Cable length options: 2to4 and 2to6 configurations: total lengths of 38 cm and 55 cm respectively 2to8 configuration: total lengths of 58 cm and 77 cm Size designation: MFFF and FMMM to match corresponding mating connectors and installation needs. Why you need this product Prevents performance drop caused by corroded or oxidized conductors through use of tinned copper. Minimizes heat buildup and electrical loss in multibranch connections. Protects critical intermediate joints from contaminants with an integrated sealed design. Saves time and materials by supplying appropriate cable lengths for most installation layouts. Typical applications Solar PV and renewable power systems for splitting panel outputs to string inputs or microinverter connections. Outdoor LED lighting and signage where moisture resistance and longterm reliability are required. Industrial and commercial wiring where multibranch distribution and secure sealed joints are needed. Practical notes Choose the configuration (2to4, 2to6, or 2to8) and the required total cable length variant to match your installation layout. The MFFF and FMMM size options correspond to compatible mating connectors; verify compatibility before installation. The sealed, edged intermediate connections and robust PPO housing make this connector suitable for outdoor and semiexposed indoor installations where durability matters.
