MRJ21 Cable Assemblies

Bel Stewart’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 and right 45 degree exits as well as a 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 punchdown blocks, modular plug breakouts, and standard RJ21 to MRJ21 assemblies.

Designed with a die cast backshell for shielding applications, Bel Stewart’s MRJ21 cable assemblies are durability tested to 500 cycles to insure unsurpassed quality and performance. Robust jackscrews provide a secure cable connection while the sturdy boardlock design allows superior PCB strain relief.
