Bel Stewart Connector’s MRJ21 cable assembly products are designed to support increased patch panel density in
telecom and premise wiring applications. This modular cabling platform supports network applications such as Gigabit Ethernet, Voice
over Internet Protocol (VoIP), and Power over Ethernet (PoE). Cable connection options include left or right 45 degree angle, or 180
degree straight cable exit to facilitate various routing schemes to component racks. In addition, these cable assemblies allow a connection
migration path from legacy products including punch down blocks, modular plug breakouts, and standard RJ21 to MRJ21 assemblies.
Designed with a die cast backshell for shielded applications, Bel Stewart’s MRJ21 cable assemblies are durability tested to 500 cycles to
ensure unsurpassed quality and performance. Jackscrews provide a secure cable connection while the robust boardlock design allows superior
PCB strain relief. For additional product information visit our Ethernet connectivity webpage at www.belstewart.com
